🐳 Azure Containers & AKS - Advanced

Service Mesh with Istio

# Install Istio
az aks mesh enable \
  --resource-group myResourceGroup \
  --name myAKSCluster

# Deploy virtual service
kubectl apply -f - <<EOF
apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: myservice
spec:
  hosts:
  - myservice
  http:
  - match:
    - uri:
        prefix: "/v2"
    route:
    - destination:
        host: myservice
        port:
          number: 80
EOF

Advanced Networking

# Create Azure CNI cluster
az aks create \
  --network-plugin azure \
  --network-policy azure \
  --service-cidr 10.0.0.0/16 \
  --dns-service-ip 10.0.0.10

Cluster Autoscaling

# Enable autoscaling
az aks nodepool update \
  --cluster-name myAKSCluster \
  --name nodepool1 \
  --resource-group myResourceGroup \
  --enable-cluster-autoscaler \
  --min-count 1 \
  --max-count 10
