My guess is that your cluster is unstable due to misconfiguration of containerd. You say you’re following the video; it would be better to follow the tutorial in the course repo, which is easier to get right. Look at the tasks in the Node Setup page and do them carefully, making sure that the you can use kubectl before you go on (try kubectl get nodes, which will respond even before you install weave) to setting up weave.
