found an e2e bug in https://internal.pingcap.net/idc-jenkins/blue/organizations/jenkins/operator_ghpr_e2e_test_kind/detail/operator_ghpr_e2e_test_kind/588/pipeline/
it's possible that a TiKV pod has hostNetwork set to true but dnsPolicy is ClusterFirst
, e.g.
apiVersion: v1
kind: Pod

I guess the root cause is https://github.com/kubernetes/kubernetes/issues/78420 and fixed by https://github.com/kubernetes/kubernetes/pull/78853.
this bug has been fixed in Kubernetes 1.13+
right now, we should disable the host network test in 1.12.x cluster
we can add some unit tests to verify that hostNetwork fields can be set correctly
