what is the point of using pm2 and docker together? : <p>We have been using pm2 quite successfully for running apps on our servers. We are currently moving to docker and we saw <a href="http://pm2.keymetrics.io/docs/usage/docker-pm2-nodejs/" rel="noreferrer">http://pm2.keymetrics.io/docs/usage/docker-pm2-nodejs/</a></p>

<p>But what is the point of actually using both together? Does not docker provide everything pm2 does?</p>
