The UI looks pretty neat, but the install instructions are essentially "curl {url}/install.sh | bash -", which is kind of icky and runs a bunch of sudo commands. Since you're using Docker anyway, why not provide human-readable instructions?
Or, alternately, separate the config process from the install process. I'd be much more comfortable running config commands from a script inside the docker container, or as a first-run setup UI, or as a simple .yaml config.
It does look like something I'd like to try out later, though. Either after the install process is cleaned up a bit, or once I have time to read through the whole install.sh script.
Edit: In case it matters, my personal preference is to install things as linux packages instead of Docker, but I understand that this is a stretch for early-access software.
