Docker Compose+Swarm using dind

===============================

A sandboxed swarm cluster.

.. contents::

    :backlinks: none

Setup

-----

.. code:: sh

    docker-compose up -d

    eval "$(./bin/env)"

Running ``docker`` or ``docker-compose`` commands in the shell will run them

on the ``swarm`` sandbox.

Features

--------

Scale the number of swarm slaves or masters

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To increase or decrease the number of swarm slaves, run ``docker-compose scale``.

They will auto-join the cluster.

.. code:: sh

    docker-compose scale swarm.slave=3

To scale the number of master replicas:

.. code:: sh

    docker-compose scale swarm.master=3

Discovery Backends

------------------

The default discovery backend is ``zookeeper``. To use ``etcd`` or ``consul``

as the discovery backends you can run ``docker-compose`` with one of the extra

``with-*.yml`` files.

.. note::

   This requires features only available in the (upcoming) docker-compose 1.5

   release.

.. code:: sh

    docker-compose -f docker-compose.yml -f with-etcd.yml up

Troubleshooting

---------------

Docker-in-docker and storage drivers

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the ``swarm.slave`` containers fail to start with an error about

``Error starting daemon: error initializing graphdriver: driver not supported``

you can adjust the storage in ``docker-compose.yml`` with the ``DOCKER_ARGS``

environment variable.

The default storage driver is ``overlay``, but it may not be available on your

kernel.
