Docker Compose file — limit restart count

Question

In my docker-compose.yaml I am saying to alway restart app service

  app:
    build: .
    image: app:latest
    ports:
      - 3000:3000
    restart: always
    volumes:
     - "./:/usr/src/app"

This works, but in case of permanent error (eg. server is running some other way, …), the service keeps trying to start. Is there way to limit number of attempts to restart the service?

Here is a demo code, which I created to take us on same page:

You can find the answer in the docker compose reference description here:

https://docs.docker.com/compose/compose-file/

You can apply a condition to the restart block inside of the compose file. In your case something like:

restart_policy:   
  condition: on-failure   
  max-attempts: 3

It seems to me what you refer to, is for docker stacks. I'll try it at home, but I think this is ignored by docker compose. – Mailo Světel Apr 08 '20 at 17:45
@MailoSvětel Did you try the solution? – OYPS Apr 11 '20 at 07:44
Sorry for the delay, I was on other stuff. It works just as I suspected. Check the updated question for links to demo code – Mailo Světel Apr 12 '20 at 12:39
