fnndsc/swarm repository overview

Swarm

⁠

A swarm cluster manager based on the Python docker API

.. image:: https://travis-ci.org/FNNDSC/swarm.svg?branch=master⁠ :target: https://travis-ci.org/FNNDSC/swarm⁠

The docker image can be run from a swarm manager to schedule a service:

.. code-block:: bash

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock fnndsc/swarm swarm.py -s test -i alpine -c "echo test"

This will schedule the test service that runs command:

.. code-block:: bash

echo test

using the Alpine image

The same thing can be accomplished from Python code:

.. code-block:: python

client = docker.from_env()

⁠'remove' option automatically remove container when finished

byte_str = client.containers.run('fnndsc/swarm', 'swarm.py -s test -i alpine -c "echo test"', volumes={'/var/run/docker.sock': {'bind': '/var/run/docker.sock', 'mode': 'rw'}}, remove=True)

To remove the test service:

.. code-block:: bash

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock fnndsc/swarm swarm.py --remove test

or from Python:

.. code-block:: python

byte_str = client.containers.run('fnndsc/swarm', 'swarm.py --remove test', volumes={'/var/run/docker.sock': {'bind': '/var/run/docker.sock', 'mode': 'rw'}}, remove=True)
