I’ve built myself a Redox (Open Source split keyboard).

That one has a number row. Also due to the possibility of programming multiple layers I can hold down a key on the left half, then use the right half as a numpad.

It would also be possible to program it as a toggle button to switch to jumped more, so you don’t have to hold it down, but I prefer not having some kind of invisible state in my keyboard that I have to keep track of.

Do you use podman run followed by podman generate or are you using quadlet?

Quadlet is integrated in podman 4.4 and up and makes it possible to declare your containers in .container files that look like systems unit files and still get the full systems integration: https://www.redhat.com/sysadmin/multi-container-application-podman-quadlet
