Package cloud.google.com/go/redis/apiv1

Package redis is an auto-generated package for the Google Cloud Memorystore for Redis API.

Creates and manages Redis instances on the Google Cloud Platform.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

CloudRedisCallOptions

type CloudRedisCallOptions struct {
	ListInstances    []gax.CallOption
	GetInstance      []gax.CallOption
	CreateInstance   []gax.CallOption
	UpdateInstance   []gax.CallOption
	UpgradeInstance  []gax.CallOption
	ImportInstance   []gax.CallOption
	ExportInstance   []gax.CallOption
	FailoverInstance []gax.CallOption
	DeleteInstance   []gax.CallOption
}

CloudRedisCallOptions contains the retry settings for each method of CloudRedisClient.

CloudRedisClient

type CloudRedisClient struct {

	// The call options for this service.
	CallOptions *CloudRedisCallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

CloudRedisClient is a client for interacting with Google Cloud Memorystore for Redis API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

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

func NewCloudRedisClient

func NewCloudRedisClient(ctx context.Context, opts ...option.ClientOption) (*CloudRedisClient, error)

NewCloudRedisClient creates a new cloud redis client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

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:

Example

package main

import (
	redis "cloud.google.com/go/redis/apiv1"
	"context"
)

func main() {
	ctx := context.Background()
	c, err := redis.NewCloudRedisClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (*CloudRedisClient) Close

func (c *CloudRedisClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*CloudRedisClient) Connection

func (c *CloudRedisClient) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated.

func (*CloudRedisClient) CreateInstance

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

By default, the instance is accessible from the project’s default network (at https://cloud.google.com/vpc/docs/vpc).

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.

Example

package main

import (
	redis "cloud.google.com/go/redis/apiv1"
	"context"
	redispb "google.golang.org/genproto/googleapis/cloud/redis/v1"
)

func main() {
	ctx := context.Background()
	c, err := redis.NewCloudRedisClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &redispb.CreateInstanceRequest{
		// TODO: Fill request struct fields.
	}
	op, err := c.CreateInstance(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	resp, err := op.Wait(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

func (*CloudRedisClient) CreateInstanceOperation

func (c *CloudRedisClient) CreateInstanceOperation(name string) *CreateInstanceOperation

CreateInstanceOperation returns a new CreateInstanceOperation from a given name. The name must be that of a previously created CreateInstanceOperation, possibly from a different process.

func (*CloudRedisClient) DeleteInstance

DeleteInstance deletes a specific Redis instance. Instance stops serving and data is deleted.
