Hi all, new to the forum and to Jekyll.

I am running Jekyll in a Docker container on Ubuntu 22.04 LTS.

Here are my logs:

fatal: not a git repository (or any parent up to mount point /srv)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

Accessing localhost:4000 in Firefox tells me that my browser cannot establish a connection.

Typing in sudo lsof -i :4000 doesn’t bring up anything else on that port.

I can find the IP address of my container, and putting in :4000 gives me an error that my request has timed out.

I can grab the contents of an HTML file and display them in the terminal, so something can see them, it’s just not serving them.

Could you show the Docker command? In particular the -p or --publish flag, which would control how container ports are exposed.
