Overview

Client for the CloudRedis service.

Configures and manages Cloud Memorystore for Redis instances

Google Cloud Memorystore for Redis v1

The redis.googleapis.com service implements the Google Cloud Memorystore for Redis API and defines the following resource model for managing Redis instances:

  • The service works with a collection of cloud projects, named: /projects/*
  • Each project has a collection of available locations, named: /locations/*
  • Each location has a collection of Redis instances, named: /instances/*
  • As such, Redis instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be referring to a GCP region; for example:

  • projects/redpepper-1290/locations/us-central1/instances/my-redis

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the CloudRedis Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

#create_instance(request, options = nil) ⇒ ::Gapic::Operation #create_instance(parent: nil, instance_id: nil, instance: nil) ⇒ ::Gapic::Operation

Creates a Redis instance based on the specified tier and memory size.

By default, the instance is accessible from the project's default network.

The creation is executed asynchronously and callers may check the returned operation to track its progress. Once the operation is completed the Redis instance will be fully functional. Completed longrunning.Operation will contain the new instance object in the response field.

The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

Examples:

Basic example

require "google/cloud/redis/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Redis::V1::CloudRedis::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Redis::V1::CreateInstanceRequest.new

# Call the create_instance method.
result = client.create_instance request

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "Error!"
end

Overloads:

  • #create_instance(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to create_instance via a request object, either of type Google::Cloud::Redis::V1::CreateInstanceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Redis::V1::CreateInstanceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #create_instance(parent: nil, instance_id: nil, instance: nil) ⇒ ::Gapic::Operation

    Pass arguments to create_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The resource name of the instance location using the form: projects/{project_id}/locations/{location_id} where location_id refers to a GCP region.

    • instance_id (::String) (defaults to: nil) —

      Required. The logical name of the Redis instance in the customer project with the following restrictions:

      • Must contain only lowercase letters, numbers, and hyphens.
      • Must start with a letter.
      • Must be between 1-40 characters.
      • Must end with a number or a letter.
      • Must be unique within the customer project / location
    • instance (::Google::Cloud::Redis::V1::Instance, ::Hash) (defaults to: nil) —

      Required. A Redis [Instance] resource

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

# Call the export_instance method.
result = client.export_instance request

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60

#import_instance(request, options = nil) ⇒ ::Gapic::Operation #import_instance(name: nil, input_config: nil) ⇒ ::Gapic::Operation

Import a Redis RDB snapshot file from Cloud Storage into a Redis instance.

Redis may stop serving during this operation. Instance state will be IMPORTING for entire operation. When complete, the instance will contain only data from the imported file.

The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

Examples:

Basic example

require "google/cloud/redis/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Redis::V1::CloudRedis::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Redis::V1::ImportInstanceRequest.new

# Call the import_instance method.
result = client.import_instance request

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "Error!"
end

Overloads:

  • #import_instance(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to import_instance via a request object, either of type ImportInstanceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Redis::V1::ImportInstanceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #import_instance(name: nil, input_config: nil) ⇒ ::Gapic::Operation

    Pass arguments to import_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Required. Redis instance resource name using the form: projects/{project_id}/locations/{location_id}/instances/{instance_id} where location_id refers to a GCP region.

    • input_config (::Google::Cloud::Redis::V1::InputConfig, ::Hash) (defaults to: nil) —

      Required. Specify data to be imported.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)

Lists all Redis instances owned by a project in either the specified location (region) or all locations.

The location should have the following format:

  • projects/{project_id}/locations/{location_id}

If location_id is specified as - (wildcard), then all regions available to the project are queried, and the results are aggregated.

Examples:

Basic example

require "google/cloud/redis/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Redis::V1::CloudRedis::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Redis::V1::ListInstancesRequest.new

# Call the list_instances method.
result = client.list_instances request

# The returned object is of type Gapic::PagedEnumerable. You can
# iterate over all elements by calling #each, and the enumerable
# will lazily make API calls to fetch subsequent pages. Other
# methods are also available for managing paging directly.
result.each do |response|
  # Each element is of type ::Google::Cloud::Redis::V1::Instance.
  p response
end

Overloads:

  • #list_instances(request, options = nil) ⇒ ::Gapic::PagedEnumerable<::Google::Cloud::Redis::V1::Instance>

    Pass arguments to list_instances via a request object, either of type ListInstancesRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Redis::V1::ListInstancesRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #list_instances(parent: nil, page_size: nil, page_token: nil) ⇒ ::Gapic::PagedEnumerable<::Google::Cloud::Redis::V1::Instance>

    Pass arguments to list_instances via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • parent (::String) (defaults to: nil) —

      Required. The resource name of the instance location using the form: projects/{project_id}/locations/{location_id} where location_id refers to a GCP region.

    • page_size (::Integer) (defaults to: nil) —

      The maximum number of items to return.

      If not specified, a default value of 1000 will be used by the service. Regardless of the page_size value, the response may include a partial list and a caller should only rely on response's next_page_token to determine if there are more instances left to be queried.

    • page_token (::String) (defaults to: nil) —

      The next_page_token value returned from a previous ListInstances request, if any.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "Error!"
end

Overloads:

  • #upgrade_instance(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to upgrade_instance via a request object, either of type UpgradeInstanceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Redis::V1::UpgradeInstanceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #upgrade_instance(name: nil, redis_version: nil) ⇒ ::Gapic::Operation

    Pass arguments to upgrade_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Required. Redis instance resource name using the form: projects/{project_id}/locations/{location_id}/instances/{instance_id} where location_id refers to a GCP region.

    • redis_version (::String) (defaults to: nil) —

      Required. Specifies the target version of Redis software to upgrade to.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
