Build Status

Puppet module for installing, configuring and managing Docker

This module was forked from https://github.com/cristifalcas/puppet-docker and modified to work with the docker package from centos.

Support

This module is currently only for RedHat clones 7.x:

  • Centos 7.0
  • OracleLinux 7.0
  • RedHat 7.0

Usage

The module includes a single class:

include 'docker'

By default the docker daemon will bind to a unix socket at /var/run/docker.sock. This can be changed, as well as binding to a tcp socket if required.

class { 'docker':
  bind_to    => 'tcp://127.0.0.1:4243',
}

If you want to track the latest version you can do so:

class { 'docker':
  version => 'latest',
}

In some cases dns resolution won't work well in the container unless you give a dns server to the docker daemon like this:

class { 'docker':
  dns => '8.8.8.8',
}

The class contains lots of other options, please see the inline code documentation for the full options.

Images

The next step is probably to install a docker image; for this we have a defined type which can be used like so:

docker::image { 'base': }

This is equivalent to running docker pull base. This is downloading a large binary so on first run can take a while. For that reason this define turns off the default 5 minute timeout for exec. Takes an optional parameter for installing image tags that is the equivalent to running docker pull -t="precise" ubuntu:

docker::image { 'ubuntu':
  image_tag => 'precise'
}

Note: images will only install if an image of that name does not already exist.

A images can also be added/build from a dockerfile with the docker_file property, this equivalent to running docker build -t ubuntu - < /tmp/Dockerfile

docker::image { 'ubuntu':
  docker_file => '/tmp/Dockerfile'
}

Images can also be added/build from a directory containing a dockerfile with the docker_dir property, this is equivalent to running docker build -t ubuntu /tmp/ubuntu_image

docker::image { 'ubuntu':
  docker_dir => '/tmp/ubuntu_image'
}

You can also remove images you no longer need with:

docker::image { 'base':
  ensure => 'absent'
}

docker::image { 'ubuntu':
  ensure    => 'absent',
  image_tag => 'precise'
}

If using hiera, there's a docker::images class you can configure, for example:

docker::images:
  ubuntu:
    image_tag: 'precise'

Private registries

By default images will be pushed and pulled from index.docker.io unless you've specified a server. If you have your own private registry without authentication, you can fully qualify your image name. If your private registry requires authentication you may configure a registry:

docker::registry { 'example.docker.io:5000':
  username => 'user',
  password => 'secret',
  email    => 'user@example.com',
}

You can logout of a registry if it is no longer required.

docker::registry { 'example.docker.io:5000':
  ensure => 'absent',
}

If using hiera, there's a docker::registry_auth class you can configure, for example:

docker::registry_auth::registries:
  'example.docker.io:5000':
    username: 'user1'
    password: 'secret'
    email: 'user1@example.io'
