Newbie: Can't get apps to run after restart (using rails, postgre, docker and dokku)
Hi, I deployed my app to droplet with rails, postgre, docker and dokku.
All was running smoothly, until I restarted the server today and I got into two problems:
1) One rails app said it was already running. The app said, there was /app/tmp/pids/server.pid file but I couldn't find the server.pid file in the image though using
find / | grep 'server.pid'
2) Other app couldn't connect to the postgres, which after an inspection shows that is running on a different port. I tried re-deploying, re-establishing the postgre link through dokku and nothing happened, same error.
Eventually, I restarted the app2 with bad postgre through docker, that made things even worse and I have now two apps that won't start.
Also I am trying to figure out why the hell I have unnamed images which seem to contain the Rails app and database, even tried to erased them and start fresh, but the deeper I dig, the more weird problems I get.
For instance removing the image says a different image is not there:

I seem to run into some newbie stuff I can't even google answers for so any help is greatly appreciated.
