Options Hash (options):

  • :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 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 or a Systems Manager document. For more information, go to the

    Template Anatomy][1

    in the 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 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 CloudFormation to create the stack.

    • `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your Amazon Web Services account; for example, by creating new 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, 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 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

      CloudFormation.

      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 CloudFormation being notified.

      For more information, see [Using 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 Amazon Web Services resources), `Custom::*` (for all custom resources), `Custom::logical_ID ` (for a specific custom resource), `AWS::service_name::*` (for all resources of a particular Amazon Web Services service), and `AWS::service_name::resource_logical_ID ` (for a specific Amazon Web Services resource).

    If the list of resource types doesn't include a resource that you're creating, the stack creation fails. By default, CloudFormation grants permissions to all resource types. Identity and Access Management (IAM) uses this parameter for CloudFormation-specific condition keys in IAM policies. For more information, see [Controlling Access with 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 Identity and Access Management (IAM) role that CloudFormation assumes to create the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, 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, CloudFormation uses the role that was previously associated with the stack. If no role is available, 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 *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. 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 CloudFormation knows that you're not attempting to create a stack with the same name. You might retry `CreateStack` requests to ensure that 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 *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.

    ({})

Options Hash (options):

  • :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, 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 Identity and Access Management (IAM) role that CloudFormation assumes to delete the stack. CloudFormation uses the role's credentials to make calls on your behalf.

    If you don't specify a value, CloudFormation uses the role that was previously associated with the stack. If no role is available, 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 CloudFormation knows that you're not attempting to delete a stack with the same name. You might retry `DeleteStack` requests to ensure that 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`.

Options Hash (options):

  • :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 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 or a Systems Manager document. For more information, go to [Template Anatomy] in the 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 CloudFormation to update the stack.

    • `CAPABILITY_IAM` and `CAPABILITY_NAMED_IAM`

      Some stack templates might include resources that can affect permissions in your Amazon Web Services account; for example, by creating new 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, 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 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

      CloudFormation.

      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 CloudFormation being notified.

      For more information, see [Using 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, CloudFormation grants permissions to all resource types. Identity and Access Management (IAM) uses this parameter for CloudFormation-specific condition keys in IAM policies. For more information, see [Controlling Access with 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 Identity and Access Management (IAM) role that CloudFormation assumes to update the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, 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, CloudFormation uses the role that was previously associated with the stack. If no role is available, CloudFormation uses a temporary session that is generated from your user credentials.

  • :rollback_configuration (Types::RollbackConfiguration)

    The rollback triggers for 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 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. 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, CloudFormation doesn't modify the stack's tags. If you specify an empty value, CloudFormation removes all associated tags.

  • :disable_rollback (Boolean)

    Preserve the state of previously provisioned resources when an operation fails.

    Default: `False`

  • :client_request_token (String)

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

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::CloudFormation::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

## Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

## Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

## Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

## 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
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

## Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

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

attempts attempt in seconds invoked before each attempt invoked before each wait
