An Alpine Linux based Docker image for the Gophernicus Gopher server.
Do you just want to run a simple Gopher service? Do you not want to mess the hassle of setting up old-school inetd/xinetd/systemd sockets/etc? Are you already running all your other services as containers? Me too!
This image runs Gophernicus via xinetd on an Alpine Linux base for a Docker image that weighs in at just a smidge under 7MB. Set your hostname, map your favorite volume at /var/gopher, bind port 70 and go!
ex:
docker run --name gophernicus \
--hostname <your gopher hostname> \
-p 70:70 \
-v <your gopher root>:/var/gopher \
joshkaiju/gophernicus
Set the hostname of your container to the FQDN of your gopher site to ensure that links work correctly.
The majority of Gophernicus settings can be configured via environment variables. All Gophernicus defaults apply except where otherwise noted.
