Docker

• Install from the Setup section
• Usage

  # clean build (remove `--no-cache` for speed)
  docker-compose build --no-cache --parallel
  
  # start container
  docker-compose up --remove-orphans -d
  
  # exec into container
  docker attach hello
  
  # run command inside container
  python hello.py
  
  # stop container
  docker-compose stop
  
  # destroy container and network
  docker-compose down

Debugging

• Watch logs in real-time: docker-compose logs -tf --tail="50" hello
• Check exit code

  $ docker-compose ps
  Name                          Command               State    Ports
