adamstrickland/rails repository overview

⁠Info:

• Imports adamstrickland/ruby⁠
• Installs NodeJS, procps, bison
• Exposes port 3000
• Sets bundle install --system --without test development && PORT=3000 foreman start as the CMD

⁠To use:

• In the root of your Rails app, add a Dockerfile and a Procfile

• Define your runtime processes in the Procfile:

  web: bundle exec rackup -p $PORT

  or something similar

• In your Dockerfile:

  RUN apt-get install -y libsqlite3-dev sqlite3   # <= change/add dependencies as appropriate
  ADD . /var/application
  WORKDIR /var/application
  

  Copy

• From $RAILS_ROOT:

  docker build -t your_app_tag && docker run -p 3000:3000 -d your_app_tag

  This will run bundle install and startup the application according to the Procfile. You should be able to curl it: curl $HOST:3000 | grep Getting

  NOTE: if on OSX using boot2docker (which is what I do), $HOST in will need to reference the boot2docker instance; by default this is 192.168.59.103, not localhost.
