### Method Details

`cancel(name, body=None, x__xgafv=None)`

    Cancel a Job.

    Args:
      name: string, Required. Job name. (required)
      body: object, The request body.
        The object takes the form of:

    { # CancelJob Request.
      "requestId": "A String", # Optional. An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. The server will guarantee that for at least 60 minutes after the first request. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).
    }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # This resource represents a long-running operation that is the result of a network API call.
      "done": True or False, # If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
      "error": { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors). # The error result of the operation in case of failure or cancellation.
        "code": 42, # The status code, which should be an enum value of google.rpc.Code.

            "a_key": "", # Properties of the object. Contains field @type with type URL.
          },
        ],
        "message": "A String", # A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
      },
      "metadata": { # Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.
        "a_key": "", # Properties of the object. Contains field @type with type URL.
      },
      "name": "A String", # The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`.
      "response": { # The normal, successful response of the operation. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
        "a_key": "", # Properties of the object. Contains field @type with type URL.
      },
    }

If the `type` specifies a local SSD, this field should be a multiple of 375 GB, otherwise, the final size will be the next greater multiple of 375 GB. **Boot Disk**: Batch will calculate the boot disk size based on source image and task requirements if you do not speicify the size. If both this field and the `boot_disk_mib` field in task spec's `compute_resource` are defined, Batch will only honor this field. Also, this field should be no smaller than the source disk's size when the `data_source` is set as `snapshot` or `image`. For example, if you set an image as the `data_source` field and the image's default disk size 30 GB, you can only use this field to make the disk larger or equal to 30 GB.

If undefined, the default value is `2000`. If you also define the VM's machine type using the `machineType` in [InstancePolicy](https://cloud.google.com/batch/docs/reference/rest/v1/projects.locations.jobs#instancepolicy) field or inside the `instanceTemplate` in the [InstancePolicyOrTemplate](https://cloud.google.com/batch/docs/reference/rest/v1/projects.locations.jobs#instancepolicyortemplate) field, make sure the CPU resources for both fields are compatible with each other and with how many tasks you want to allow to run on the same VM at the same time. For example, if you specify the `n2-standard-2` machine type, which has 2 vCPUs each, you are recommended to set `cpuMilli` no more than `2000`, or you are recommended to run two tasks on the same VM if you set `cpuMilli` to `1000` or less.

Format the value of this field as a time limit in seconds followed by `s`—for example, `3600s` for 1 hour. The field accepts any value between 0 and the maximum listed for the `Duration` field type at https://protobuf.dev/reference/protobuf/google.protobuf/#duration; however, the actual maximum run time for a job will be limited to the maximum run time for a job listed at https://cloud.google.com/batch/quotas#max-job-duration.

Background runnables are allowed continue running in the background while the task executes subsequent runnables. For example, background runnables are useful for providing services to other runnables or providing debugging-support tools like SSH servers. Specifically, background runnables are killed automatically (if they have not already exited) a short time after all foreground runnables have completed.

When `enableImageStreaming` is set to true, the container runtime is [containerd](https://containerd.io/) instead of Docker. Additionally, this container runnable only supports the following `container` subfields: `imageUri`, `commands[]`, `entrypoint`, and `volumes[]`; any other `container` subfields are ignored.

Use Image streaming to allow the runnable to initialize without waiting for the entire container image to download, which can significantly reduce startup time for large container images. When `enableImageStreaming` is set to true, the container runtime is [containerd](https://containerd.io/) instead of Docker. Additionally, this container runnable only supports the following `container` subfields: `imageUri`, `commands[]`, `entrypoint`, and `volumes[]`; any other `container` subfields are ignored. For more information about the requirements and limitations for using Image streaming with Batch, see the [`image-streaming` sample on GitHub](https://github.com/GoogleCloudPlatform/batch-samples/tree/main/api-samples/image-streaming).

For security, it is strongly recommended to specify an encrypted password by using a Secret Manager secret: `projects/*/secrets/*/versions/*`. Warning: If you specify the password using plain text, you risk the password being exposed to any users who can view the job or its logs. To avoid this risk, specify a secret that contains the password instead.

You can either specify the username directly by using plain text or specify an encrypted username by using a Secret Manager secret: `projects/*/secrets/*/versions/*`. However, using a secret is recommended for enhanced security. Caution: If you specify the username using plain text, you risk the username being exposed to any users who can view the job or its logs. To avoid this risk, specify a secret that contains the username instead.

If the `TaskSpec.Volumes` field is specified but this field is not, Batch will mount each volume from the host machine to the container with the same mount path by default. In this case, the default mount option for containers will be read-only (`ro`) for existing persistent disks and read-write (`rw`) for other volume types, regardless of the original mount options specified in `TaskSpec.Volumes`. If you need different mount settings, you can explicitly configure them in this field.
