This looks pretty neat! Once the FOSS self-hostable version is out I might try it out for my local hackerspace, it seems like it might be useful for those little things that are too small to warrant standing up infrastructure at our small scale.
I am not doing anything fancy for building the dockerfile: https://github.com/windmill-labs/windmill/blob/main/.github/...
Running the docker on the other hand require to pass a few env variables, among them the connection info to a PG instance. It also require to setup an user by editing directly the database and hashing by hand your password which is super inconvenient. I am working right now on making the process easier, did not expect self-host users so early.
At least, that’s always my first reaction when seeing something cool like this.
