Google Cloud Batch V1 Client - Class TaskGroup (0.17.0)

Reference documentation and code samples for the Google Cloud Batch V1 Client class TaskGroup.

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

Generated from protobuf message google.cloud.batch.v1.TaskGroup

Namespace

Google \ Cloud \ Batch \ V1

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ name string

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".
↳ task_spec Google\Cloud\Batch\V1\TaskSpec

Required. Tasks in the group share the same task spec.
↳ task_count int|string

Number of Tasks in the TaskGroup. Default is 1.
↳ parallelism int|string

Max number of tasks that can run in parallel. Default to min(task_count, parallel tasks per job limit). See: Job Limits. Field parallelism must be 1 if the scheduling_policy is IN_ORDER.
↳ scheduling_policy int

Scheduling policy for Tasks in the TaskGroup. The default value is AS_SOON_AS_POSSIBLE.
↳ task_environments array<Google\Cloud\Batch\V1\Environment>

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|string

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. The host file supports up to 1000 VMs.
↳ permissive_ssh bool

When true, Batch will configure SSH to allow passwordless login between VMs running the Batch tasks in the same TaskGroup.
↳ run_as_non_root bool

Optional. If not set or set to false, Batch uses the root user to execute runnables. If set to true, Batch runs the runnables using a non-root user. Currently, the non-root user Batch used is generated by OS Login. For more information, see About OS Login.
