Bases: airflow.models.BaseOperator

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 | None) – DEPRECATED, use container_overrides instead with the same value.

• container_overrides (dict | None) – the containerOverrides parameter for boto3 (templated)

• node_overrides (dict | None) – the nodeOverrides parameter for boto3 (templated)

• share_identifier (str | None) – The share identifier for the job. Don’t specify this parameter if the job queue doesn’t have a scheduling policy.

• scheduling_priority_override (int | None) – The scheduling priority for the job. Jobs with a higher scheduling priority are scheduled before jobs with a lower scheduling priority. This overrides any scheduling priority in the job definition

• 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

• deferrable (bool) – Run operator in the deferrable mode.

• awslogs_enabled (bool) – Specifies whether logs from CloudWatch should be printed or not, False. If it is an array job, only the logs of the first task will be printed.

• awslogs_fetch_interval (datetime.timedelta) – The interval with which cloudwatch logs are to be fetched, 30 sec.

• poll_interval (int) – (Deferrable mode only) Time in seconds to wait between polling.

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”)

hook()

execute(context)

Submit and monitor an AWS Batch job.

Raises

AirflowException

execute_complete(context, event=None)

on_kill()

Override this method to clean up 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)

Submit an AWS Batch job.

Raises

AirflowException

monitor_job(context)

Monitor an AWS Batch job.

This can raise an exception or an AirflowTaskTimeout if the task was created with execution_timeout.

class airflow.providers.amazon.aws.operators.batch.BatchCreateComputeEnvironmentOperator(compute_environment_name, environment_type, state, compute_resources, unmanaged_v_cpus=None, service_role=None, tags=None, poll_interval=30, max_retries=None, aws_conn_id=None, region_name=None, deferrable=conf.getboolean('operators', 'default_deferrable', fallback=False), **kwargs)

Bases: airflow.models.BaseOperator

Create an AWS Batch compute environment.

For more information on how to use this operator, take a look at the guide: Create an AWS Batch compute environment

Parameters

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

• environment_type (str) – Type of the compute-environment.

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

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

• unmanaged_v_cpus (int | None) – 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) – IAM role that allows Batch to make calls to other AWS services on your behalf (templated).

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

• poll_interval (int) – How long to wait in seconds between 2 polls at the environment status. Only useful when deferrable is True.

• max_retries (int | None) – How many times to poll for the environment status. Only useful when deferrable is True.

• 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. Overrides the region_name in connection if provided.

• deferrable (bool) – If True, the operator will wait asynchronously for the environment to be created. This mode requires aiobotocore module to be installed. (default: False)
