Hi!
Yes, but only one tiny:
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: allow-apiserver
namespace: calico-apiserver
ownerReferences:
- apiVersion: operator.tigera.io/v1
kind: APIServer
name: default
controller: true
blockOwnerDeletion: true
managedFields:
- manager: operator
operation: Update
apiVersion: networking.k8s.io/v1
spec:
podSelector:
matchLabels:
apiserver: 'true'
ingress:
- ports:
- protocol: TCP
port: 5443
policyTypes:
- Ingress
status: {}
But I guess it's an allow, not a block policy. (I'm somewhat new to
Kubernetes and not too familiar with network policies...)
Best regards,
Zsolt
