pm2-docker PM2 logs should be optional or disabled

[t3h2mas]

What's going wrong?

pm2-docker logs to the ~/.pm2/logs/ directory using the files app-error-0.log and app-out-0.log
Inside of a Docker container, it makes sense to leave log drivers, and more importantly log rotation to the Docker engine.

This means that even if someone uses log rotation at the docker level, PM2 log management would have to be configured within the container

Suggested fix:
Either default to
--output NULL
--error NULL

Or support the arguments in pm2-docker, and make a note somewhere in documentation

How could we reproduce this issue?

Run a docker container using pm2-docker. Be sure your app logs to stdout.
Exec into the running container: docker exec -it <CONTAINERNAME> bash
Change into the logs directory: cd ~/.pm2/logs
Check file size: du -h *

Seeing anything but 0's there means that PM2 will continue to use up disk space from within the container

@t3h2mas are you using Linux ?
cause in my case no log file are creating by pm2-docker command..
but if i do pm2-start app.js then log files are creating in given path (im using windows 10)

Fixed on recently published pm2 (2.7.0):

$ npm install pm2@latest -g
$ pm2 update

Now pm2-docker does not write logs by default

Let me know if there is any issue
