Are there any resources for using Kubernetes Network Policies with Istio? What access should I give istio to my namespaces and vice versa to allow for configuration?
K8s Network policies is on a different level of access control and is enforced out of Istio. I think you just need to allow access from the istio-system namespace in your k8s network policy so that Istio control plane is able to talk to the Envoy in your pods.
