A cookbook for pulling docker images from dockerhub and spinning up containers from node attributes (including host integration).
Set your dockerhub username, password and email by overriding:
node['docker_username'] = your_username node['docker_password'] = your_password node['docker_email'] = your email
Using something like chef-credentials will allow you to encrypt and store these attributes within an encrypted data bag (so they can be safely commit to your source control).
Define the images you want to be installed and spun up as containers on the node:
node['docker_images'] = [{'name' => 'nginx', 'port' => '80:80'}]
Now include the 'docker-images' cookbook as part of your run_list for a node, and when you cook the server it will pull down the latest version of the docker image, create a container (with in the example above port 80 mapped to port 80) and create the necessary init scripts to ensure your container spins up on boot.
Librarian-Chef is a bundler for your chef cookbooks. To install Librarian-Chef:
cd chef-repo
gem install librarian
librarian-chef init
To use credentials:
echo "cookbook 'docker-images', git: 'git://github.com/cfreeman/chef-docker-images.git'" >> Cheffile
Pulls docker images and creates matching containers from metadata specified in node attributes
