Use Chef

Note: Please note this is a community contributed installation path.

Requirements

To use this guide you'll need a working installation of Chef. This cookbook supports a variety of operating systems.

Installation

The cookbook is available on the Chef Supermarket and can be installed using your favorite cookbook dependency manager.

The source can be found on GitHub.

Usage

  • Add depends 'docker', '~> 2.0' to your cookbook's metadata.rb
  • Use resources shipped in cookbook in a recipe, the same way you'd use core Chef resources (file, template, directory, package, etc).
docker_service 'default' do
  action [:create, :start]
end

docker_image 'busybox' do
  action :pull
end

docker_container 'an echo server' do
  repo 'busybox'
  port '1234:1234'
  command "nc -ll -p 1234 -e /bin/cat"
end

Getting started

Here's a quick example of pulling the latest image and running a container with exposed ports.

# Pull latest image
docker_image 'nginx' do
  tag 'latest'
  action :pull
end

# Run container exposing ports
docker_container 'my_nginx' do
  repo 'nginx'
  tag 'latest'
  port '80:80'
  binds [ '/some/local/files/:/etc/nginx/conf.d' ]
  host_name 'www'
  domain_name 'computers.biz'
  env 'FOO=bar'
  subscribes :redeploy, 'docker_image[nginx]'
end
