I’m trying to host a small cluster using kubeadm for practice (1 CPLANE & 1 WORKER). To do this I’ve installed everything (kubeadm, kubelet, kubctl) as per kubernetees official docs. After that i ran
kubeadm init –pod-network-cidr=10.244.0.0/16
(nothing in ip route show was using it)
I check the cluster with kubctl and everything seems fine and running.
After this I enable br_netfilter kernel module (for flannel) and than I apply the latest flannel network map:
kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml
I check again with kubectl get po –all-namespaces and everything looks good… everything is “RUNNING“.
BUT A COUPLE OF MINUTES LATER… it just stops out of nowhere. No more kubectl control no anything. And then it comes back and stops again and keeps doing this…
I dont even know where to start debugging this… any help?**
