apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
# This NetworkPolicy is used to deny all ingress and egress traffic by default in this namespace,
# serving as a baseline. At the moment no other Network Policy should be needed:
# - CVO is a host-networked Pod, so it is not affected by network policies
# - Bare `version` Pods spawned by CVO do not require any network communication
name: default-deny
namespace: openshift-cluster-version
spec:
# Match all pods in the namespace
podSelector: {}
policyTypes:
- Ingress
- Egress
