Does it support cross-namespace traffic rules?

Yes, it can configure policies using namespaceSelectors to define communication boundaries between different logical environments in your cluster.

Can it help me implement a default-deny security posture?

Absolutely. The skill provides patterns for 'deny-all' ingress and egress policies to establish a secure baseline before adding explicit allow rules.

Does this skill support specific CNIs like Calico or Cilium?

Yes, it generates standard Kubernetes NetworkPolicy manifests which are compatible with any CNI plugin that supports the NetworkPolicy API, including Calico, Cilium, and Weave.

How does it handle DNS resolution issues?

The skill includes specific troubleshooting steps and rule templates to ensure pods can still reach kube-dns or coredns after restrictive egress policies are applied.

Automates the creation and management of Kubernetes NetworkPolicy manifests to enforce zero-trust security and least-privilege communication.

The Network Policy Manager skill streamlines the complex process of securing Kubernetes inter-pod communication. It helps developers and DevOps engineers generate precise YAML manifests for ingress and egress rules, ensuring that microservices only communicate with authorized peers. By leveraging pod and namespace selectors, the skill implements zero-trust architecture, helps troubleshoot connectivity issues, and provides templates for default-deny security postures across production environments.
