Class TaskGroup (0.17.3)

TaskGroup(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A TaskGroup defines one or more Tasks that all share the same TaskSpec.


name str
Output only. TaskGroup name. The system generates this field based on parent Job name. For example: "projects/123456/locations/us-west1/jobs/job01/taskGroups/group01".
Required. Tasks in the group share the same task spec.
task_count int
Number of Tasks in the TaskGroup. Default is 1.
parallelism int
Max number of tasks that can run in parallel. Default to min(task_count, parallel tasks per job limit). See: `Job Limits
Scheduling policy for Tasks in the TaskGroup. The default value is AS_SOON_AS_POSSIBLE.
Compute resource allocation for the TaskGroup. If specified, it overrides resources in Job.
labels MutableMapping[str, str]
Labels for the TaskGroup. Labels could be user provided or system generated. You can assign up to 64 labels. `Google Compute Engine label restrictions
task_environments MutableSequence[]
An array of environment variable mappings, which are passed to Tasks with matching indices. If task_environments is used then task_count should not be specified in the request (and will be ignored). Task count will be the length of task_environments. Tasks get a BATCH_TASK_INDEX and BATCH_TASK_COUNT environment variable, in addition to any environment variables set in task_environments, specifying the number of Tasks in the Task's parent TaskGroup, and the specific Task's index in the TaskGroup (0 through BATCH_TASK_COUNT - 1).
task_count_per_node int
Max number of tasks that can be run on a VM at the same time. If not specified, the system will decide a value based on available compute resources on a VM and task requirements.
require_hosts_file bool
When true, Batch will populate a file with a list of all VMs assigned to the TaskGroup and set the BATCH_HOSTS_FILE environment variable to the path of that file. Defaults to false.
permissive_ssh bool
When true, Batch will configure SSH to allow passwordless login between VMs running the Batch tasks in the same TaskGroup.



LabelsEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

kwargs dict

Keys and values corresponding to the fields of the message.

mapping Union[dict, .Message]

A dictionary or message to be used to determine the values for this message.

ignore_unknown_fields Optional(bool)

If True, do not raise errors for unknown fields. Only applied if mapping is a mapping type or there are keyword parameters.



How Tasks in the TaskGroup should be scheduled relative to each other.

Values: SCHEDULING_POLICY_UNSPECIFIED (0): Unspecified. AS_SOON_AS_POSSIBLE (1): Run Tasks as soon as resources are available.

    Tasks might be executed in parallel depending on parallelism
    and task_count values.
    Run Tasks sequentially with increased task
