I use a combination of netbox for the physical/logical network and server connectivity, and outline for text documentation of the different components.

There's a download link on the page I linked, I don't think they have a container version available, it'll have to be installed manually.

I run mine on a LXC dedicated for that application and time it to boot before the rest of the docker servers.

If you deploy it as a container you could end up with a chicken and egg situation.

This may be overkill for most use cases but you can use jcr.

The best reason to use it in my book is the garbage collection as the official registry doesn't have that feature and can and will bloat over time.

Looks good and I was able to get it on pretty quickly. I was about to post this from the app but saw it's missing the web's markdown shortcuts and image upload option.

Also looking at this post the screenshots are cropped and I didn't see a straight forward way of looking at the whole image.
