Lab 3.3 why this error when running kubectl exec --it ?

I had the same problem. I used this command
curl $repo/v2/_catalog
{"repositories": []}
and noticed that I had a nothing repository

student@cp: ̃/app1$ sudo podman tag simpleapp $repo/simpleapp
student@cp: ̃/app1$ sudo podman push $repo/simpleapp

I gave a tag and made a push. After that, it started working.

Hi @do.siekierski,

In its current setup, the local repo is not persistent across reboots.
