通过operator部署istio

去看k8s配套的istio的版本

https://istio.io/latest/docs/releases/supported-releases/#support-status-of-istio-releases

 

1. 下载安装包

https://github.com/istio/istio/releases/download

2. 解压

tar xvf istio-1.17.2-linux-amd64.tar.gz

mv istio-1.17.2/bin/istioctl /usr/local/bin

验证：istioctl version

 

3. 安装isto的operator

 istioctl  operator init

执行完之后会多两个命名空间   istio-operator和istio-system（无内容）

# 安装
root@k8s-cluster:/data/istio-1.17.2# istioctl  operator  init
Installing operator controller in namespace: istio-operator using image: docker.io/istio/operator:1.17.2
Operator controller will watch namespaces: istio-system
✔ Istio operator installed                                                                 
✔ Installation complete

#查看
root@k8s-cluster:/data# kubectl get pod -n istio-operator
NAME                              READY   STATUS    RESTARTS   AGE
istio-operator-585ff76cb5-f8vxs   1/1     Running   0          35s

 

4. 安装istio

 istioctl manifest apply -f istio-operator.yaml 

安装完istio-system 会多两个pod，一个istiod，一个ingress-gateway

apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
metadata:
  namespace: istio-system
  name: example-istiocontrolplane
spec:
  profile: default
  components: # 自定义组件配置
    ingressGateways: # 自定义 ingressGateway 配置
      - name: istio-ingressgateway
        enabled: true # 开启 ingressGateway
        k8s:  # 自定义 ingressGateway 的 Kubernetes 配置
          service: # 将 Service 类型改成 NodePort
            type: NodePort
            ports:
            - port: 15020
              nodePort: 30520
              name: status-port
            - port: 80
              nodePort: 30080
              name: http2
              targetPort: 8080
            - port: 443
              nodePort: 30443
              name: https
              targetPort: 8443

 root@k8s-node:~# istioctl manifest apply -f istio-operator.yamlThis will install the Istio 1.18.2 default profile with ["Istio core" "Istiod" "Ingress gateways"] components into the cluster. Proceed? (y/N) y
