Restart NodeJS app running in docker container

I have a nodejs app running in several docker containers in production mode. One of them is running backend app.

I want to know how to force this container to restart on some event programatically( for example system time has changed)? I need the same behaviour just as I would type ‘docker restart container-name’. The docker restart policy is set to always.

Thank you,

Tried process.exit() but not sure why docker daemon is not restarting

Solution

  • You have to run your container with this command:

     docker run -d --restart unless-stopped [Container_name]

    with unless-stopped flag your container will restart automatically unless you stop it manually.

    With this approach you can stop your Node js process using process.exit() and your container will restart.
