uid

string

Output only. A system generated unique ID for the Job.
priority

string (int64 format)

Fields
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".
taskSpec

object (TaskSpec)

Required. Tasks in the group share the same task spec.
taskCount

string (int64 format)

Number of Tasks in the TaskGroup. Default is 1.
parallelism

string (int64 format)

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

enum (SchedulingPolicy)

Scheduling policy for Tasks in the TaskGroup. The default value is AS_SOON_AS_POSSIBLE.
taskEnvironments[]

object (Environment)

An array of environment variable mappings, which are passed to Tasks with matching indices. If taskEnvironments is used then taskCount should not be specified in the request (and will be ignored). Task count will be the length of taskEnvironments.

Tasks get a BATCH_TASK_INDEX and BATCH_TASK_COUNT environment variable, in addition to any environment variables set in taskEnvironments, 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).
taskCountPerNode

string (int64 format)

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.
requireHostsFile

boolean

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.
permissiveSsh

boolean

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

boolean

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.

TaskSpec

Spec of a task

    object (Environment)
  }
}
Fields
runnables[]

object (Runnable)

Required. The sequence of one or more runnables (executable scripts, executable containers, and/or barriers) for each task in this task group to run. Each task runs this list of runnables in order. For a task to succeed, all of its script and container runnables each must meet at least one of the following conditions:

  • The runnable exited with a zero status.
  • The runnable didn't finish, but you enabled its background subfield.
  • The runnable exited with a non-zero status, but you enabled its ignoreExitStatus subfield.
computeResource

object (ComputeResource)

ComputeResource requirements.
maxRunDuration

string (Duration format)

Maximum duration the task should run before being automatically retried (if enabled) or automatically failed. 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.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".
maxRetryCount

integer

Maximum number of retries on failures. The default, 0, which means never retry. The valid value range is [0, 10].
lifecyclePolicies[]

object (LifecyclePolicy)

Lifecycle management schema when any task in a task group is failed. Currently we only support one lifecycle policy. When the lifecycle policy condition is met, the action in the policy will execute. If task execution result does not meet with the defined lifecycle policy, we consider it as the default policy. Default policy means if the exit code is 0, exit task. If task ends with non-zero exit code, retry the task with maxRetryCount.
environments
(deprecated)

map (key: string, value: string)

Deprecated: please use environment(non-plural) instead.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
volumes[]

object (Volume)

Volumes to mount before running Tasks using this TaskSpec.
environment

object (Environment)

Environment variables to set before running the Task.

Runnable

Runnable describes instructions for executing a specific script or container as part of a Task.

JSON representation 
{
  "displayName": string,
  "ignoreExitStatus": boolean,
  "background": boolean,
  "alwaysRun": boolean,
  "environment": {
    object (Environment)
  },
  "timeout": string,
  "labels": {
    string: string,
    ...
  },

  "container": {
    object (Container)
  },
  "script": {
    object (Script)
  },
  "barrier": {
    object (Barrier)
  }
  // End of list of possible types for union field executable.
}
Fields
displayName

string

Optional. DisplayName is an optional field that can be provided by the caller. If provided, it will be used in logs and other outputs to identify the script, making it easier for users to understand the logs. If not provided the index of the runnable will be used for outputs.
ignoreExitStatus

boolean

Normally, a runnable that returns a non-zero exit status fails and causes the task to fail. However, you can set this field to true to allow the task to continue executing its other runnables even if this runnable fails.
background

boolean

Normally, a runnable that doesn't exit causes its task to fail. However, you can set this field to true to configure a background runnable. 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. Even though this is likely to result in a non-zero exit status for the background runnable, these automatic kills are not treated as task failures.
alwaysRun

boolean

By default, after a Runnable fails, no further Runnable are executed. This flag indicates that this Runnable must be run even if the Task has already failed. This is useful for Runnables that copy output files off of the VM or for debugging.

The alwaysRun flag does not override the Task's overall maxRunDuration. If the maxRunDuration has expired then no further Runnables will execute, not even alwaysRun Runnables.
environment

object (Environment)

Environment variables for this Runnable (overrides variables set for the whole Task or TaskGroup).
timeout

string (Duration format)

Timeout for this Runnable.

A duration in seconds with up to nine fractional digits, ending with 's'. Example: "3.5s".
labels

map (key: string, value: string)

Labels for this Runnable.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
Union field executable. Required. The script, container, or barrier for this runnable to execute. executable can be only one of the following:
container

object (Container)

Container runnable.
script

object (Script)

Script runnable.
barrier

object (Barrier)

Barrier runnable.

Container

Container runnable.

JSON representation 
{
  "imageUri": string,
  "commands": [
    string
  ],
  "entrypoint": string,
  "volumes": [
    string
  ],
  "options": string,
  "blockExternalNetwork": boolean,
  "username": string,
  "password": string,
  "enableImageStreaming": boolean
}
Fields
imageUri

string

Required. The URI to pull the container image from.
commands[]

string

Required for some container images. Overrides the CMD specified in the container. If there is an ENTRYPOINT (either in the container image or with the entrypoint field below) then these commands are appended as arguments to the ENTRYPOINT.
entrypoint

string

Required for some container images. Overrides the ENTRYPOINT specified in the container.
volumes[]

string

Volumes to mount (bind mount) from the host machine files or directories into the container, formatted to match --volume option for the docker run command—for example, /foo:/bar or /foo:/bar:ro.

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.
options

string

Required for some container images. Arbitrary additional options to include in the docker run command when running this container—for example, --network host. For the --volume option, use the volumes field for the container.
blockExternalNetwork

boolean

If set to true, external network access to and from container will be blocked, containers that are with blockExternalNetwork as true can still communicate with each other, network cannot be specified in the container.options field.
username

string

Required if the container image is from a private Docker registry. The username to login to the Docker registry that contains the image.

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.

Learn more about Secret Manager and using Secret Manager with Batch.
password

string

Required if the container image is from a private Docker registry. The password to login to the Docker registry that contains the image.

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.

Learn more about Secret Manager and using Secret Manager with Batch.
enableImageStreaming

boolean

Optional. If set to true, this container runnable uses Image streaming.

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 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.

Script

Script runnable.

JSON representation 
{

  // Union field command can be only one of the following:
  "path": string,

  // End of list of possible types for union field command.
}
Fields
Union field command. Required. The source code for this script runnable. command can be only one of the following:
path

string

The path to a script file that is accessible from the host VM(s).

Unless the script file supports the default #!/bin/sh shell interpreter, you must specify an interpreter by including a [shebang line](https://en.wikipedia.org/wiki/Shebang_(Unix) as the first line of the file. For example, to execute the script using bash, include #!/bin/bash as the first line of the file. Alternatively, to execute the script using Python3, include #!/usr/bin/env python3 as the first line of the file.
text

string

The text for a script.

Unless the script text supports the default #!/bin/sh shell interpreter, you must specify an interpreter by including a [shebang line](https://en.wikipedia.org/wiki/Shebang_(Unix) at the beginning of the text. For example, to execute the script using bash, include #!/bin/bash\n at the beginning of the text. Alternatively, to execute the script using Python3, include #!/usr/bin/env python3\n at the beginning of the text.

Barrier

A barrier runnable automatically blocks the execution of subsequent runnables until all the tasks in the task group reach the barrier.

JSON representation 
{
  "name": string
}
Fields
name

string

Barriers are identified by their index in runnable list. Names are not required, but if present should be an identifier.

JSON representation 
{
  "variables": {
    string: string,
    ...
  },
  "secretVariables": {
    string: string,
    ...
  },

    object (KMSEnvMap)
  }
}
Fields
variables

map (key: string, value: string)

secretVariables

map (key: string, value: string)

A map of environment variable names to Secret Manager secret names. The VM will access the named secrets to set the value of each environment variable.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
encryptedVariables

object (KMSEnvMap)

An encrypted JSON dictionary where the key/value pairs correspond to environment variable names and their values.

KMSEnvMap

  "cipherText": string
}
Fields
keyName

string

cipherText

string

The value of the cipherText response from the encrypt method.

ComputeResource

Compute resource requirements.

ComputeResource defines the amount of resources required for each task. Make sure your tasks have enough resources to successfully run. If you also define the types of resources for a job to use with the InstancePolicyOrTemplate field, make sure both fields are compatible with each other.

JSON representation 
{
  "cpuMilli": string,
  "memoryMib": string,
  "bootDiskMib": string
}
Fields
cpuMilli

string (int64 format)

The milliCPU count.

cpuMilli defines the amount of CPU resources per task in milliCPU units. For example, 1000 corresponds to 1 vCPU per task. If undefined, the default value is 2000.

If you also define the VM's machine type using the machineType in InstancePolicy field or inside the instanceTemplate in the 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.
memoryMib

string (int64 format)

Memory in MiB.

memoryMib defines the amount of memory per task in MiB units. If undefined, the default value is 2000. If you also define the VM's machine type using the machineType in InstancePolicy field or inside the instanceTemplate in the InstancePolicyOrTemplate field, make sure the memory 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 8 GiB each, you are recommended to set memoryMib to no more than 8192, or you are recommended to run two tasks on the same VM if you set memoryMib to 4096 or less.
bootDiskMib

string (int64 format)

Extra boot disk size in MiB for each task.

mountOptions[]

string

Mount options vary based on the type of storage volume:

  • For a Cloud Storage bucket, all the mount options provided by the gcsfuse tool are supported.
  • For an existing persistent disk, all mount options provided by the mount command except writing are supported. This is due to restrictions of multi-writer mode.
  • For any other disk or a Network File System (NFS), all the mount options provided by the mount command are supported.

AS_SOON_AS_POSSIBLE

Run Tasks as soon as resources are available.

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

AllocationPolicy

A Job's resource allocation policy describes when, where, and how compute resources should be allocated for the Job.

JSON representation 
{
  "location": {
    object (LocationPolicy)
  },
  "instances": [
    {
      object (InstancePolicyOrTemplate)
    }
  ],

    object (NetworkPolicy)
  },
  "placement": {
    object (PlacementPolicy)
  },
  "tags": [
    string
  ]
}
Fields
location

object (LocationPolicy)

Location where compute resources should be allocated for the Job.
instances[]

object (InstancePolicyOrTemplate)

Describe instances that can be created by this AllocationPolicy. Only instances[0] is supported now.
serviceAccount

object (ServiceAccount)

Defines the service account for Batch-created VMs. If omitted, the default Compute Engine service account is used. Must match the service account specified in any used instance template configured in the Batch job.

Includes the following fields: * email: The service account's email address. If not set, the default Compute Engine service account is used. * scopes: Additional OAuth scopes to grant the service account, beyond the default cloud-platform scope. (list of strings)
labels

map (key: string, value: string)

Custom labels to apply to the job and all the Compute Engine resources that both are created by this allocation policy and support labels.

Use labels to group and describe the resources they are applied to. Batch automatically applies predefined labels and supports multiple labels fields for each job, which each let you apply custom labels to various resources. Label names that start with "goog-" or "google-" are reserved for predefined labels. For more information about labels with Batch, see Organize resources using labels.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
network

object (NetworkPolicy)

The network policy.

If you define an instance template in the InstancePolicyOrTemplate field, Batch will use the network settings in the instance template instead of this field.
placement

object (PlacementPolicy)

The placement policy.
tags[]

string

Optional. Tags applied to the VM instances.

The tags identify valid sources or targets for network firewalls. Each tag must be 1-63 characters long, and comply with RFC1035.

LocationPolicy

JSON representation 
{
  "allowedLocations": [
    string
  ]
}
Fields
allowedLocations[]

string

A list of allowed location names represented by internal URLs.

Each location can be a region or a zone. Only one region or multiple zones in one region is supported now. For example, ["regions/us-central1"] allow VMs in any zones in region us-central1. ["zones/us-central1-a", "zones/us-central1-c"] only allow VMs in zones us-central1-a and us-central1-c.

Mixing locations from different regions would cause errors. For example, ["regions/us-central1", "zones/us-central1-a", "zones/us-central1-b", "zones/us-west1-a"] contains locations from two distinct regions: us-central1 and us-west1. This combination will trigger an error.

InstancePolicyOrTemplate

InstancePolicyOrTemplate lets you define the type of resources to use for this job either with an InstancePolicy or an instance template. If undefined, Batch picks the type of VM to use and doesn't include optional VM resources such as GPUs and extra disks.

JSON representation 
{
  "installGpuDrivers": boolean,
  "installOpsAgent": boolean,
  "blockProjectSshKeys": boolean,

  // Union field policy_template can be only one of the following:
  "policy": {
    object (InstancePolicy)
  },
  "instanceTemplate": string
  // End of list of possible types for union field policy_template.
}
Fields
installGpuDrivers

boolean

Set this field true if you want Batch to help fetch drivers from a third party location and install them for GPUs specified in policy.accelerators or instanceTemplate on your behalf. Default is false.

For Container-Optimized Image cases, Batch will install the accelerator driver following milestones of https://cloud.google.com/container-optimized-os/docs/release-notes. For non Container-Optimized Image cases, following https://github.com/GoogleCloudPlatform/compute-gpu-installation/blob/main/linux/install_gpu_driver.py.
installOpsAgent

boolean

Optional. Set this field true if you want Batch to install Ops Agent on your behalf. Default is false.
blockProjectSshKeys

boolean

Optional. Set this field to true if you want Batch to block project-level SSH keys from accessing this job's VMs. Alternatively, you can configure the job to specify a VM instance template that blocks project-level SSH keys. In either case, Batch blocks project-level SSH keys while creating the VMs for this job.

Batch allows project-level SSH keys for a job's VMs only if all the following are true:

  • This field is undefined or set to false.
  • The job's VM instance template (if any) doesn't block project-level SSH keys.

Notably, you can override this behavior by manually updating a VM to block or allow project-level SSH keys. For more information about blocking project-level SSH keys, see the Compute Engine documentation: https://cloud.google.com/compute/docs/connect/restrict-ssh-keys#block-keys

Union field policy_template.

policy_template can be only one of the following:
policy

object (InstancePolicy)

InstancePolicy.
instanceTemplate

string

Name of an instance template used to create VMs. Named the field as 'instanceTemplate' instead of 'template' to avoid C++ keyword conflict.

Batch only supports global instance templates from the same project as the job. You can specify the global instance template as a full or partial URL.

InstancePolicy

InstancePolicy describes an instance type and resources attached to each VM created by this InstancePolicy.

Non-boot disks to be attached for each VM created by this InstancePolicy. New disks will be deleted when the VM is deleted. A non-boot disk is a disk that can be of a device with a file system or a raw storage drive that is not ready for data storage and accessing.
reservation

string

Optional. If not specified (default), VMs will consume any applicable reservation. If "NO_RESERVATION" is specified, VMs will not consume any reservation. Otherwise, if specified, VMs will consume only the specified reservation.

ProvisioningModel

Compute Engine VM instance provisioning model.

Enums
PROVISIONING_MODEL_UNSPECIFIED Unspecified.
STANDARD Standard VM.
SPOT SPOT VM.
PREEMPTIBLE

Preemptible VM (PVM).

Above SPOT VM is the preferable model for preemptible VM instances: the old preemptible VM model (indicated by this field) is the older model, and has been migrated to use the SPOT model as the underlying technology. This old model will still be supported.

Accelerator

Accelerator describes Compute Engine accelerators to be attached to the VM.

JSON representation 
{
  "type": string,
  "count": string,
  "installGpuDrivers": boolean,
  "driverVersion": string
}
Fields
type

string

The accelerator type. For example, "nvidia-tesla-t4". See gcloud compute accelerator-types list.
count

string (int64 format)

The number of accelerators of this type.
installGpuDrivers
(deprecated)

boolean

Deprecated: please use instances[0].install_gpu_drivers instead.
driverVersion

string

Optional. The NVIDIA GPU driver version that should be installed for this type.

You can define the specific driver version such as "470.103.01", following the driver version requirements in https://cloud.google.com/compute/docs/gpus/install-drivers-gpu#minimum-driver. Batch will install the specific accelerator driver if qualified.

Disk

A new persistent disk or a local ssd. A VM can only have one local SSD setting but multiple local SSD partitions. See https://cloud.google.com/compute/docs/disks#pdspecs and https://cloud.google.com/compute/docs/disks#localssds.

JSON representation 
{
  "type": string,
  "sizeGb": string,
  "diskInterface": string,

  // Union field data_source can be only one of the following:
  "image": string,
  "snapshot": string
  // End of list of possible types for union field data_source.
}
Fields
type

string

Disk type as shown in gcloud compute disk-types list. For example, local SSD uses type "local-ssd". Persistent disks and boot disks use "pd-balanced", "pd-extreme", "pd-ssd" or "pd-standard". If not specified, "pd-standard" will be used as the default type for non-boot disks, "pd-balanced" will be used as the default type for boot disks.
sizeGb

string (int64 format)

Disk size in GB.

Non-Boot Disk: If the type specifies a persistent disk, this field is ignored if data_source is set as image or snapshot. 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 bootDiskMib field in task spec's computeResource 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.
diskInterface

string

Local SSDs are available through both "SCSI" and "NVMe" interfaces. If not indicated, "NVMe" will be the default one for local ssds. This field is ignored for persistent disks as the interface is chosen automatically. See https://cloud.google.com/compute/docs/disks/persistent-disks#choose_an_interface.
Union field data_source. A data source from which a PD will be created. data_source can be only one of the following:
image

string

URL for a VM image to use as the data source for this disk. For example, the following are all valid URLs:

  • Specify the image by its family name: projects/{project}/global/images/family/{image_family}
  • Specify the image version: projects/{project}/global/images/{imageVersion}

You can also use Batch customized image in short names. The following image values are supported for a boot disk:

  • batch-debian: use Batch Debian images.
  • batch-cos: use Batch Container-Optimized images.
  • batch-hpc-rocky: use Batch HPC Rocky Linux images.
snapshot
