Hi, I haven’t been using Unraid for very long yet, so I wasn’t aware that the Permission Helper can apparently break Docker.
A bit annoying, in my opinion.
Anyway, could someone tell me what the default permissions and user ownership are for the docker and appdata folders?
Thanks a lot!

The appdata permissions are container specific and controlled by the individual containers so there is no default values.

When you mention the 'docker' folder does that mean you have configured docker to use a folder rather than an image (which is the default)?

Hey itimpi, with 'docker folder' I mean the one configured in docker -> settings -> 'Docker directory'.
I don't remember changing anything during setup except the folders.
Now I set owner of docker files/folders to root, removed containers, removed images and then add the containers again using templates.
It worked so far for all containers I tried except one, before that they were unable to start.

That is not the default as the the default is to use a docker.img file located under /user/system so you changed things from the default. Using a directory is not wrong - just not the default.

That location is where all the binaries for docker containers live. Its contents can easily be recreated if necessary using Apps->Previous Apps to reinstall containers using their previous settings.

Thanks for the 'Previous Apps' hint, I wasn't aware of it.

I don't remember the exact changes I did on default configuration but I changed the docker folder location for sure since I wanted to make sure that it is stored on SSD and not HDD.
However, I decided to disable docker, renamed the docker and appdata folder, enabled docker again and added containers using templates.

After that, I copied old appdata content and adjusted user/group/permissions accordingly.

Everything is running fine again now.

Thanks again.
