Overview

Configures and manages Cloud Memorystore for Redis instances

Google Cloud Memorystore for Redis v1beta1

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 refering to a GCP +region+; for example:

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

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, lib_name: nil, lib_version: "") ⇒ CloudRedisClient

Returns a new instance of CloudRedisClient

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) —

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

Instance Method Details

#create_instance(parent, instance_id, instance, options: nil) ⇒ Google::Gax::Operation

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

By default, the instance is peered to 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:

require "google/cloud/redis/v1beta1"

cloud_redis_client = Google::Cloud::Redis::V1beta1.new
formatted_parent = Google::Cloud::Redis::V1beta1::CloudRedisClient.location_path("[PROJECT]", "[LOCATION]")
instance_id = "test_instance"
tier = :BASIC
memory_size_gb = 1
instance = { tier: tier, memory_size_gb: memory_size_gb }

# Register a callback during the method call.
operation = cloud_redis_client.create_instance(formatted_parent, instance_id, instance) do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Or use the return value to register a callback.
operation.on_done do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Manually reload the operation.
operation.reload!

# Or block until the operation completes, triggering callbacks on
# completion.
operation.wait_until_done!

Parameters:

  • parent (String) —

    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) —

    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.

  • instance (Google::Cloud::Redis::V1beta1::Instance | Hash) —

    Required. A Redis [Instance] resource A hash of the same form as Google::Cloud::Redis::V1beta1::Instance can also be provided.

  • options (Google::Gax::CallOptions) —

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

#list_instances(parent, page_size: nil, options: nil) ⇒ Google::Gax::PagedEnumerable<Google::Cloud::Redis::V1beta1::Instance>

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:

require "google/cloud/redis/v1beta1"

cloud_redis_client = Google::Cloud::Redis::V1beta1.new
formatted_parent = Google::Cloud::Redis::V1beta1::CloudRedisClient.location_path("[PROJECT]", "[LOCATION]")

# Iterate over all results.
cloud_redis_client.list_instances(formatted_parent).each do |element|
  # Process element.
end

# Or iterate over results one page at a time.
cloud_redis_client.list_instances(formatted_parent).each_page do |page|
  # Process each page at a time.
  page.each do |element|
    # Process element.
  end
end

Parameters:

  • parent (String) —

    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) —

    The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

  • options (Google::Gax::CallOptions) —

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

Returns:

  • (Google::Gax::PagedEnumerable<Google::Cloud::Redis::V1beta1::Instance>) —

    An enumerable of Google::Cloud::Redis::V1beta1::Instance instances. See Google::Gax::PagedEnumerable documentation for other operations such as per-page iteration or access to the response object.

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.

Parameters:

  • update_mask (Google::Protobuf::FieldMask | Hash) —

    Required. Mask of fields to update. At least one path must be supplied in this field. The elements of the repeated paths field may only include these fields from Instance:

    • +display_name+
    • +labels+
    • +memory_size_gb+
    • +redis_config+ A hash of the same form as Google::Protobuf::FieldMask can also be provided.
  • instance (Google::Cloud::Redis::V1beta1::Instance | Hash) —

    Required. Update description. Only fields specified in update_mask are updated. A hash of the same form as Google::Cloud::Redis::V1beta1::Instance can also be provided.

  • options (Google::Gax::CallOptions) —

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

Returns:

  • (Google::Gax::Operation)

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
