MetalLB 部署

安装 MetalLB

Istio 的 Ingress Gateway 需要使用 Loadbalancer 类型的 service 暴露，因此需要部署 MetalLB。此处使用二层模式即可。

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.12/config/manifests/metallb-native.yaml

kubectl -n metallb-system get po
NAME                          READY   STATUS    RESTARTS   AGE
controller-6c75847d5b-7jznb   1/1     Running   0          100s
speaker-7dpsv                 1/1     Running   0          100s
speaker-drg4m                 1/1     Running   0          100s
speaker-rxqjb                 1/1     Running   0          100s

创建 MetalLB IPPool（cluster1）：

cat > ippool1.yaml <<EOF

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: pool1
  namespace: metallb-system
spec:
  addresses:
  - 10.10.50.75-10.10.50.90
  autoAssign: true
---
apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: default
  namespace: metallb-system
spec:
  ipAddressPools:
  - pool1
EOF
kubectl apply -f ippool1.yaml

创建 MetalLB IPPool（cluster2）：

cat > ippool2.yaml <<EOF

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: pool2
  namespace: metallb-system
spec:
  addresses:
  - 10.29.8.75-10.29.8.90
  autoAssign: true
---
apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: default
  namespace: metallb-system
spec:
  ipAddressPools:
  - pool2
EOF
kubectl apply -f ippool2.yaml
