Cloud Spanner Instance Admin API v1 - Package cloud.google.com/go/spanner/admin/instance/apiv1 (v1.61.0)

Package instance is an auto-generated package for the Cloud Spanner Instance Admin API.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

• Authentication and Authorization
• Timeouts and Cancellation
• Testing against Client Libraries
• Debugging Client Libraries
• Inspecting errors

Example usage

To get started with this package, create a client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := instance.NewInstanceAdminClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &instancepb.CreateInstanceRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/spanner/admin/instance/apiv1/instancepb#CreateInstanceRequest.
}
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

Use of Context

The ctx passed to NewInstanceAdminClient 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.

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

InstanceAdminInstanceConfigPath returns the path for the instance config resource.

Deprecated: Use

fmt.Sprintf("projects/%s/instanceConfigs/%s", project, instanceConfig)

instead.

InstanceAdminInstancePath returns the path for the instance resource.

Deprecated: Use

fmt.Sprintf("projects/%s/instances/%s", project, instance)

instead.

InstanceAdminProjectPath returns the path for the project resource.

Deprecated: Use

fmt.Sprintf("projects/%s", project)

instead.

CreateInstanceConfigOperation manages a long-running operation from CreateInstanceConfig.

Done reports whether the long-running operation has completed.

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.
