Why does Kubernetes TCP networking require opened UDP ports?
I am running a self-managed Microk8s Kubernetes with Calico CNI. I have recently added a new node into the cluster and I have been seeing some network problems between pods on particular nodes.
k8s : Calico node is not coming up
I am trying to bring up k8s cluster with calico. Calico node install-cni container is not coming up
Pod can’t ping other worker node
Now, i sucessfully created a cluster include 1 master, 3 worker node. All cluster be communicated by Calico CNI
