Installation

• Optionally, install docker-ssh-agent-forward if you need to install private gems or deploy via SSH.

• Copy the script bundle-package-all-with-docker into your path:

  curl -sL https://github.com/djmaze/rails-dev-env-with-docker-and-compose/raw/master/bundle-package-all-with-docker | sudo tee /usr/local/bin/bundle-package-all-with-docker 1>/dev/null
  sudo chmod +x /usr/local/bin/bundle-package-all-with-docker
  

Getting started with an existing app

(Note: You have to prefix all commands with sudo -E if you need to run Docker as root).

• Use the ruby base image (with the version needed) in your Dockerfile.

• In your project directory, fetch all gems one-time:

    bundle-package-all-with-docker
  

• Then do a docker build as usual.

You need to re-run bundle-package-all-with-docker when your Gemfile is changed.

Setting up a new rails app

In a new directory, run:

touch Gemfile
bundle-package-all-with-docker
gem install rails
rails new
