| |
| .. py:class:: DockerSwarmOperator(image, *args, **kwargs) |
| |
| Bases: :class:`airflow.operators.docker_operator.DockerOperator` |
| |
| Execute a command as an ephemeral docker swarm service. |
| Example use-case - Using Docker Swarm orchestration to make one-time |
| scripts highly available. |
| |
| A temporary directory is created on the host and |
| mounted into a container to allow storing files |
| that together exceed the default disk size of 10GB in a container. |
| The path to the mounted directory can be accessed |
| via the environment variable ``AIRFLOW_TMP_DIR``. |
| |
| If a login to a private registry is required prior to pulling the image, a |
| Docker connection needs to be configured in Airflow and the connection ID |
| be provided with the parameter ``docker_conn_id``. |
| |
| :param image: Docker image from which to create the container. |
| If image tag is omitted, "latest" will be used. |
| :type image: str |
| :param api_version: Remote API version. Set to ``auto`` to automatically |
| detect the server's version. |
| :type api_version: str |
| :param auto_remove: Auto-removal of the container on daemon side when the |
| container's process exits. |
| The default is False. |
| :type auto_remove: bool |
| :param command: Command to be run in the container. (templated) |
| :type command: str or list |
| :param docker_url: URL of the host running the docker daemon. |
| Default is unix://var/run/docker.sock |
| :type docker_url: str |
| :param environment: Environment variables to set in the container. (templated) |
| :type environment: dict |
| :param force_pull: Pull the docker image on every run. Default is False. |
| :type force_pull: bool |
| :param mem_limit: Maximum amount of memory the container can use. |
| Either a float value, which represents the limit in bytes, |
| or a string like ``128m`` or ``1g``. |
| :type mem_limit: float or str |
| :param tls_ca_cert: Path to a PEM-encoded certificate authority |
| to secure the docker connection. |
| :type tls_ca_cert: str |
| :param tls_client_cert: Path to the PEM-encoded certificate |
| used to authenticate docker client. |
| :type tls_client_cert: str |
| :param tls_client_key: Path to the PEM-encoded key used to authenticate docker client. |
| :type tls_client_key: str |
| :param tls_hostname: Hostname to match against |
| the docker server certificate or False to disable the check. |
| :type tls_hostname: str or bool |
| :param tls_ssl_version: Version of SSL to use when communicating with docker daemon. |
| :type tls_ssl_version: str |
| :param tmp_dir: Mount point inside the container to |
| a temporary directory created on the host by the operator. |
| The path is also made available via the environment variable |
| ``AIRFLOW_TMP_DIR`` inside the container. |
| :type tmp_dir: str |
| :param user: Default user inside the docker container. |
| :type user: int or str |
| :param docker_conn_id: ID of the Airflow connection to use |
| :type docker_conn_id: str |
