I use podman desktop on my mac but do most things from the command line.
Consider this simple container file below. If I run from the mac command
line "podman run -it test" it successfully launches it on the podman
machine (a virtual fedora instance). From within container space if I do
"id" I see userid 2000 as expected. If I ssh into the podman machine, and
look at the uid of the running container it is also 2000 on the host fedora
virtual machine as well. This is different than how it behaves if I run
the same "podman run -it test" on a native RHEL9 machine. I can also log
into it and see it is uid 2000 from within container but when I look a the
native RHEL9 process running the container it has a uid of 526287. Why is
the behavior different? Is the remote podman client on the mac launching
things differently?
Thanks, Ed
