How do I completely remove cilium from Ubuntu 18?
hi，you can try check this directory of each node
/etc/cni/net.d/05-cilium.conf
and delete this file:
05-cilium.conf
e.g:
rm /etc/cni/net.d/05-cilium.conf
Finally, restart the flannel daemonsets
kubectl rollout restart daemonsets kube-flannel-ds-amd64 -nkube-system
