#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials. This can be an instance of any one of the following classes:

    • ‘Aws::Credentials` - Used for configuring static, non-refreshing credentials.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::SharedCredentials` - Used for loading credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    When ‘true`, an attempt is made to coerce request parameters into the required types.

  • :disable_host_prefix_injection (Boolean) — default: false —

    Set to true to disable SDK automatically adding host prefix to default service endpoint when available.

  • :endpoint (String) —

    The client endpoint is normally constructed from the ‘:region` option. You should only configure an `:endpoint` when connecting to test endpoints. This should be avalid HTTP(S) URI.

  • :endpoint_cache_max_entries (Integer) — default: 1000 —

    Used for the maximum size limit of the LRU cache storing endpoints data for endpoint discovery enabled operations. Defaults to 1000.

#cancel_update_stack(params = {}) ⇒ Struct

Cancels an update on the specified stack. If the call completes successfully, the stack rolls back the update and reverts to the previous stack configuration.

<note markdown=“1”> You can cancel only stacks that are in the UPDATE_IN_PROGRESS state.

</note>

Examples:

Request syntax with placeholder values


resp = client.cancel_update_stack({
  stack_name: "StackName", # required
  client_request_token: "ClientRequestToken",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name or the unique stack ID that is associated with the stack.

  • :client_request_token (String) —

    A unique identifier for this ‘CancelUpdateStack` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to cancel an update on a stack with the same name. You might retry ‘CancelUpdateStack` requests to ensure that AWS CloudFormation successfully received them.

Returns:

  • (Struct) —

    Returns an empty response.

end

#continue_update_rollback(params = {}) ⇒ Struct

For a specified stack that is in the ‘UPDATE_ROLLBACK_FAILED` state, continues rolling it back to the `UPDATE_ROLLBACK_COMPLETE` state. Depending on the cause of the failure, you can manually [ fix the error] and continue the rollback. By continuing the rollback, you can return your stack to a working state (the `UPDATE_ROLLBACK_COMPLETE` state), and then try to update the stack again.

A stack goes into the ‘UPDATE_ROLLBACK_FAILED` state when AWS CloudFormation cannot roll back all changes after a failed stack update. For example, you might have a stack that is rolling back to an old database instance that was deleted outside of AWS CloudFormation. Because AWS CloudFormation doesn’t know the database was deleted, it assumes that the database instance still exists and attempts to roll back to it, causing the update rollback to fail.

[1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html#troubleshooting-errors-update-rollback-failed

Examples:

Request syntax with placeholder values


resp = client.continue_update_rollback({
  stack_name: "StackNameOrId", # required
  role_arn: "RoleARN",
  resources_to_skip: ["ResourceToSkip"],
  client_request_token: "ClientRequestToken",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name or the unique ID of the stack that you want to continue rolling back.

    <note markdown=“1”> Don’t specify the name of a nested stack (a stack that was created by using the ‘AWS::CloudFormation::Stack` resource). Instead, use this operation on the parent stack (the stack that contains the `AWS::CloudFormation::Stack` resource).

    </note>
  • :role_arn (String) —

    The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to roll back the stack. AWS CloudFormation uses the role’s credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don’t have permission to pass it. Ensure that the role grants least privilege.

    If you don’t specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

  • :resources_to_skip (Array<String>) —

    A list of the logical IDs of the resources that AWS CloudFormation skips during the continue update rollback operation. You can specify only resources that are in the ‘UPDATE_FAILED` state because a rollback failed. You can’t specify resources that are in the ‘UPDATE_FAILED` state for other reasons, for example, because an update was cancelled. To check why a resource update failed, use the DescribeStackResources action, and view the resource status reason.

    Specify this property to skip rolling back resources that AWS CloudFormation can’t successfully roll back. We recommend that you [ troubleshoot] resources before skipping them. AWS CloudFormation sets the status of the specified resources to ‘UPDATE_COMPLETE` and continues to roll back the stack. After the rollback is complete, the state of the skipped resources will be inconsistent with the state of the resources in the stack template. Before performing another stack update, you must update the stack or resources to be consistent with each other. If you don’t, subsequent stack updates might fail, and the stack will become unrecoverable.

    Specify the minimum number of resources required to successfully roll back your stack. For example, a failed resource update might cause dependent resources to fail. In this case, it might not be necessary to skip the dependent resources.

    To skip resources that are part of nested stacks, use the following format: ‘NestedStackName.ResourceLogicalID`. If you want to specify the logical ID of a stack resource (`Type: AWS::CloudFormation::Stack`) in the `ResourcesToSkip` list, then its corresponding embedded stack must be in one of the following states: `DELETE_IN_PROGRESS`, `DELETE_COMPLETE`, or `DELETE_FAILED`.

    <note markdown=“1”> Don’t confuse a child stack’s name with its corresponding logical ID defined in the parent stack. For an example of a continue update rollback operation with nested stacks, see [Using ResourcesToSkip to recover a nested stacks hierarchy].

  • :client_request_token (String) —

    A unique identifier for this ‘ContinueUpdateRollback` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to continue the rollback to a stack with the same name. You might retry ‘ContinueUpdateRollback` requests to ensure that AWS CloudFormation successfully received them.

Returns:

  • (Struct) —

    Returns an empty response.

#create_change_set(params = {}) ⇒ Types::CreateChangeSetOutput

Creates a list of changes that will be applied to a stack so that you can review the changes before executing them. You can create a change set for a stack that doesn’t exist or an existing stack. If you create a change set for a stack that doesn’t exist, the change set shows all of the resources that AWS CloudFormation will create. If you create a change set for an existing stack, AWS CloudFormation compares the stack’s information with the information that you submit in the change set and lists the differences. Use change sets to understand which resources AWS CloudFormation will create or change, and how it will change resources in an existing stack, before you create or update a stack.

To create a change set for a stack that doesn’t exist, for the ‘ChangeSetType` parameter, specify `CREATE`. To create a change set for an existing stack, specify `UPDATE` for the `ChangeSetType` parameter. To create a change set for an import operation, specify `IMPORT` for the `ChangeSetType` parameter. After the `CreateChangeSet` call successfully completes, AWS CloudFormation starts creating the change set. To check the status of the change set or to review it, use the DescribeChangeSet action.

When you are satisfied with the changes the change set will make, execute the change set by using the ExecuteChangeSet action. AWS CloudFormation doesn’t make changes until you execute the change set.

Examples:

Response structure


resp.id #=> String
resp.stack_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name or the unique ID of the stack for which you are creating a change set. AWS CloudFormation generates the change set by comparing this stack’s information with the information that you submit, such as a modified template or different parameter input values.

  • :template_body (String) —

    A structure that contains the body of the revised template, with a minimum length of 1 byte and a maximum length of 51,200 bytes. AWS CloudFormation generates the change set by comparing this template with the template of the stack that you specified.

    Conditional: You must specify only ‘TemplateBody` or `TemplateURL`.

  • :template_url (String) —

    The location of the file that contains the revised template. The URL must point to a template (max size: 460,800 bytes) that is located in an S3 bucket. AWS CloudFormation generates the change set by comparing this template with the stack that you specified.

    Conditional: You must specify only ‘TemplateBody` or `TemplateURL`.

  • :use_previous_template (Boolean) —

    Whether to reuse the template that is associated with the stack to create the change set.

  • :parameters (Array<Types::Parameter>) —

    A list of ‘Parameter` structures that specify input parameters for the change set. For more information, see the Parameter data type.

  • :capabilities (Array<String>) —

    In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to create the stack.

    • ‘CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your AWS account; for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge this by specifying one of these capabilities.

      The following IAM resources require you to specify either the ‘CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.

      • If you have IAM resources, you can specify either capability.

      • If you have IAM resources with custom names, you must specify ‘CAPABILITY_NAMED_IAM`.

      • If you don’t specify either of these capabilities, AWS CloudFormation returns an ‘InsufficientCapabilities` error.

      If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.

      • AWS::IAM::AccessKey][1
      • AWS::IAM::Group][2
      • AWS::IAM::InstanceProfile][3
      • AWS::IAM::Policy][4
      • AWS::IAM::Role][5
      • AWS::IAM::User][6
      • AWS::IAM::UserToGroupAddition][7

      For more information, see [Acknowledging IAM Resources in AWS CloudFormation Templates].

    • ‘CAPABILITY_AUTO_EXPAND`

      Some template contain macros. Macros perform custom processing on templates; this can include simple actions like find-and-replace operations, all the way to extensive transformations of entire templates. Because of this, users typically create a change set from the processed template, so that they can review the changes resulting from the macros before actually creating the stack. If your stack template contains one or more macros, and you choose to create a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. This includes the [AWS::Include] and

      AWS::Serverless][10

      transforms, which are macros hosted by AWS

      CloudFormation.

      <note markdown=“1”> This capacity does not apply to creating change sets, and specifying it when creating change sets has no effect.

      Also, change sets do not currently support nested stacks. If you

      want to create a stack from a stack template that contains macros and nested stacks, you must create or update the stack directly from the template using the CreateStack or UpdateStack action, and specifying this capability.

      </note>

      For more information on macros, see [Using AWS CloudFormation Macros to Perform Custom Processing on Templates].

  • :resource_types (Array<String>) —

    The template resource types that you have permissions to work with if you execute this change set, such as ‘AWS::EC2::Instance`, `AWS::EC2::*`, or `Custom::MyCustomInstance`.

    If the list of resource types doesn’t include a resource type that you’re updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for condition keys in IAM policies for AWS CloudFormation. For more information, see

    Controlling Access with AWS Identity and Access Management][1

    in the

    AWS CloudFormation User Guide.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html

  • :role_arn (String) —

    The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes when executing the change set. AWS CloudFormation uses the role’s credentials to make calls on your behalf. AWS CloudFormation uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don’t have permission to pass it. Ensure that the role grants least privilege.

    If you don’t specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

  • :rollback_configuration (Types::RollbackConfiguration) —

    The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.

  • :notification_arns (Array<String>) —

    The Amazon Resource Names (ARNs) of Amazon Simple Notification Service (Amazon SNS) topics that AWS CloudFormation associates with the stack. To remove all associated notification topics, specify an empty list.

  • :tags (Array<Types::Tag>) —

    Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to resources in the stack. You can specify a maximum of 50 tags.

  • :change_set_name (required, String) —

    The name of the change set. The name must be unique among all change sets that are associated with the specified stack.

    A change set name can contain only alphanumeric, case sensitive characters and hyphens. It must start with an alphabetic character and cannot exceed 128 characters.

  • :client_token (String) —

    A unique identifier for this ‘CreateChangeSet` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to create another change set with the same name. You might retry ‘CreateChangeSet` requests to ensure that AWS CloudFormation successfully received them.

  • :description (String) —

    A description to help you identify this change set.

  • :change_set_type (String) —

    The type of change set operation. To create a change set for a new stack, specify ‘CREATE`. To create a change set for an existing stack, specify `UPDATE`. To create a change set for an import operation, specify `IMPORT`.

    If you create a change set for a new stack, AWS Cloudformation creates a stack with a unique stack ID, but no template or resources. The stack will be in the [ ‘REVIEW_IN_PROGRESS` ][1] state until you execute the change set.

    By default, AWS CloudFormation specifies ‘UPDATE`. You can’t use the ‘UPDATE` type to create a change set for a new stack or the `CREATE` type to create a change set for an existing stack.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-describing-stacks.html#d0e11995

  • :resources_to_import (Array<Types::ResourceToImport>) —

    The resources to import into your stack.

Response structure


resp.stack_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name that is associated with the stack. The name must be unique in the region in which you are creating the stack.

    <note markdown=“1”> A stack name can contain only alphanumeric characters (case sensitive) and hyphens. It must start with an alphabetic character and cannot be longer than 128 characters.

    </note>
  • :template_body (String) —

    Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information, go to

    Template Anatomy][1

    in the AWS CloudFormation User Guide.

    Conditional: You must specify either the ‘TemplateBody` or the `TemplateURL` parameter, but not both.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html

  • :template_url (String) —

    Location of file containing the template body. The URL must point to a template (max size: 460,800 bytes) that is located in an Amazon S3 bucket. For more information, go to the [Template Anatomy] in the AWS CloudFormation User Guide.

    Conditional: You must specify either the ‘TemplateBody` or the `TemplateURL` parameter, but not both.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html

  • :parameters (Array<Types::Parameter>) —

    A list of ‘Parameter` structures that specify input parameters for the stack. For more information, see the [Parameter] data type.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_Parameter.html

  • :disable_rollback (Boolean) —

    Set to ‘true` to disable rollback of the stack if stack creation failed. You can specify either `DisableRollback` or `OnFailure`, but not both.

    Default: ‘false`

  • :rollback_configuration (Types::RollbackConfiguration) —

    The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.

  • :timeout_in_minutes (Integer) —

    The amount of time that can pass before the stack status becomes CREATE_FAILED; if ‘DisableRollback` is not set or is set to `false`, the stack will be rolled back.

  • :notification_arns (Array<String>) —

    The Simple Notification Service (SNS) topic ARNs to publish stack related events. You can find your SNS topic ARNs using the SNS console or your Command Line Interface (CLI).

  • :capabilities (Array<String>) —

    In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to create the stack.

    • ‘CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your AWS account; for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge this by specifying one of these capabilities.

      The following IAM resources require you to specify either the ‘CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.

      • If you have IAM resources, you can specify either capability.

      • If you have IAM resources with custom names, you must specify ‘CAPABILITY_NAMED_IAM`.

      • If you don’t specify either of these capabilities, AWS CloudFormation returns an ‘InsufficientCapabilities` error.

      If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.

      • AWS::IAM::AccessKey][1
      • AWS::IAM::Group][2
      • AWS::IAM::InstanceProfile][3
      • AWS::IAM::Policy][4
      • AWS::IAM::Role][5
      • AWS::IAM::User][6
      • AWS::IAM::UserToGroupAddition][7

      For more information, see [Acknowledging IAM Resources in AWS CloudFormation Templates].

    • ‘CAPABILITY_AUTO_EXPAND`

      Some template contain macros. Macros perform custom processing on templates; this can include simple actions like find-and-replace operations, all the way to extensive transformations of entire templates. Because of this, users typically create a change set from the processed template, so that they can review the changes resulting from the macros before actually creating the stack. If your stack template contains one or more macros, and you choose to create a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. This includes the [AWS::Include] and

      AWS::Serverless][10

      transforms, which are macros hosted by AWS

      CloudFormation.

      Change sets do not currently support nested stacks. If you want to create a stack from a stack template that contains macros and nested stacks, you must create the stack directly from the template using this capability.

      You should only create stacks directly from a stack template that contains macros if you know what processing the macro performs.

      Each macro relies on an underlying Lambda service function for

      processing stack templates. Be aware that the Lambda function owner can update the function operation without AWS CloudFormation being notified.

      For more information, see [Using AWS CloudFormation Macros to Perform Custom Processing on Templates].

  • :resource_types (Array<String>) —

    The template resource types that you have permissions to work with for this create stack action, such as ‘AWS::EC2::Instance`, `AWS::EC2::*`, or `Custom::MyCustomInstance`. Use the following syntax to describe template resource types: `AWS::*` (for all AWS resource), `Custom::*` (for all custom resources), `Custom::logical_ID ` (for a specific custom resource), `AWS::service_name::*` (for all resources of a particular AWS service), and `AWS::service_name::resource_logical_ID ` (for a specific AWS resource).

    If the list of resource types doesn’t include a resource that you’re creating, the stack creation fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see [Controlling Access with AWS Identity and Access Management].

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html

  • :role_arn (String) —

    The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to create the stack. AWS CloudFormation uses the role’s credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don’t have permission to pass it. Ensure that the role grants least privilege.

    If you don’t specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

  • :on_failure (String) —

    Determines what action will be taken if stack creation fails. This must be one of: DO_NOTHING, ROLLBACK, or DELETE. You can specify either ‘OnFailure` or `DisableRollback`, but not both.

    Default: ‘ROLLBACK`

  • :stack_policy_body (String) —

    Structure containing the stack policy body. For more information, go to [ Prevent Updates to Stack Resources] in the *AWS CloudFormation User Guide*. You can specify either the ‘StackPolicyBody` or the `StackPolicyURL` parameter, but not both.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/protect-stack-resources.html

  • :stack_policy_url (String) —

    Location of a file containing the stack policy. The URL must point to a policy (maximum size: 16 KB) located in an S3 bucket in the same region as the stack. You can specify either the ‘StackPolicyBody` or the `StackPolicyURL` parameter, but not both.

  • :tags (Array<Types::Tag>) —

    Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to the resources created in the stack. A maximum number of 50 tags can be specified.

  • :client_request_token (String) —

    A unique identifier for this ‘CreateStack` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to create a stack with the same name. You might retry ‘CreateStack` requests to ensure that AWS CloudFormation successfully received them.

    All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a ‘CreateStack` operation with the token `token1`, then all the `StackEvents` generated by that operation will have `ClientRequestToken` set as `token1`.

    In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: ‘Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.

  • :enable_termination_protection (Boolean) —

    Whether to enable termination protection on the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see [Protecting a Stack From Being Deleted] in the *AWS CloudFormation User Guide*. Termination protection is disabled on stacks by default.

    For [nested stacks], termination protection is set on the root stack and cannot be changed directly on the nested stack.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-protect-stacks.html [2]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-nested-stacks.html

})

Response structure


resp.operation_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_set_name (required, String) —

    The name or unique ID of the stack set that you want to create stack instances from.

  • :accounts (required, Array<String>) —

    The names of one or more AWS accounts that you want to create stack instances in the specified region(s) for.

  • :regions (required, Array<String>) —

    The names of one or more regions where you want to create stack instances using the specified AWS account(s).

  • :parameter_overrides (Array<Types::Parameter>) —

    A list of stack set parameters whose values you want to override in the selected stack instances.

    Any overridden parameter values will be applied to all stack instances in the specified accounts and regions. When specifying parameters and their values, be aware of how AWS CloudFormation sets parameter values during stack instance operations:

    • To override the current value for a parameter, include the parameter and specify its value.

    • To leave a parameter set to its present value, you can do one of the following:

      • Do not include the parameter in the list.

      • Include the parameter and specify ‘UsePreviousValue` as `true`. (You cannot specify both a value and set `UsePreviousValue` to `true`.)

    • To set all overridden parameter back to the values specified in the stack set, specify a parameter list but do not include any parameters.

    • To leave all parameters set to their present values, do not specify this property at all.

    During stack set updates, any parameter values overridden for a stack instance are not updated, but retain their overridden value.

    You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use

    UpdateStackSet][1

    to update the stack set template.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html

  • :operation_preferences (Types::StackSetOperationPreferences) —

    Preferences for how AWS CloudFormation performs this stack set operation.

  • :operation_id (String) —

    The unique identifier for this stack set operation.

    The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.

    If you don’t specify an operation ID, the SDK generates one automatically.

    Repeating this stack set operation with a new operation ID retries all stack instances whose status is ‘OUTDATED`.

    **A suitable default value is auto-generated.** You should normally not need to pass this option.**

#delete_stack(params = {}) ⇒ Struct

Deletes a specified stack. Once the call completes successfully, stack deletion starts. Deleted stacks do not show up in the DescribeStacks API if the deletion has been completed successfully.

Examples:

Request syntax with placeholder values


resp = client.delete_stack({
  stack_name: "StackName", # required
  retain_resources: ["LogicalResourceId"],
  role_arn: "RoleARN",
  client_request_token: "ClientRequestToken",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name or the unique stack ID that is associated with the stack.

  • :retain_resources (Array<String>) —

    For stacks in the ‘DELETE_FAILED` state, a list of resource logical IDs that are associated with the resources you want to retain. During deletion, AWS CloudFormation deletes the stack but does not delete the retained resources.

    Retaining resources is useful when you cannot delete a resource, such as a non-empty S3 bucket, but you want to delete the stack.

  • :role_arn (String) —

    The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to delete the stack. AWS CloudFormation uses the role’s credentials to make calls on your behalf.

    If you don’t specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

  • :client_request_token (String) —

    A unique identifier for this ‘DeleteStack` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to delete a stack with the same name. You might retry ‘DeleteStack` requests to ensure that AWS CloudFormation successfully received them.

    All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a ‘CreateStack` operation with the token `token1`, then all the `StackEvents` generated by that operation will have `ClientRequestToken` set as `token1`.

resp = client.delete_stack_set({
  stack_set_name: "StackSetName", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

end

#deregister_type(params = {}) ⇒ Struct

Removes a type or type version from active use in the CloudFormation registry. If a type or type version is deregistered, it cannot be used in CloudFormation operations.

To deregister a type, you must individually deregister all registered versions of that type. If a type has only a single registered version, deregistering that version results in the type itself being deregistered.

You cannot deregister the default version of a type, unless it is the only registered version of that type, in which case the type itself is deregistered as well.

Examples:

Request syntax with placeholder values


resp = client.deregister_type({
  arn: "PrivateTypeArn",
  type: "RESOURCE", # accepts RESOURCE
  type_name: "TypeName",
  version_id: "TypeVersionId",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :arn (String) —

    The Amazon Resource Name (ARN) of the type.

    Conditional: You must specify ‘TypeName` or `Arn`.

  • :type (String) —

    The kind of type.

    Currently the only valid value is ‘RESOURCE`.

  • :type_name (String) —

    The name of the type.

    Conditional: You must specify ‘TypeName` or `Arn`.

  • :version_id (String) —

    The ID of a specific version of the type. The version ID is the value at the end of the Amazon Resource Name (ARN) assigned to the type version when it is registered.

Returns:

  • (Struct) —

    Returns an empty response.

#describe_stack_drift_detection_status(params = {}) ⇒ Types::DescribeStackDriftDetectionStatusOutput

Returns information about a stack drift detection operation. A stack drift detection operation detects whether a stack’s actual configuration differs, or has drifted, from it’s expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted. For more information on stack and resource drift, see [Detecting Unregulated Configuration Changes to Stacks and Resources].

Use DetectStackDrift to initiate a stack drift detection operation. ‘DetectStackDrift` returns a `StackDriftDetectionId` you can use to monitor the progress of the operation using `DescribeStackDriftDetectionStatus`. Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources.

#describe_stack_resource_drifts(params = {}) ⇒ Types::DescribeStackResourceDriftsOutput

Returns drift information for the resources that have been checked for drift in the specified stack. This includes actual and expected configuration values for resources where AWS CloudFormation detects configuration drift.

For a given stack, there will be one ‘StackResourceDrift` for each stack resource that has been checked for drift. Resources that have not yet been checked for drift are not included. Resources that do not currently support drift detection are not checked, and so not included. For a list of resources that support drift detection, see [Resources that Support Drift Detection].

Use DetectStackResourceDrift to detect drift on individual resources, or DetectStackDrift to detect drift on all supported resources for a given stack.

#describe_stack_resources(params = {}) ⇒ Types::DescribeStackResourcesOutput

Returns AWS resource descriptions for running and deleted stacks. If ‘StackName` is specified, all the associated resources that are part of the stack are returned. If `PhysicalResourceId` is specified, the associated resources of the stack that the resource belongs to are returned.

<note markdown=“1”> Only the first 100 resources will be returned. If your stack has more resources than this, you should use ‘ListStackResources` instead.

</note>

For deleted stacks, ‘DescribeStackResources` returns resource information for up to 90 days after the stack has been deleted.

You must specify either ‘StackName` or `PhysicalResourceId`, but not both. In addition, you can specify `LogicalResourceId` to filter the returned result. For more information about resources, the `LogicalResourceId` and `PhysicalResourceId`, go to the [AWS CloudFormation User Guide].

<note markdown=“1”> A ‘ValidationError` is returned if you specify both `StackName` and `PhysicalResourceId` in the same request.

  • :logical_resource_id (String) —

    The logical name of the resource as specified in the template.

    Default: There is no default value.

  • :physical_resource_id (String) —

    The name or unique identifier that corresponds to a physical instance ID of a resource supported by AWS CloudFormation.

    For example, for an Amazon Elastic Compute Cloud (EC2) instance, ‘PhysicalResourceId` corresponds to the `InstanceId`. You can pass the EC2 `InstanceId` to `DescribeStackResources` to find which stack the instance belongs to and what other resources are part of the stack.

    Required: Conditional. If you do not specify ‘PhysicalResourceId`, you must specify `StackName`.

    Default: There is no default value.

#detect_stack_drift(params = {}) ⇒ Types::DetectStackDriftOutput

Detects whether a stack’s actual configuration differs, or has drifted, from it’s expected configuration, as defined in the stack template and any values specified as template parameters. For each resource in the stack that supports drift detection, AWS CloudFormation compares the actual configuration of the resource with its expected template configuration. Only resource properties explicitly defined in the stack template are checked for drift. A stack is considered to have drifted if one or more of its resources differ from their expected template configurations. For more information, see [Detecting Unregulated Configuration Changes to Stacks and Resources].

Use ‘DetectStackDrift` to detect drift on all supported resources for a given stack, or DetectStackResourceDrift to detect drift on individual resources.

For a list of stack resources that currently support drift detection, see [Resources that Support Drift Detection].

‘DetectStackDrift` can take up to several minutes, depending on the number of resources contained within the stack. Use DescribeStackDriftDetectionStatus to monitor the progress of a detect stack drift operation. Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources.

When detecting drift on a stack, AWS CloudFormation does not detect drift on any nested stacks belonging to that stack. Perform ‘DetectStackDrift` directly on the nested stack itself.

[1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html [2]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift-resource-list.html

Examples:

Request syntax with placeholder values


resp = client.detect_stack_drift({
  stack_name: "StackNameOrId", # required
  logical_resource_ids: ["LogicalResourceId"],
})

Response structure


resp.stack_drift_detection_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name of the stack for which you want to detect drift.

  • :logical_resource_ids (Array<String>) —

    The logical names of any resources you want to use as filters.

#detect_stack_resource_drift(params = {}) ⇒ Types::DetectStackResourceDriftOutput

Returns information about whether a resource’s actual configuration differs, or has drifted, from it’s expected configuration, as defined in the stack template and any values specified as template parameters. This information includes actual and expected property values for resources in which AWS CloudFormation detects drift. Only resource properties explicitly defined in the stack template are checked for drift. For more information about stack and resource drift, see [Detecting Unregulated Configuration Changes to Stacks and Resources].

Use ‘DetectStackResourceDrift` to detect drift on individual resources, or DetectStackDrift to detect drift on all resources in a given stack that support drift detection.

Resources that do not currently support drift detection cannot be checked. For a list of resources that support drift detection, see [Resources that Support Drift Detection].

#detect_stack_set_drift(params = {}) ⇒ Types::DetectStackSetDriftOutput

Detect drift on a stack set. When CloudFormation performs drift detection on a stack set, it performs drift detection on the stack associated with each stack instance in the stack set. For more information, see [How CloudFormation Performs Drift Detection on a Stack Set].

‘DetectStackSetDrift` returns the `OperationId` of the stack set drift detection operation. Use this operation id with ` DescribeStackSetOperation ` to monitor the progress of the drift detection operation. The drift detection operation may take some time, depending on the number of stack instances included in the stack set, as well as the number of resources included in each stack.

Once the operation has completed, use the following actions to return drift information:

  • Use ‘ DescribeStackSet ` to return detailed informaiton about the stack set, including detailed information about the last completed drift operation performed on the stack set. (Information about drift operations that are in progress is not included.)

  • Use ‘ ListStackInstances ` to return a list of stack instances belonging to the stack set, including the drift status and last drift time checked of each instance.

  • Use ‘ DescribeStackInstance ` to return detailed information about a specific stack instance, including its drift status and last drift time checked.

For more information on performing a drift detection operation on a stack set, see [Detecting Unmanaged Changes in Stack Sets].

You can only run a single drift detection operation on a given stack set at one time.

To stop a drift detection stack set operation, use ‘ StopStackSetOperation `.

#execute_change_set(params = {}) ⇒ Struct

Updates a stack using the input information that was provided when the specified change set was created. After the call successfully completes, AWS CloudFormation starts updating the stack. Use the DescribeStacks action to view the status of the update.

When you execute a change set, AWS CloudFormation deletes all other change sets associated with the stack because they aren’t valid for the updated stack.

If a stack policy is associated with the stack, AWS CloudFormation enforces the policy during the update. You can’t specify a temporary stack policy that overrides the current policy.

Examples:

Request syntax with placeholder values


resp = client.execute_change_set({
  change_set_name: "ChangeSetNameOrId", # required
  stack_name: "StackNameOrId",
  client_request_token: "ClientRequestToken",
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :change_set_name (required, String) —

    The name or ARN of the change set that you want use to update the specified stack.

  • :stack_name (String) —

    If you specified the name of a change set, specify the stack name or ID (ARN) that is associated with the change set you want to execute.

  • :client_request_token (String) —

    A unique identifier for this ‘ExecuteChangeSet` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to execute a change set to update a stack with the same name. You might retry ‘ExecuteChangeSet` requests to ensure that AWS CloudFormation successfully received them.

Returns:

  • (Struct) —

    Returns an empty response.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :visibility (String) —

    The scope at which the type is visible and usable in CloudFormation operations.

    Valid values include:

    • ‘PRIVATE`: The type is only visible and usable within the account in which it is registered. Currently, AWS CloudFormation marks any types you create as `PRIVATE`.

    • ‘PUBLIC`: The type is publically visible and usable within any Amazon account.

  • :provisioning_type (String) —

    The provisioning behavior of the type. AWS CloudFormation determines the provisioning type during registration, based on the types of handlers in the schema handler package submitted.

    Valid values include:

    • ‘FULLY_MUTABLE`: The type includes an update handler to process updates to the type during stack update operations.

    • ‘IMMUTABLE`: The type does not include an update handler, so the type cannot be updated and must instead be replaced during stack update operations.

    • ‘NON_PROVISIONABLE`: The type does not include create, read, and delete handlers, and therefore cannot actually be provisioned.

  • :deprecated_status (String) —

    The deprecation status of the types that you want to get summary information about.

    Valid values include:

    • ‘LIVE`: The type is registered for use in CloudFormation operations.

    • ‘DEPRECATED`: The type has been deregistered and can no longer be used in CloudFormation operations.

  • :max_results (Integer) —

    The maximum number of results to be returned with a single call. If the number of available results exceeds this maximum, the response includes a ‘NextToken` value that you can assign to the `NextToken` request parameter to get the next set of results.

  • :next_token (String) —

    If the previous paginated request didn’t return all of the remaining results, the response object’s ‘NextToken` parameter value is set to a token. To retrieve the next set of results, call this action again and assign that token to the request object’s ‘NextToken` parameter.

#register_type(params = {}) ⇒ Types::RegisterTypeOutput

Registers a type with the CloudFormation service. Registering a type makes it available for use in CloudFormation templates in your AWS account, and includes:

  • Validating the resource schema

  • Determining which handlers have been specified for the resource

  • Making the resource type available for use in your account

For more information on how to develop types and ready them for registeration, see [Creating Resource Providers](cloudformation-cli/latest/userguide/resource-types.html) in the *CloudFormation CLI User Guide*.

Once you have initiated a registration request using ‘ RegisterType `, you can use ` DescribeTypeRegistration ` to monitor the progress of the registration request.

Examples:

Request syntax with placeholder values


resp = client.register_type({
  type: "RESOURCE", # accepts RESOURCE
  type_name: "TypeName", # required
  schema_handler_package: "S3Url", # required

    Currently, the only valid value is ‘RESOURCE`.

  • :type_name (required, String) —

    The name of the type being registered.

    We recommend that type names adhere to the following pattern: company_or_organization::service::type.

    <note markdown=“1”> The following organization namespaces are reserved and cannot be used in your resource type names:

    * `Alexa`

    • ‘AMZN`

    • ‘Amazon`

    • ‘AWS`

    • ‘Custom`

    • ‘Dev`

    </note>
  • :schema_handler_package (required, String) —

    A url to the S3 bucket containing the schema handler package that contains the schema, event handlers, and associated files for the type you want to register.

    For information on generating a schema handler package for the type you want to register, see [submit] in the *CloudFormation CLI User Guide*.

    [1]: docs.aws.amazon.com/cloudformation-cli/latest/userguide/resource-type-cli-submit.html

  • :logging_config (Types::LoggingConfig) —

    Specifies logging configuration information for a type.

  • :execution_role_arn (String) —

    The Amazon Resource Name (ARN) of the IAM execution role to use to register the type. If your resource type calls AWS APIs in any of its handlers, you must create an <a href=“https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html”>IAM execution role</a> that includes the necessary permissions to call those AWS APIs, and provision that execution role in your account. CloudFormation then assumes that execution role to provide your resource type with the appropriate credentials.

  • :client_request_token (String) —

    A unique identifier that acts as an idempotency key for this registration request. Specifying a client request token prevents CloudFormation from generating more than one version of a type from the same registeration request, even if the request is submitted multiple times.

Returns:

end

#signal_resource(params = {}) ⇒ Struct

Sends a signal to the specified resource with a success or failure status. You can use the SignalResource API in conjunction with a creation policy or update policy. AWS CloudFormation doesn’t proceed with a stack creation or update until resources receive the required number of signals or the timeout period is exceeded. The SignalResource API is useful in cases where you want to send signals from anywhere other than an Amazon EC2 instance.

Examples:

Request syntax with placeholder values


resp = client.signal_resource({
  stack_name: "StackNameOrId", # required
  logical_resource_id: "LogicalResourceId", # required
  unique_id: "ResourceSignalUniqueId", # required
  status: "SUCCESS", # required, accepts SUCCESS, FAILURE
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The stack name or unique stack ID that includes the resource that you want to signal.

  • :logical_resource_id (required, String) —

    The logical ID of the resource that you want to signal. The logical ID is the name of the resource that given in the template.

  • :unique_id (required, String) —

    A unique ID of the signal. When you signal Amazon EC2 instances or Auto Scaling groups, specify the instance ID that you are signaling as the unique ID. If you send multiple signals to a single resource (such as signaling a wait condition), each signal requires a different unique ID.

  • :status (required, String) —

    The status of the signal, which is either success or failure. A failure signal causes AWS CloudFormation to immediately fail the stack creation or update.

Returns:

  • (Struct) —

    Returns an empty response.

  stack_set_name: "StackSetName", # required
  operation_id: "ClientRequestToken", # required
})

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_set_name (required, String) —

    The name or unique ID of the stack set that you want to stop the operation for.

  • :operation_id (required, String) —

    The ID of the stack operation.

#update_stack(params = {}) ⇒ Types::UpdateStackOutput

Updates a stack as specified in the template. After the call completes successfully, the stack update starts. You can check the status of the stack via the DescribeStacks action.

To get a copy of the template for an existing stack, you can use the GetTemplate action.

Response structure


resp.stack_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stack_name (required, String) —

    The name or unique stack ID of the stack to update.

  • :template_body (String) —

    Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. (For more information, go to

    Template Anatomy][1

    in the AWS CloudFormation User Guide.)

    Conditional: You must specify only one of the following parameters: ‘TemplateBody`, `TemplateURL`, or set the `UsePreviousTemplate` to `true`.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html

  • :template_url (String) —

    Location of file containing the template body. The URL must point to a template that is located in an Amazon S3 bucket. For more information, go to [Template Anatomy] in the AWS CloudFormation User Guide.

    Conditional: You must specify only one of the following parameters: ‘TemplateBody`, `TemplateURL`, or set the `UsePreviousTemplate` to `true`.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html

  • :use_previous_template (Boolean) —

    Reuse the existing template that is associated with the stack that you are updating.

    Conditional: You must specify only one of the following parameters: ‘TemplateBody`, `TemplateURL`, or set the `UsePreviousTemplate` to `true`.

  • :stack_policy_during_update_body (String) —

    Structure containing the temporary overriding stack policy body. You can specify either the ‘StackPolicyDuringUpdateBody` or the `StackPolicyDuringUpdateURL` parameter, but not both.

    If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.

  • :stack_policy_during_update_url (String) —

    Location of a file containing the temporary overriding stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the ‘StackPolicyDuringUpdateBody` or the `StackPolicyDuringUpdateURL` parameter, but not both.

    If you want to update protected resources, specify a temporary overriding stack policy during this update. If you do not specify a stack policy, the current policy that is associated with the stack will be used.

  • :parameters (Array<Types::Parameter>) —

    A list of ‘Parameter` structures that specify input parameters for the stack. For more information, see the [Parameter] data type.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_Parameter.html

  • :capabilities (Array<String>) —

    In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to update the stack.

    • ‘CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your AWS account; for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks, you must explicitly acknowledge this by specifying one of these capabilities.

      The following IAM resources require you to specify either the ‘CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.

      • If you have IAM resources, you can specify either capability.

      • If you have IAM resources with custom names, you must specify ‘CAPABILITY_NAMED_IAM`.

      • If you don’t specify either of these capabilities, AWS CloudFormation returns an ‘InsufficientCapabilities` error.

      If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.

      • AWS::IAM::AccessKey][1
      • AWS::IAM::Group][2
      • AWS::IAM::InstanceProfile][3
      • AWS::IAM::Policy][4
      • AWS::IAM::Role][5
      • AWS::IAM::User][6
      • AWS::IAM::UserToGroupAddition][7

      For more information, see [Acknowledging IAM Resources in AWS CloudFormation Templates].

    • ‘CAPABILITY_AUTO_EXPAND`

      Some template contain macros. Macros perform custom processing on templates; this can include simple actions like find-and-replace operations, all the way to extensive transformations of entire templates. Because of this, users typically create a change set from the processed template, so that they can review the changes resulting from the macros before actually updating the stack. If your stack template contains one or more macros, and you choose to update a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. This includes the [AWS::Include] and

      AWS::Serverless][10

      transforms, which are macros hosted by AWS

      CloudFormation.

      Change sets do not currently support nested stacks. If you want to update a stack from a stack template that contains macros and nested stacks, you must update the stack directly from the template using this capability.

      You should only update stacks directly from a stack template that contains macros if you know what processing the macro performs.

      Each macro relies on an underlying Lambda service function for

      processing stack templates. Be aware that the Lambda function owner can update the function operation without AWS CloudFormation being notified.

      For more information, see [Using AWS CloudFormation Macros to Perform Custom Processing on Templates].

  • :resource_types (Array<String>) —

    The template resource types that you have permissions to work with for this update stack action, such as ‘AWS::EC2::Instance`, `AWS::EC2::*`, or `Custom::MyCustomInstance`.

    If the list of resource types doesn’t include a resource that you’re updating, the stack update fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see [Controlling Access with AWS Identity and Access Management].

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html

  • :role_arn (String) —

    The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to update the stack. AWS CloudFormation uses the role’s credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS CloudFormation uses this role even if the users don’t have permission to pass it. Ensure that the role grants least privilege.

    If you don’t specify a value, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

  • :rollback_configuration (Types::RollbackConfiguration) —

    The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.

  • :stack_policy_body (String) —

    Structure containing a new stack policy body. You can specify either the ‘StackPolicyBody` or the `StackPolicyURL` parameter, but not both.

    You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.

  • :stack_policy_url (String) —

    Location of a file containing the updated stack policy. The URL must point to a policy (max size: 16KB) located in an S3 bucket in the same region as the stack. You can specify either the ‘StackPolicyBody` or the `StackPolicyURL` parameter, but not both.

    You might update the stack policy, for example, in order to protect a new resource that you created during a stack update. If you do not specify a stack policy, the current policy that is associated with the stack is unchanged.

  • :notification_arns (Array<String>) —

    Amazon Simple Notification Service topic Amazon Resource Names (ARNs) that AWS CloudFormation associates with the stack. Specify an empty list to remove all notification topics.

  • :tags (Array<Types::Tag>) —

    Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to supported resources in the stack. You can specify a maximum number of 50 tags.

    If you don’t specify this parameter, AWS CloudFormation doesn’t modify the stack’s tags. If you specify an empty value, AWS CloudFormation removes all associated tags.

  • :client_request_token (String) —

    A unique identifier for this ‘UpdateStack` request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you’re not attempting to update a stack with the same name. You might retry ‘UpdateStack` requests to ensure that AWS CloudFormation successfully received them.

    All events triggered by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a ‘CreateStack` operation with the token `token1`, then all the `StackEvents` generated by that operation will have `ClientRequestToken` set as `token1`.

    In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format: ‘Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002`.

#update_stack_instances(params = {}) ⇒ Types::UpdateStackInstancesOutput

Updates the parameter values for stack instances for the specified accounts, within the specified regions. A stack instance refers to a stack in a specific account and region.

You can only update stack instances in regions and accounts where they already exist; to create additional stack instances, use [CreateStackInstances].

During stack set updates, any parameters overridden for a stack instance are not updated, but retain their overridden value.

You can only update the parameter values that are specified in the stack set; to add or delete a parameter itself, use

UpdateStackSet][2

to update the stack set template. If you add a

parameter to a template, before you can override the parameter value specified in the stack set you must first use [UpdateStackSet] to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using ‘UpdateStackInstances`.

Options Hash (params):

  • :stack_set_name (required, String) —

    The name or unique ID of the stack set associated with the stack instances.

  • :accounts (required, Array<String>) —

    The names of one or more AWS accounts for which you want to update parameter values for stack instances. The overridden parameter values will be applied to all stack instances in the specified accounts and regions.

  • :regions (required, Array<String>) —

    The names of one or more regions in which you want to update parameter values for stack instances. The overridden parameter values will be applied to all stack instances in the specified accounts and regions.

  • :parameter_overrides (Array<Types::Parameter>) —

    A list of input parameters whose values you want to update for the specified stack instances.

    Any overridden parameter values will be applied to all stack instances in the specified accounts and regions. When specifying parameters and their values, be aware of how AWS CloudFormation sets parameter values during stack instance update operations:

    • To override the current value for a parameter, include the parameter and specify its value.

    • To leave a parameter set to its present value, you can do one of the following:

      • Do not include the parameter in the list.

      • Include the parameter and specify ‘UsePreviousValue` as `true`. (You cannot specify both a value and set `UsePreviousValue` to `true`.)

    • To set all overridden parameter back to the values specified in the stack set, specify a parameter list but do not include any parameters.

    • To leave all parameters set to their present values, do not specify this property at all.

    During stack set updates, any parameter values overridden for a stack instance are not updated, but retain their overridden value.

    You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use ‘UpdateStackSet` to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use [UpdateStackSet] to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using `UpdateStackInstances`.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/APIReference/API_UpdateStackSet.html

  • :operation_preferences (Types::StackSetOperationPreferences) —

    Preferences for how AWS CloudFormation performs this stack set operation.

  • :operation_id (String) —

    The unique identifier for this stack set operation.

    The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.

    If you don’t specify an operation ID, the SDK generates one automatically.

    **A suitable default value is auto-generated.** You should normally not need to pass this option.**

    Conditional: You must specify only one of the following parameters: ‘TemplateBody` or `TemplateURL`—or set `UsePreviousTemplate` to true.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/template-anatomy.html

  • :use_previous_template (Boolean) —

    Use the existing template that’s associated with the stack set that you’re updating.

    Conditional: You must specify only one of the following parameters: ‘TemplateBody` or `TemplateURL`—or set `UsePreviousTemplate` to true.

  • :parameters (Array<Types::Parameter>) —

    A list of input parameters for the stack set template.

  • :capabilities (Array<String>) —

    In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to update the stack set and its associated stack instances.

    • ‘CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your AWS account; for example, by creating new AWS Identity and Access Management (IAM) users. For those stacks sets, you must explicitly acknowledge this by specifying one of these capabilities.

      The following IAM resources require you to specify either the ‘CAPABILITY_IAM` or `CAPABILITY_NAMED_IAM` capability.

      • If you have IAM resources, you can specify either capability.

      • If you have IAM resources with custom names, you must specify ‘CAPABILITY_NAMED_IAM`.

      • If you don’t specify either of these capabilities, AWS CloudFormation returns an ‘InsufficientCapabilities` error.

      If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.

      • AWS::IAM::AccessKey][1
      • AWS::IAM::Group][2
      • AWS::IAM::InstanceProfile][3
      • AWS::IAM::Policy][4
      • AWS::IAM::Role][5
      • AWS::IAM::User][6
      • AWS::IAM::UserToGroupAddition][7

      For more information, see [Acknowledging IAM Resources in AWS CloudFormation Templates].

    • ‘CAPABILITY_AUTO_EXPAND`

      Some templates contain macros. If your stack template contains one or more macros, and you choose to update a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. For more information, see [Using AWS CloudFormation Macros to Perform Custom Processing on Templates].

      Stack sets do not currently support macros in stack templates. (This includes the [AWS::Include] and [AWS::Serverless] transforms, which are macros hosted by AWS CloudFormation.) Even if you specify this capability, if you include a macro in your template the stack set operation will fail.

  • :tags (Array<Types::Tag>) —

    The key-value pairs to associate with this stack set and the stacks created from it. AWS CloudFormation also propagates these tags to supported resources that are created in the stacks. You can specify a maximum number of 50 tags.

    If you specify tags for this parameter, those tags replace any list of tags that are currently associated with this stack set. This means:

    • If you don’t specify this parameter, AWS CloudFormation doesn’t modify the stack’s tags.

    • If you specify any tags using this parameter, you must specify all the tags that you want associated with this stack set, even tags you’ve specifed before (for example, when creating the stack set or during a previous update of the stack set.). Any tags that you don’t include in the updated list of tags are removed from the stack set, and therefore from the stacks and resources as well.

    • If you specify an empty value, AWS CloudFormation removes all currently associated tags.

    If you specify new tags as part of an ‘UpdateStackSet` action, AWS CloudFormation checks to see if you have the required IAM permission to tag resources. If you omit tags that are currently associated with the stack set from the list of tags you specify, AWS CloudFormation assumes that you want to remove those tags from the stack set, and checks to see if you have permission to untag resources. If you don’t have the necessary permission(s), the entire ‘UpdateStackSet` action fails with an `access denied` error, and the stack set is not updated.

  • :operation_preferences (Types::StackSetOperationPreferences) —

    Preferences for how AWS CloudFormation performs this stack set operation.

  • :administration_role_arn (String) —

    The Amazon Resource Number (ARN) of the IAM role to use to update this stack set.

    Specify an IAM role only if you are using customized administrator roles to control which users or groups can manage specific stack sets within the same administrator account. For more information, see

    Granting Permissions for Stack Set Operations][1

    in the *AWS

    CloudFormation User Guide*.

    If you specified a customized administrator role when you created the stack set, you must specify a customized administrator role, even if it is the same customized administrator role used with this stack set previously.

    [1]: docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-prereqs.html

  • :execution_role_name (String) —

    The name of the IAM execution role to use to update the stack set. If you do not specify an execution role, AWS CloudFormation uses the ‘AWSCloudFormationStackSetExecutionRole` role for the stack set operation.

    Specify an IAM role only if you are using customized execution roles to control which stack resources users and groups can include in their stack sets.

    If you specify a customized execution role, AWS CloudFormation uses that role to update the stack. If you do not specify a customized execution role, AWS CloudFormation performs the update using the role previously associated with the stack set, so long as you have permissions to perform operations on the stack set.

  • :operation_id (String) —

    The unique ID for this stack set operation.

    The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You might retry stack set operation requests to ensure that AWS CloudFormation successfully received them.

    If you don’t specify an operation ID, AWS CloudFormation generates one automatically.

    Repeating this stack set operation with a new operation ID retries all stack instances whose status is ‘OUTDATED`.

    **A suitable default value is auto-generated.** You should normally not need to pass this option.**

  • :accounts (Array<String>) —

    The accounts in which to update associated stack instances. If you specify accounts, you must also specify the regions in which to update stack set instances.

    To update all the stack instances associated with this stack set, do not specify the ‘Accounts` or `Regions` properties.

    If the stack set update includes changes to the template (that is, if the ‘TemplateBody` or `TemplateURL` properties are specified), or the `Parameters` property, AWS CloudFormation marks all stack instances with a status of `OUTDATED` prior to updating the stack instances in the specified accounts and regions. If the stack set update does not include changes to the template or parameters, AWS CloudFormation updates the stack instances in the specified accounts and regions, while leaving all other stack instances with their existing stack instance status.

  • :regions (Array<String>) —

    The regions in which to update associated stack instances. If you specify regions, you must also specify accounts in which to update stack set instances.

    To update all the stack instances associated with this stack set, do not specify the ‘Accounts` or `Regions` properties.

    If the stack set update includes changes to the template (that is, if the ‘TemplateBody` or `TemplateURL` properties are specified), or the `Parameters` property, AWS CloudFormation marks all stack instances with a status of `OUTDATED` prior to updating the stack instances in the specified accounts and regions. If the stack set update does not include changes to the template or parameters, AWS CloudFormation updates the stack instances in the specified accounts and regions, while leaving all other stack instances with their existing stack instance status.

#update_termination_protection(params = {}) ⇒ Types::UpdateTerminationProtectionOutput

Updates termination protection for the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see [Protecting a Stack From Being Deleted] in the *AWS CloudFormation User Guide*.

For [nested stacks], termination protection is set on the root stack and cannot be changed directly on the nested stack.

#validate_template(params = {}) ⇒ Types::ValidateTemplateOutput

Validates a specified template. AWS CloudFormation first checks if the template is valid JSON. If it isn’t, AWS CloudFormation checks if the template is valid YAML. If both these checks fail, AWS CloudFormation returns a template validation error.

Examples:

Request syntax with placeholder values

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

## Basic Usage

A waiter will call an API operation until:

  • It is successful

  • It enters a terminal state

  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

## Callbacks

You can be notified before each polling attempt and before each delay. If you throw ‘:success` or `:failure` from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

## Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

## Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default ‘:delay` and `:max_attempts` values.

| waiter_name | params | :delay | :max_attempts | | ————————– | —————————– | ——– | ————- | | change_set_create_complete | #describe_change_set | 30 | 120 | | stack_create_complete | #describe_stacks | 30 | 120 | | stack_delete_complete | #describe_stacks | 30 | 120 | | stack_exists | #describe_stacks | 5 | 20 | | stack_import_complete | #describe_stacks | 30 | 120 | | stack_update_complete | #describe_stacks | 30 | 120 | | type_registration_complete | #describe_type_registration | 30 | 120 |

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {}) —

    ({})

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean) —

    Returns ‘true` if the waiter was successful.

Raises:

  • (Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError) —

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError) —

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError) —

    Raised when you request to wait for an unknown state.
