Docker Tip #23: Docker Compose vs Docker Stack
Docker Compose and Docker Stack can both be controlled by a docker-compose.yml file. Learn the differences between them.
Docker Compose is an official tool that helps you manage your Docker containers by letting you define everything through a
It just so happens both Docker Compose and the
docker stack command support the same
docker-compose.yml file with slightly different features.
In some cases, certain features that only work with
docker stack are ignored by Docker Compose, and likewise, unsupported features of Docker Compose are ignored by the
docker stack command.
For example, the
deploy property is ignored by Docker Compose and
depends_on is ignored by
docker stack. There are other differences too. You can find them out by checking out the official Compose file reference. It will call out Compose or Stack specific properties.
I really like what Docker did here. This allows you to define a single
docker-compose.yml that works for both Docker Compose and
docker stack which is a nice quality of life improvement if you happen to use Docker Compose in development and Docker Swarm in production.
