Adding OVS bridges to Kubernetes worker-nodes break the Pod Network #3822

Open asoloa opened 4 years ago

asoloa commented 4 years ago

I was directed here by the Kubernetes support. See https://github.com/kubernetes/kubernetes/issues/92282

I have set up a multi-node Kubernetes cluster in CentOS. Currently using Weave Net for the pod network.

What happened?

Scenarios:

  1. Before adding OVS bridges to the worker nodes, the network works as expected (eg. pod can communicate with another pod in the other node).
  2. However after adding OVS bridges to the worker nodes (a simple ovs-vsctl add-br br1), the network breaks (eg. pod can't communicate with another pod in the other node, but pods within the same nodes can).:

What you expected to happen?

AFAIK, the networking between pods shouldn't be affected by the addition of the OVS bridges. Or am I understanding this wrong? Could this be a config-related issue? Additional procedures I may have missed?

Any help would be greatly appreciated. Thank you.

How to reproduce it?

  1. Installed containerd, docker, then kubeadm.
  2. kubeadm init
  3. Installed pod network (Weave Net)
  4. Created 2 sample pods (1 each node)
  5. Check pod connection via ping.
  6. Add OVS bridge in the nodes. (ovs-vsctl add-br br1)
  7. Check pod connection via ping. (No connection)
