NetworkPolicy causes pods to enter CrashLoopBackOff or Failed states
Issue
- I have implemented what I believe to be the correct policy configuration for NetworkPolicy which is blocking horizontal traffic and allowing egress traffic
- However, it is not allowing traffic in via the ingress routers. This is also causing healthchecks to fail intermittently and the pods to crash.
- After setting up a Deny-All NetworkPolicy, pods keep crashing
apiVersion: extensions/v1beta1
