SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams secure internal service traffic with mutual TLS so every service proves its identity before exchanging data.

Core Features & Use Cases

  • Zero-trust service-to-service communication policies for Kubernetes and service meshes.
  • Certificate hierarchy guidance for root, intermediate, and workload identities.
  • Practical setup patterns for Istio, cert-manager, SPIFFE/SPIRE, and Linkerd.
  • Troubleshooting support for TLS handshake failures and certificate rotation.
  • Use it when hardening internal APIs, meeting compliance requirements, or rolling out mTLS gradually across mixed workloads.

Quick Start

Ask the skill to design a secure mTLS rollout for your cluster, including policy mode, certificate flow, and debugging checks.

FAQPage Schema
How do I set up mutual TLS for zero-trust service-to-service communication in Kubernetes?▼

Mutual TLS in Kubernetes requires configuring strict or permissive policies, destination rules, and certificate issuance to ensure every service proves its identity before exchanging data across the mesh.

Can I use cert-manager and SPIFFE for workload identity integration during mTLS rollout?▼

Yes, mTLS configuration supports cert-manager and SPIFFE/SPIRE for workload identity integration, providing certificate hierarchy guidance for root, intermediate, and workload identities across your services.

What is the best way to gradually roll out mTLS across mixed workloads in Istio?▼

The best approach for rolling out mTLS in Istio involves starting with permissive policy mode, configuring destination rules, and progressively enforcing strict mutual TLS to harden internal APIs without disrupting existing traffic.

Why does my TLS handshake fail during certificate rotation in a service mesh?▼

TLS handshake failures during certificate rotation often stem from misconfigured workload identities, expired intermediate certificates, or incomplete destination rules that prevent services from validating peer identities.

How does mTLS policy mode affect service traffic in Linkerd?▼

mTLS policy mode in Linkerd determines whether services enforce strict identity verification or allow permissive plaintext traffic, directly impacting zero-trust networking compliance and internal API security.
