Service Mesh with Istio: Secure Microservice Communication
Deploy Istio for traffic management and mTLS—but misconfiguration causes cascading failures
Service Mesh with Istio: Secure Microservice Communication
Istio provides traffic management, security, and observability for microservices. This guide covers production deployment patterns.
Istio Installation
Deploy Istio control plane:
```bash
Install Istio
istioctl install --set profile=production
Enable sidecar injection for namespace
kubectl label namespace default istio-injection=enabled
Verify installation
kubectl get pods -n istio-system ```
Mutual TLS Configuration
Enforce encrypted communication:
```yaml
peer-authentication.yaml - Enforce mTLS
apiVersion: security.istio.io/v1beta1 kind: PeerAuthentication metadata: name: default namespace: istio-system spec: mtls: mode: STRICT # Require mTLS for all traffic
