Welcome to the Linux Foundation Forum!

I am struggling getting past step 11 of lab 3.2

After I reboot both the cp and worker node in step 10, I am unable to connect to my repo from my cp. I also find kubectl has stopped working. I have a snapshot I can revert to that proves this command was working before step 10.

ryan@k8slab1:~$ curl $repo/v2/_catalog
^C
ryan@k8slab1:~$ echo $repo
10.97.40.62:5000
ryan@k8slab1:~$ kubectl get pods
The connection to the server 172.17.12.202:6443 was refused - did you specify the right host or port?

    I find it actually starts to fail if I reboot after step 4.

    ryan@k8slab1:~$ kubectl version
    Client Version: v1.34.1
    Kustomize Version: v5.7.1

    If I rebuild config.toml, I get kubectl working again. But his of course removes changes your script made.

    sudo containerd config default | sudo tee /etc/containerd/config.toml

    Hi @rhopping,

    Try skipping step 10. There is a chance the config is persisted without reboot.
