}
Fields
runnables[]

object (Runnable)

The sequence of scripts or containers to run for this Task. Each Task using this TaskSpec executes its list of runnables in order. The Task succeeds if all of its runnables either exit with a zero status or any that exit with a non-zero status have the ignoreExitStatus flag.

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.
computeResource

object (ComputeResource)

ComputeResource requirements.
maxRunDuration

string (Duration format)

Maximum duration the task should run. The task will be killed and marked as FAILED if over this limit.

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" }.

}
Fields
ignoreExitStatus

boolean

Normally, a non-zero exit status causes the Task to fail. This flag allows execution of other Runnables to continue instead.
background

boolean

This flag allows a Runnable to continue running in the background while the Task executes subsequent Runnables. This is useful to provide services to other Runnables (or to provide debugging support tools like SSH servers).
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".

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.

All locations end up in different regions would cause errors. For example, ["regions/us-central1", "zones/us-central1-a", "zones/us-central1-b", "zones/us-west1-a"] contains 2 regions "us-central1" and "us-west1". An error is expected in this case.

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

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:

NetworkPolicy

NetworkPolicy describes VM instance network configurations.

JSON representation 
{
  "networkInterfaces": [
    {
      object (NetworkInterface)
    }
  ]
}
Fields
networkInterfaces[]

object (NetworkInterface)

Network configurations.

NetworkInterface

A network interface.

JSON representation 
{
  "network": string,
  "subnetwork": string,
  "noExternalIpAddress": boolean
}
Fields
network

string

The URL of an existing network resource. You can specify the network as a full or partial URL.

For example, the following are all valid URLs:
subnetwork

string

The URL of an existing subnetwork resource in the network. You can specify the subnetwork as a full or partial URL.

For example, the following are all valid URLs:
noExternalIpAddress

boolean

Default is false (with an external IP address). Required if no external public IP address is attached to the VM. If no external public IP address, additional configuration is required to allow the VM to access Google Services. See https://cloud.google.com/vpc/docs/configure-private-google-access and https://cloud.google.com/nat/docs/gce-example#create-nat for more information.

PlacementPolicy

PlacementPolicy describes a group placement policy for the VMs controlled by this AllocationPolicy.

JSON representation 
{
  "collocation": string,
  "maxDistance": string
}
Fields
collocation

string

UNSPECIFIED vs. COLLOCATED (default UNSPECIFIED). Use COLLOCATED when you want VMs to be located close to each other for low network latency between the VMs. No placement policy will be generated when collocation is UNSPECIFIED.
maxDistance

string (int64 format)

When specified, causes the job to fail if more than maxDistance logical switches are required between VMs. Batch uses the most compact possible placement of VMs even when maxDistance is not specified. An explicit maxDistance makes that level of compactness a strict requirement. Not yet implemented

JobStatus

Job status.

{
  "state": enum (State),
  "statusEvents": [
    {
      object (StatusEvent)
    }
  ],

      object (TaskGroupStatus)
    },
    ...
  },
  "runDuration": string
}
Fields
state

enum (State)

Job state
statusEvents[]

object (StatusEvent)

Job status events
taskGroups

map (key: string, value: object (TaskGroupStatus))

Aggregated task status for each TaskGroup in the Job. The map key is TaskGroup ID.

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

string (Duration format)

The duration of time that the Job spent in status RUNNING.

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

State

Valid Job states.

Enums
STATE_UNSPECIFIED Job state unspecified.
QUEUED Job is admitted (validated and persisted) and waiting for resources.
SCHEDULED Job is scheduled to run as soon as resource allocation is ready. The resource allocation may happen at a later time but with a high chance to succeed.
RUNNING Resource allocation has been successful. At least one Task in the Job is RUNNING.
SUCCEEDED All Tasks in the Job have finished successfully.
FAILED At least one Task in the Job has failed.
DELETION_IN_PROGRESS The Job will be deleted, but has not been deleted yet. Typically this is because resources used by the Job are still being cleaned up.

TaskGroupStatus

Aggregated task status for a TaskGroup.

JSON representation 
{
  "counts": {
    string: string,
    ...
  },
  "instances": [

Fields
counts

map (key: string, value: string (int64 format))

Count of task in each state in the TaskGroup. The map key is task state name.

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

object (InstanceStatus)

Status of instances allocated for the TaskGroup.

InstanceStatus

Fields
machineType

string

The Compute Engine machine type.
provisioningModel

enum (ProvisioningModel)

LogsPolicy

LogsPolicy describes how outputs from a Job's Tasks (stdout/stderr) will be preserved.

JSON representation 
{
  "destination": enum (Destination),
  "logsPath": string
}
Fields
destination

enum (Destination)

Where logs should be saved.
logsPath

string

The path to which logs are saved when the destination = PATH. This can be a local file path on the VM, or under the mount point of a Persistent Disk or Filestore, or a Cloud Storage path.
