few days ago, i am facing a strange issue which is "a pod can not reach another pod running in the same minion/host through servide ClusterIP whereas they can reach each other skipping going through service clusterIP"
i am running kubernetes 1.9.6 on top of openstack (ubuntu 16.04 hosts) with:
- cni 0.7.0
- cri-containerd 1.0.0-beta
- flannel 0.9.1
- etcd 3.0.13
the other scenarios were working fine. even between pods running in different hosts, they can reach each other through service clusterIP.
what is going on here !!! any support will be more than welcome
