Manage network policies and Kafka ACLs in a Kubernetes cluster with ease.
However, if you want to control pod-to-pod communication, you might be better suited with managing network policies using ClientIntents, which let you specify which pods should communicate with which, from the client's point of view, and without requiring labels beforehand. It's open source, have a look at the intents operator here: https://github.com/otterize/intents-operator
Kubernetes Native Policy Management
You do still have to create a policy for every namespace, but don't have to worry about labeling individual pods. We're starting to move to Helm/kustomize for our namespaces to deploy default things like network policies to each one, and we're also starting to use kyverno more, which I think is a little more purpose built for this type of thing than metacontroller is.
