這篇文章主要介紹了如何部署kubernetes-dashboard改成http免密登錄,本文給大家介紹的非常詳細,對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值,需要的朋友參考下吧

修改Service端口

增加80端口，改成http訪問

修改前:

spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard

修改后：

spec:
  ports:
    - port: 443
      targetPort: 8443
      name: https
    - port: 80
      targetPort: 9090
      name: http
  selector:
    k8s-app: kubernetes-dashboard

如果想用 ip+端口 的方式訪問，這里需要增加配置，改成 nodeport 的形式，nodePort 改成自己主機空閑的端口，取值范圍在 apiserver 的 --service-node-port-range 參數(shù)里面可以看得到

最終修改如下:

spec:
  ports:
    - port: 443
      targetPort: 8443
      name: https
      nodePort: 32001
    - port: 80
      targetPort: 9090
      name: http
      nodePort: 32002
  type: NodePort
  selector:
    k8s-app: kubernetes-dashboard

修改 deployment 內(nèi)容

修改探針檢測

后面要修改 dashboard 的啟動參數(shù)，這里不改的話，活性檢測會失敗，導(dǎo)致 pod 會不斷重啟

修改前:

          livenessProbe:
            httpGet:
              scheme: HTTPS
              path: /
              port: 8443

修改后:

          livenessProbe:
            httpGet:
              scheme: HTTP
              path: /
              port: 9090

修改鏡像拉取策略

官方 yaml 里面默認(rèn)配置的是 Always

sed -i 's/imagePullPolicy: Always/imagePullPolicy: IfNotPresent/g' recommended.yaml

修改容器端口

修改前:

          ports:
            - containerPort: 8443
              protocol: TCP

修改后:

          ports:
            - containerPort: 8443
              protocol: TCP
            - containerPort: 9090
              protocol: TCP

關(guān)閉 token 登錄

注釋掉 --auto-generate-certificates 參數(shù)

修改前:

          args:
            - --auto-generate-certificates
            - --namespace=kubernetes-dashboard
            # Uncomment the following line to manually specify Kubernetes API server Host
            # If not specified, Dashboard will attempt to auto discover the API server and connect
            # to it. Uncomment only if the default does not work.
            # - --apiserver-host=http://my-address:port

修改后:

          args:
            # - --auto-generate-certificates
            - --namespace=kubernetes-dashboard
            # Uncomment the following line to manually specify Kubernetes API server Host
            # If not specified, Dashboard will attempt to auto discover the API server and connect
            # to it. Uncomment only if the default does not work.
            # - --apiserver-host=http://my-address:port
