Docker Deployment Helper

Helper gem to create docker containers on a CI server.

Setup

Add the following line to the development group in your Gemfile:

gem 'docker-deploy', require: false, git: 'https://github.com/ad2games/docker-deploy'

What It Does

• Runs bundler-audit
• Checks that puma and rails_migrate_mutex are installed
• Creates a Dockerfile using our Docker-Rails Baseimage
• Downloads GeoIP Database (only when GEOIP_LICENSE_KEY ENV is set)
• Pushes container to private Docker Hub repository tagged with the CI build number

Caching

To achieve faster builds, it pulls the previously pushed image from Docker Hub. If there was no change in gem versions, the whole bundle install step can now be skipped, resulting way faster builds.

Dockerignore

This gems contains a .dockerignore file to exclude everything not needed for production deployment. That includes the git repo, spec files and artifacts left over from the CI test run.

CI Setup

Add the following line to the deployment step of the CI config:

bundle exec rake -r docker-deploy docker:deploy

Make sure to set DOCKER_PASSWORD in the CI ENV.
