Docker Compose[1] is a tool available since 2014 for defining and running multi-container Docker applications.

Rules are defined in docker-compose.yml and executed by running docker-compose up.

docker-compose allows to define start order dependencies between containers.

For reference of valid options for docker compose check: https://docs.docker.com/compose/compose-file/

Installation

  • brew install docker-compose

Basic commands

  • docker-compose -h (for list of commands and options)
  • docker-compose up
  • docker-compose up -d
-d daemon
  • Start your containers with a command line variable: YOUR_VARIABLE=YOUR_VALUE docker-compose up[2]


  • docker-compose -p NAME --project-name

Logs:

  • docker-compose logs View output from containers
  • docker-compose logs -f View output from containers
  • docker-compose pull SERVICE_NAME or docker-compose pull
