nibbled is a Gopher daemon.
This is yet another COVID-19 project, reviving an old project I'd intended on starting when I first started using Go in anger.
It has partial gophermap support, but only supports a subset of Gophernicus's functionality. It supports #, ., and *.
By default, nibbled will serve from /srv/gopher. The most straightforward way to get up and running is to mount a local directory at that path:
docker run -d -p 70:70 -v /path/to/your/gopherhole:/srv/gopher ghcr.io/kgaughan/nibbled:latest
