EDIT: this has been released! Next I'm working on adding versions to the images published.

Self hosting support finally!

I have a branch up with self hosting instructions, a Dockerfile, and images published to Github's container registry. If anyone wanted to help test it out it's available on this branch (and the PR).

There are a few configuration options you can change as you wish to disable some of the login page links, change the default instance, and optionally only allow logins to a specific instance.

The published image is just slightly out of date since I changed the publish rules, but at the moment it's only missing some extra validation to check if an instance url is valid.

Let me know if you run into any issues or have anything you think I should change or better explain.
