Docker Containers Keep Disappearing

Featured Replies

Having a really annoying issue where my Docker containers keep disappearing; it usually happens when Backup & Restore Appdata is running, as I see errors in the backup log. Now my Unraid log is just spammed with this constantly

Usually 2 or 3 random containers are left behind in the Docker screen, but attempting to start them throws an error.

The fix is usually disable docker, tick the "Delete Directory" box, then re-enable Docker. Then I have to use Apps > Previous Apps to reinstall everything. Any ideas on why this keeps happening and how i can stop it?

Jumping in here with my own issue with Docker. Docker disappeared form Unraid's toolbar, I turned it back on and all containers are gone. What hurts the most is the plex app, the amount of work to set this back up to the may I like it, or the way I had it will take 30 - 40 hours. I have skimmed some of this tread and I will go thru a do a through reading, but damn what a kick in the cojones.

Then you're not doing it right. If you go to apps and install all your containers from previous apps there's no need to configure anything (as long as you have the appdata). It will take max 5 min to install everything, and everything will be back as it was.

Thanks Strike. I did find my docker.img it was in a strange place in the files, but I found it.
