Cockpit podman module - environment variables?

I’m just getting started with Podman, and trying to use it with Cockpit on Debian or Alma, on both x86_64 and now on a Pi4. The specific container I’m trying to load is Rancher so I can connect to my Harvester cluster, mostly for access control.

I can’t figure out where to put things like:

dash d

dash dash

I can almost get things to work from command line, got another issue to tackle, but I’m not finding the place to put the environment variables, or not understanding the interface.

There is a place to add variables, but it requires a key - value pair. There is also a command box, but that doesn’t seem to pass anything to podman. I tried key=privileged value=true, didn’t go. I tried putting the dash dash privileged in the command box, and again nothing.

Obviously I’m not understanding and I’m doing things wrong
