# Linkerd Patterns

> Implement Linkerd service mesh patterns for lightweight, security-focused service mesh…

Production-ready patterns for the Linkerd service mesh, the lightweight, security-first mesh for Kubernetes. It covers automatic mTLS, traffic splitting for canary releases, per-route service profiles, retry budgets, and multi-cluster setups, all with copy-ready manifests.

## Use cases
- Setting up a lightweight service mesh with minimal overhead
- Enabling zero-config automatic mTLS between services
- Running canary deployments with traffic splits
- Configuring per-route metrics, retries, and timeouts
- Enforcing zero-trust access with authorization policies
- Linking and observing multi-cluster service meshes

## Benefits
- Encrypt all service-to-service traffic without touching app code
- Prevent cascading failures with retry budgets that stop retry storms
- Roll out new versions safely with weighted canary traffic
- See live golden signals: success rate, latency, and throughput

## What’s included
- Mesh installation and validation command sequence
- Namespace and deployment auto-injection templates
- ServiceProfile templates with retry budgets and per-route timeouts
- TrafficSplit, Server, and ServerAuthorization policy manifests
- HTTPRoute advanced routing and multi-cluster link setup
- Monitoring and debugging commands for tap, top, and identity

## Who it’s for
Platform and DevOps engineers running Kubernetes who want lightweight, secure service-mesh networking.

## How it runs
Zero trust with one annotation: meshed pods get automatic mTLS and 24-hour certificate rotation without touching application code. From staged install to golden-signal debugging, this is the Linkerd rollout in order.
1. Installs in verified stages: linkerd check --pre against the cluster, CRDs first, then the control plane, then linkerd check again; the viz extension comes last for dashboards and live traffic tooling.
2. Meshes workloads with one annotation: linkerd.io/inject enabled on the namespace or deployment, which buys automatic mTLS between all meshed pods with zero application code changes and 24-hour certificate rotation handled by the identity controller.
3. Writes ServiceProfiles per service to unlock route-level truth: per-route metrics, timeouts and retries, with isRetryable true only on idempotent GET routes and a retryBudget (20 percent ratio) so retries can never snowball into a retry storm.
4. Splits traffic for canaries with TrafficSplit: stable at 900m, canary at 100m, shifting weight as the golden metrics hold.
5. Locks down access with Server and ServerAuthorization: which ServiceAccounts may talk to which ports over mesh TLS, with a separate explicit CIDR-scoped allowance for unauthenticated ingress traffic.
6. Watches and debugs with the golden signals: linkerd viz top and routes for live success rate and p50/p95/p99 latency, viz edges to confirm mTLS between deployments, and viz tap to watch individual live requests when something looks off.

## FAQ
### We are already on Istio. Do these patterns transfer?
The concepts (mTLS, canary splits, retry policies) transfer, but the manifests do not: ServiceProfile, TrafficSplit, Server, and ServerAuthorization are Linkerd resources. This is for teams running or adopting Linkerd specifically, often because they want a lighter mesh than Istio.

### How does it encrypt service-to-service traffic without me touching application code?
Linkerd's auto-injection adds a sidecar proxy at the namespace or deployment level, and the proxies negotiate mutual TLS between themselves. The skill gives you the injection templates plus the validation command sequence to confirm encryption and workload identity are actually live.

### Does it cover VMs or services outside Kubernetes?
No. Everything here assumes Kubernetes: installation, auto-injection, traffic policies, and the multi-cluster linking patterns all operate on cluster resources. Off-cluster workloads are out of scope.
