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:

• deploy.restart_policy.max_attempts
• restart: always

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
