Every time you change configuration and perform “launcher rebuild app” the docker creates the new image that takes 1.5 GB.
I was editing configuration and tuning the installation, and during one of rebuilds it just hanged forever.
After poking around for a while I found that there is no disk space left due to multiple old docker discourse images left form previous rebuilds.
This is rather big. I know, I know, of course you will say it’s “user’s fault”, you should have known about Docker and so on. But we’re installing Discourse and not Docker. It should not be implied that everyone is expert in docker.
The “launcher rebuild app” should include “docker rmi $(docker images -q -f dangling=true)” at the end to clear old images.
Anyway. While it was out of disk space I was editing containers/app.yml and it saved to zero-sized file.
After that I found out about Docker’s images and deleted them.
But file is lost. Is there a way to recover it somehow? I still have my last good image of Discourse running.
