October 28, 20232 yr I went away for a couple of weeks and during that time my router went down. I suspect it may have been due to my Plex container which started the router to play up when initiating downloads on Android (but not iPhone for some reason). When I got back I reset my router and reset my Unraid. However since rebooting I found all my Dockers are gone with "No Docker containers installed". I tried CA App backup/restore to restore it but that didn't do anything, nor did a reboot. Looking at suggestions on similar issues I have checked that all my drives are mounting and that I have free space. Any other suggestions? unraid-diagnostics-20231028-2003.zip

Sounds as if the docker.img file may have been reset as the diagnostics show it to basically be empty? Simply restoring the appdata will not do anything if the system thinks no dockers are installed - it simply puts the working data back for containers but you still need the containers to be installed. You can reinstall containers with their previous settings intact by using Apps->Previous Apps.

November 22, 2025Nov 22 Late to the party but this just happened to me. Is there a way to build a script that reinstalls these all for me in case it happens again?
