Vanilla Kubernetes

This page is under construction!

Things to be captured here:

1. The kubelet running on worker nodes expects systemd-resolved to be used, whereas Raspberry Pi OS uses dhcpcd instead. As with Rocky Linux users in this kubeadm issue, Raspberry Pi OS required a symbolic link from /etc/resolv.conf to /run/systemd/resolve.
2. The CNI plugin seems to be a requirement. Nodes can be connected as workers, but some pods seem to require Calico or another CNI plugin to be running.
3. Calico needs to be created kubectl -f create not apply, because the annotations for one of its CRDs exceeeds the allowed bytes length. So unfortunately Kustomize can't be used.
4. If running with swap disabled on WSL 2, beware the swapoff -a is a session-only change, not a permanent one, and that there is no /etc/fstab to modify. Instead, use the .wslconfig swap setting to disable swap for WSL 2 VMs.
