feat: allow dynamic list of ingress rules - #21
Merged
Conversation
The control NetworkPolicy only ever allowed traffic from the ingress-nginx namespace, with no way to add more. In clusters that deny pod-to-pod traffic by default, that leaves no way to permit other legitimate callers, such as PgDog pods reaching the control plane's API. Add networkPolicy.extraIngress, a list of NetworkPolicyIngressRule entries appended to the control NetworkPolicy's ingress rules verbatim, alongside the existing ingress-nginx rule.
