I am a total newbie on docker and 'nix
I managed to install Discourse at Linode using the “under 30 minutes” instructions and ran it for a few weeks.
I was able to upgrade a few times using the Upgrade link inside Discourse.
Recently however the upgrade message mentioned something about upgrading Docker and then left a message for me to do something by SSH
Unfortunately I did not save what it said.
I connected into Linnode’s Graphical Web Console and Shut down the Virtual Machine
When I started the VM again I got the “Site cannot be reached” message trying to go to my Discourse site.
Then I ran ./launcher rebuild app
This did a lot of things
now if I run docker ps -a I see only one container with image name local_discourse/app
When I try to
docker run local_discourse/app I get a message ‘undefined method’
What should I do?
