Docker Compose Cheatsheet

N. P. O'Donnell, 2020

Facts about Docker Compose

  • Docker Compose is not a part of Docker
  • Consists of 2 parts: CLI and .yaml files
  • Deals in services (a service is comprised of several containers)
  • Default compose file is docker-compose.yml but any filename may be used
  • First line of compose file is version, but compose file version does not correspond to docker compose version.
