I have 7.5GB free disk space. I need to rebuild the app container. When running launcher rebuild app it complains that it needs 5.0GB free disk space. I have tried all the docker commands I can think of to free up space, but they all free 0B.
If you have 7.5GB free, runs a rebuild command that downloads the new Discourse image that is over 2.5GB in size, by the time the disk space check comes you will have under 5GB free and fail the check.
Your options are:
Pass --skip-prereqs as a rebuild flag the script. You risk running out disk space and getting your site broken and needing to recover from a backup and a new install.
