Execute a job on AWS Batch

For more information on how to use this operator, take a look at the guide: Submit a new AWS Batch job

Parameters

  • job_name (str) – the name for the job that will run on AWS Batch (templated)

  • job_definition (str) – the job definition name on AWS Batch

  • job_queue (str) – the queue name on AWS Batch

  • overrides (dict) – the containerOverrides parameter for boto3 (templated)

  • array_properties (dict | None) – the arrayProperties parameter for boto3

  • parameters (dict | None) – the parameters for boto3 (templated)

  • job_id (str | None) – the job ID, usually unknown (None) until the submit_job operation gets the jobId defined by AWS Batch

  • waiters (Any | None) – an BatchWaiters object (see note below); if None, polling is used with max_retries and status_retries.

  • max_retries (int | None) – exponential back-off retries, 4200 = 48 hours; polling is only used when waiters is None

  • status_retries (int | None) – number of HTTP retries to get job status, 10; polling is only used when waiters is None

  • aws_conn_id (str | None) – connection id of AWS credentials / region name. If None, credential boto3 strategy will be used.

  • region_name (str | None) – region name to use in AWS Hook. Override the region_name in connection (if provided)

  • tags (dict | None) – collection of tags to apply to the AWS Batch job submission if None, no tags are submitted

Note

Any custom waiters must return a waiter for these calls: .. code-block:: python

waiter = waiters.get_waiter(“JobExists”) waiter = waiters.get_waiter(“JobRunning”) waiter = waiters.get_waiter(“JobComplete”)

Submit and monitor an AWS Batch job

Raises

AirflowException

on_kill()[source]

Override this method to cleanup subprocesses when a task instance gets killed. Any use of the threading, subprocess or multiprocessing module within an operator needs to be cleaned up or it will leave ghost processes behind.

submit_job(context)[source]

Submit an AWS Batch job

Raises

AirflowException

monitor_job(context)[source]

Monitor an AWS Batch job monitor_job can raise an exception or an AirflowTaskTimeout can be raised if execution_timeout is given while creating the task. These exceptions should be handled in taskinstance.py instead of here like it was previously done

Raises

AirflowException

Parameters

  • compute_environment_name (str) – the name of the AWS batch compute environment (templated)

  • environment_type (str) – the type of the compute-environment

  • state (str) – the state of the compute-environment

  • compute_resources (dict) – details about the resources managed by the compute-environment (templated). See more details here https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/batch.html#Batch.Client.create_compute_environment

  • unmanaged_v_cpus (int | None) – the maximum number of vCPU for an unmanaged compute environment. This parameter is only supported when the type parameter is set to UNMANAGED.

  • service_role (str | None) – the IAM role that allows Batch to make calls to other AWS services on your behalf (templated)

  • tags (dict | None) – the tags that you apply to the compute-environment to help you categorize and organize your resources

  • max_retries (int | None) – exponential back-off retries, 4200 = 48 hours; polling is only used when waiters is None

  • status_retries (int | None) – number of HTTP retries to get job status, 10; polling is only used when waiters is None

  • aws_conn_id (str | None) – connection id of AWS credentials / region name. If None, credential boto3 strategy will be used.

  • region_name (str | None) – region name to use in AWS Hook. Override the region_name in connection (if provided)
