docker-ruby-pair-programming

Docker image for pair programing on ruby applications

Building the image: Pass the user to the image so user inside the image has the same id as the outside user and share permissions

docker build --build-arg USER_UID=$(id -u) --build-arg USER_GID=$(id -g) --tag barrerajl/ruby-pair-programming

Usage:

#Rails example
  ruby-application:
    image: barrerajl/ruby-pair-programming #image name at build time
    ports:
      - "31022:22" #ssh for tmux and so on...
      - "33000:3000" #ports to publish
    environment:
      AUTHORIZED_GH_USERS: barrerajl,barrerajl,barrerajl #github users to authorize comma separated a,b,c
    volumes:
      - './rails_app:/home/developer/app' #map actual directory outside for keeping the code
      - 'vim_sessions:/home/developer/.homesick/repos/vim-dot-files/home/.vim/sessions'

volumes:
  vim_sessions:  {} #volume to save different vim sessions

How to connect to the image: Use -A to use the agent forwarding capabilities

ssh -A -p 31022 developer@mydockerhost
