How to restart a single container with docker-compose

Question

I have a docker-compose.yml file that contains 4 containers: redis, postgres, api and worker.

During the development of the worker container, I often need to restart it in order to apply changes. Is there any good way to restart a single container (e.g. worker) without restarting the others?

Answer 1

It is very simple: Use the command:

docker-compose restart worker

You can set the time to wait for stop before killing the container (in seconds)

docker-compose restart -t 30 worker

Note that this will restart the container but without rebuilding it. If you want to apply your changes and then restart, take a look at the other answers.
