Docker problem after machine restart

(Clay Heaton) #1

I had to reboot the machine I have Discourse running on to replace a bad graphics card. However, Discourse won’t restart. When I try ./launcher restart app from within /var/discourse, I see:

clay@machine:/var/discourse$ ./launcher restart app
+ /usr/bin/docker stop -t 10 app

starting up existing container
+ /usr/bin/docker start app
Error response from daemon: Cannot start container app: Bind for failed: port is already allocated
Error: failed to start containers: [app]

When I docker ps -a it looks like:

clay@machine:/var/discourse$ docker ps -a

That sort of makes it look like an old version of Discourse is running?

What’s going on here? How can I get Discourse up and running again? All was fine before I shut down and rebooted.

Ok - I just stopped the “old” discourse and started the proper one with ./launcher start app. What was that ‘old’ discourse and how do I make sure that doesn’t happen again?

Well… it probably won’t. Any real clues we might have had as to why are probably gone by now. If it happens again, that’s when we need to worry.
