Configure mTLS for Service Meshes

Teams need consistent mTLS configuration across service meshes and certificate tooling. This skill provides practical templates, checks, and troubleshooting steps for secure service-to-service communication.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request

Review the Skillstore skill "mtls-configuration" from https://skillstore.io/skills/wshobson-mtls-configuration.md and its manifest at https://skillstore.io/api/skills/wshobson-mtls-configuration/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "mtls-configuration". Request: Enable strict mTLS for a namespace.

Expected outcome:

A staged migration checklist with permissive mode, policy review, strict enforcement, and validation steps.

Using "mtls-configuration". Request: Debug a failed handshake between two services.

Expected outcome:

A diagnostic sequence covering service identity, destination policy, certificate status, proxy logs, and namespace scope.

Using "mtls-configuration". Request: Plan certificate rotation for workloads.

Expected outcome:

A rotation plan with short certificate lifetimes, renewal windows, monitoring signals, and rollback considerations.

Security Audit

Safe

v7 • 7/8/2026 Open versioned report

Static alerts were caused by Markdown code fences, service mesh configuration examples, resource links, and placeholder certificate paths in SKILL.md. I found no prompt injection, secret exfiltration intent, or hidden executable code. The skill is security-focused documentation, but users should review cluster commands before applying them.

What You Can Build

Migrate a Namespace to Strict mTLS

Plan a safe move from permissive mode to strict service-to-service authentication.

Design Certificate Rotation

Create a short-lived certificate workflow with cert-manager and operational checks.

Debug Mesh Handshake Failures

Use mesh status, identity, and log checks to isolate mTLS failures.

Try These Prompts

Enable Namespace mTLS

Explain how to enable strict mTLS for one Kubernetes namespace using Istio. Include the migration order and checks before enforcement.

Plan a Service Migration

Create an Istio mTLS plan for a payments service that currently talks to legacy services. Include permissive migration, DestinationRules, and validation checks.

Build Certificate Rotation

Design a certificate rotation workflow for Istio workloads using cert-manager. Include renewal timing, monitoring signals, and rollback steps.

Compare Mesh Identity Models

Compare Istio, Linkerd, and SPIFFE/SPIRE for multi-cluster zero-trust communication. Recommend one approach for regulated workloads and explain tradeoffs.

Best Practices

Start migrations in permissive mode, then enforce strict mTLS after validation.
Use short-lived workload certificates and monitor expiry before outages occur.
Keep trust domains, namespaces, and service identities explicit in every template.

Avoid

Disabling mTLS on production ports to bypass a failing deployment.
Embedding real private keys or CA material in shared configuration examples.
Applying mesh-wide strict policies before legacy service dependencies are mapped.

Frequently Asked Questions

Does this skill generate production certificates?

No. It provides configuration patterns and guidance. Use approved tooling to generate and store certificates.

Which service meshes are covered?

The skill covers Istio, Linkerd, SPIFFE/SPIRE, and cert-manager examples for Kubernetes environments.

Can I use it with Claude, Codex, and Claude Code?

Yes. The marketplace metadata marks the skill as compatible with Claude, Codex, and Claude Code.

Does it handle real private keys?

No. The examples use placeholders and file paths. Do not paste real private keys into prompts or shared files.

Is it limited to Kubernetes?

Most examples assume Kubernetes and a service mesh. The principles can inform other mTLS deployments.

Should commands be run automatically?

No. Review the current cluster context, namespace, and permissions before running any operational command.
