Network lb_web declared as external, but could not be found

I tried installing the haproxy service according to the somewhat sparse instructions. But it's failing on a missing network. Are there missing dependencies to this service? Or are there additional steps I need to go through?

Here's the error output I'm getting

Yes this project is part of http://libre.sh .

We are in the process of migrating to compose v2 for the nicest feature :) Network isolation :)

So this unit file is required somehow https://github.com/indiehosters/libre.sh/blob/master/unit-files/web-net.service

I'll update the README with the instruction if you use this standalone.

Thanks for reporting :)

All the best!

I see. Thanks! :)
