rockitthill/rails6-node18 repository overview

The Dockerfile and build configuration can be found here:

https://github.com/rockitthill/docker-rails6-node18⁠

This provides the following:

• A base image based on rockitthill/ruby27multi, which is based on ruby:2.7.8-slim
• Configuration of an /app WORKDIR. This is the path for the Rails application itself.
• Installation of the following:
  • build-essential, curl, git, nano
  • python2 (required by some dependencies)
  • libmariadb-dev (for MariaDB/MySQL)
  • imagemagick (for Carrierwave, Paperclip, or ActiveStorage)
  • node 14.x (LTS)
  • yarn 1.22.4
  • libjemalloc2
• Bundler configuration:
  • Sets bundler global path to /bundle. This can be used as a volume with docker-compose to cache the app's bundle
• Path configuration:
  • Sets /app/bin first for app-specific bin files
  • Sets the appropriate bundle paths for executables provided by gems
• Environment configuration:
  • Sets BINDING to 0.0.0.0 (to allow access to the server outside the container)
  • Sets PORT to 3000 (standard rails server port)
  • Sets EDITOR to nano (easier editing of credentials for us non-vim people)
• Exposes port 3000

It is recommended to use this in conjunction with docker-compose:
