IstioService MeshmTLSTraffic Management 5 min read
Istio architecture, traffic management, mTLS and observability.
Architecture¶
istioctl install --set profile=default
kubectl label namespace default istio-injection=enabled
Data plane (Envoy sidecars) + Control plane (istiod).
Traffic Management¶
apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
name: my-api
spec:
hosts: [my-api]
http:
- route:
- destination: {host: my-api, subset: v1}
weight: 90
- destination: {host: my-api, subset: v2}
weight: 10
mTLS¶
apiVersion: security.istio.io/v1beta1
kind: PeerAuthentication
metadata:
name: default
namespace: istio-system
spec:
mtls:
mode: STRICT
Automatic encryption between all services, zero-code.
Summary¶
Istio = the most comprehensive mesh. mTLS + traffic management + observability without code changes.
