Error starting node with forever in docker container

Question

i have a problem when start node with forever in docker container, if i launch manually works, instead the same command in Dockerfile, when build and start the container, exited. The command works in bash:

docker run -it container_name bash forever start -c 'node --harmony' /my/path/app.js

I tried to put command in Dockerfile but the container don't start

CMD forever start -c 'node --harmony' /my/path/app.js

Forever start script.js runs in the background. To run forever in the foreground, try forever script.js.

This starts forever in the foreground, which is what Docker needs. Remember a container is "alive" only as long as the process defined in CMD is up and running. Since forever starts as a daemon, the command itself exits and docker will exit also.

CMD forever -c 'node --harmony' /my/path/app.js

Answer 2

Try using the array syntax:

CMD ["forever", "start", "-c", "node --harmony", "/my/path/app.js"]

Answer 3

I'm now trying to use forever in docker. This works:

CMD ["forever", "src/app.js"]
