Alrighty, here's what I've got

FROM golang:1.21

WORKDIR /app
COPY . ./

RUN go mod download
RUN CGO_ENABLED=0 GOOS=linux go build -buildvcs=false .

EXPOSE 4000

ENTRYPOINT ["/app/hex"]
#CMD ["-hb","https://lemmygrad.ml/api/v3/"] #Optional

basically just clone the repo, cd into it, create a file with the above lines in it called Dockerfile (uncomment and change the instance base URL if you want to), and then run some docker commands like this:

sudo docker build --tag diethex .
sudo docker run -d --publish 4000:4000 diethex

Then you should be running on port 4000 to test out. Then map the port however you need it and pipe a subdomain to it using nginx as needed.

Oh and if you want to change the title, remove the taglines, etc, you'll need to edit the page templates in files/... It should be pretty straightforward to just change the title/header and remove the MOTD/taglines. I did it but only for the main page.

Okay I got bored and decided to play with it. I got it running in a docker pretty easily, going to see how well pointing it at other instances works now. Will post Dockerfile and results.

Edit: okay, it works fine pointed at a non-hexbear instance (and you don't need to edit code, it's a command line flag.) Buuuut, the title still says diet hexbear and the taglines are all still hexbear's

You could do it but you'd have to be willing to do some of the docker stuff yourself. it shouldn't be too hard, just writing a dockerfile that installs the deps and the compiled app and runs it. OP is running it as an openrc service so that doesn't (likely) help you. some hexbear specific stuff is hardcoded but not a ton I don't think.

And of course you'd have to change the baseurl in hb/hb.go
