<p>Execute a command as an ephemeral docker swarm service.
Example use-case - Using Docker Swarm orchestration to make one-time
scripts highly available.</p>
<p>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 <code class="docutils literal notranslate"><span class="pre">AIRFLOW_TMP_DIR</span></code>.</p>
<p>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 <code class="docutils literal notranslate"><span class="pre">docker_conn_id</span></code>.</p>
