When executing step 9 in Exercise 3.1, I am getting the following error when running the command sudo podman build -t simpleapp .
. What can be done about it?

I am running Kubernetes 1.27 on a 2-node cluster with Ubuntu 20.04.5 LTS. I used the Dockerfile included in the course download. The LFD259 lab version is 2023-02-28.

Hi @andrew.nichols,
The lab guide release 2023-02-28 was calling for Kubernetes 1.26.1. Aside from changing the installed Kubernetes version, is there anything else that was modified between lab exercises of Ch 2 and 3?
However, there is a newer course release 2023-05-31, and I would recommend setting up the cluster according to the updated installation and configuration guide.
Regards,
