Did they release the controller setup?

Have you tried portainer?

I don't know if they fixed it, I hope so, but not long ago there was a very dangerous vulnerability that allowed an attacker to bring able to access the master password.

I was using it long time ago, then I discovered Bitwarden and I'm really happy with it. I suggest you to have a look, in terms of UI is better and can be self hosted too.

Make sure to have enough time because you won't see the sun for a while
