How does this skill improve Kubernetes security?

It helps implement the principle of least privilege by generating precise network policies that restrict traffic only to authorized pod communications, reducing the blast radius of potential breaches.

Does it support specific ports and labels?

Absolutely. You can specify complex pod selectors, namespaces, and specific port ranges to create highly granular ingress and egress rules.

Can I use this for existing Kubernetes clusters?

Yes, the skill can analyze and modify existing network policies to refine your security posture or update rules to match evolving application requirements.

Is this skill compatible with CI/CD pipelines?

Yes, it generates standard Kubernetes YAML files that can be integrated into your GitOps workflow and applied via tools like kubectl, ArgoCD, or Flux.
