Hi, I'm new to Unraid so perhaps I'm missing something here. But I've noticed some extremely strange and frustrating behaviour. Its fairly easy to replicate. Just install a container like e.g. Sonarr, SABnzbd, EmbyServer etc (basically anything), then modify its parameters (e.g. delete some var variables or add some path variables etc) to customise the container to your requirements, then hit Apply and...poof! Your docker container evaporates into the nether, never to be seen again.

It doesn't happen all the time. So sometimes you can change the dockers parameters and apply and it works (i.e. the container gets updated and reboots correctly). Other times though...poof! Gone. Then you have to re-install it again.

This is on a brand new fresh install of 7.3.2 btw.

Because you entered something wrong and the container fails to build.

Can just hit back and correct, or go to apps->previous apps, select reinstall and correct before applying.

You can get back to the template by clicking the "Add Container" button on the docker page, and then selecting the template from the drop down menu.

But yes you are entering something incorrectly thus it cannot build/run and gets orphaned.

You should also tick the "advanced view" toggle on the docker page and make sure you dont have a bunch of orphaned containers taking up space. If you do, click on them and remove them.

I assume I must have I guess. But I honestly don't know what because I made the exact same changes each time and sometimes they would result in the container going poof and sometimes they didn't.

Thanks for the tip. I did that too. Although I was also using the appdata cleanup plus plugin to scan for orphaned entries as well. That being said, it didn't seem to pickup all the orphaned containers. Only the advanced view you mentioned did.

When it fails it'll tell you why in the output, look at it...

They are orphaned images, not containers, i.e. images that have been downloaded but are not currently being used by any container.

That only cares about the appdata folders, not containers or images.
