Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

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

Types

type CloudRedisCallOptions

type CloudRedisCallOptions struct {
	ListInstances  []gax.CallOption
	GetInstance    []gax.CallOption
	CreateInstance []gax.CallOption
	UpdateInstance []gax.CallOption
	DeleteInstance []gax.CallOption
}

CloudRedisCallOptions contains the retry settings for each method of CloudRedisClient.

type CloudRedisClient

type CloudRedisClient struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient

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

func NewCloudRedisClient

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

NewCloudRedisClient creates a new cloud redis client.

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
Example
ctx := context.Background()
c, err := redis.NewCloudRedisClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c
Output:

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 the client's connection to the API service.

func (*CloudRedisClient) CreateInstance

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

By default, the instance is peered to the project's default network (at /compute/docs/networks-and-firewalls#networks).

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

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
Output:

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.

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

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

err = op.Wait(ctx)
// TODO: Handle error.
Output:

func (*CloudRedisClient) DeleteInstanceOperation

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

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

func (*CloudRedisClient) GetInstance

GetInstance gets the details of a specific Redis instance.

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

req := &redispb.GetInstanceRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.GetInstance(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp
Output:

func (*CloudRedisClient) ListInstances

ListInstances 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.

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

req := &redispb.ListInstancesRequest{
	// TODO: Fill request struct fields.
}
it := c.ListInstances(ctx, req)
for {
	resp, err := it.Next()
	if err == iterator.Done {
		break
	}
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}
Output:

func (*CloudRedisClient) UpdateInstance

UpdateInstance updates the metadata and configuration of a specific Redis instance.

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

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

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