Package batch is an auto-generated package for the Batch API.

An API to manage the running of Batch resources on Google Cloud Platform.

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

To get started with this package, create a client.

// go get cloud.google.com/go/batch/apiv1@latest
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 := batch.NewClient(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.

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

req := &batchpb.CancelJobRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/batch/apiv1/batchpb#CancelJobRequest.
}
op, err := c.CancelJob(ctx, req)
if err != nil {
    // TODO: Handle error.
}

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

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.

func DefaultAuthScopes() []string

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

CallOptions contains the retry settings for each method of Client.

type CancelJobOperation struct {
	// contains filtered or unexported fields
}

CancelJobOperation manages a long-running operation from CancelJob.

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.

type Client struct {

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

	// 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
}

Client is a client for interacting with Batch API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Google Batch Service. The service manages user submitted batch jobs and allocates Google Compute Engine VM instances to run the jobs.

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

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

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

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

type DeleteJobOperation struct {
	// contains filtered or unexported fields
}

DeleteJobOperation manages a long-running operation from DeleteJob.

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.

IamPolicyCallOptions contains the retry settings for each method of IamPolicyClient.

type IamPolicyClient struct {

	// The call options for this service.
	CallOptions *IamPolicyCallOptions
	// contains filtered or unexported fields
}

IamPolicyClient is a client for interacting with Batch API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Manages Identity and Access Management (IAM) policies.

Any implementation of an API that offers access control features implements the google.iam.v1.IAMPolicy interface.

Data modelAccess control is applied when a principal (user or service account), takes some action on a resource exposed by a service. Resources, identified by URI-like names, are the unit of access control specification. Service implementations can choose the granularity of access control and the supported permissions for their resources. For example one database service may allow access control to be specified only at the Table level, whereas another might allow access control to also be specified at the Column level.

This is intentionally not a CRUD style API because access control policies are created and deleted implicitly with the resources to which they are attached.

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

CancelOperation is a utility method from google.longrunning.Operations.

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

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

DeleteOperation is a utility method from google.longrunning.Operations.

GetIamPolicy gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

GetLocation gets information about a location.

GetOperation is a utility method from google.longrunning.Operations.

ListLocations lists information about the supported locations for this service.

ListOperations is a utility method from google.longrunning.Operations.

SetIamPolicy sets the access control policy on the specified resource. Replaces any existing policy.

Can return NOT_FOUND, INVALID_ARGUMENT, and PERMISSION_DENIED errors.

TestIamPermissions returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may “fail open” without warning.

type JobIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.

	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.

JobIterator manages a stream of *batchpb.Job.

func (it *JobIterator) All() iter.Seq2[*batchpb.Job, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

PageInfo supports pagination. See the [google.golang.org/api/iterator] package for details.
