Configuration

Drone is configured by setting certain ENV variables in the agent/server containers.

For Drone ENV config settings see:

With this cookbook you can inject ENV variables to your Drone agent/server containers by using node['drone']['agent']['config'] and node['drone']['server']['config']. The keys after config are the ENV variable names and the value you set is the value to assign the ENV variable.

You can find examples of this in use in the .kitchen.yml

Secrets With Chef-Vault

This cookbook supports using secrets from chef-vault. The vault bag to use is controlled by node['drone']['vault']['bag']. Vault items that are loaded are controlled by the default['drone']['agent']['vault']['items'] and default['drone']['server']['vault']['items'] attributes.

HTTPS Config

Drone has the ability to terminate SSL connections. This cookbook doesn't do this for you but supports being able to do it.

  1. Add your cert and private key to the host
  1. Expose the certificates to the Drone container using node['drone']['server']['volumes']
node['drone']['server']['volumes'] = [
  "/var/lib/drone:/var/lib/drone",
  "/var/run/docker.sock:/var/run/docker.sock",
  "/etc/ssl/certs/drone.pem:/etc/ssl/certs/drone.pem",
  "/etc/ssl/private/drone.key:/etc/ssl/private/drone.key"
]
  1. Configure Drone to use the cert/key pair
node['drone']['config']['drone_server_cert'] = '/etc/ssl/certs/drone.pem'
node['drone']['config']['drone_server_key'] = '/etc/ssl/private/drone.key'
  1. Expose Drone service via host port 443
node['drone']['server']['port'] = '443:8000'

Docker

See attributes/docker.rb for more options.

Testing

  • Linting - Rubocop and Foodcritic
  • Spec - ChefSpec
  • Integration - Test Kitchen

Testing requires ChefDK be installed using it's native gems.

gem install docker-api
foodcritic -f any -X spec .
rubocop
rspec --color --format progress

If you run into issues testing please first remove any additional gems you may have installed into your ChefDK environment. Extra gems can be found and removed at ~/.chefdk/gem.
