kubernetes-1.12.1安装dashboardv1.10.1

1.因为中国墙的问题，所以首先要准备好镜像，请使用如下脚本下载

因为你不知道pod会被调度到那个NODE上，所以你要在每个NODE上都得执行一下脚本

#!/bin/sh#拉取镜像docker pull registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0#重新打标签docker tag registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0 k8s.gcr.io/kubernetes-dashboard-amd64:v1.10.0#删除无用镜像docker image rm registry.cn-qingdao.aliyuncs.com/wangxiaoke/kubernetes-dashboard-amd64:v1.10.0

2.开始安装

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

• 查看dashboard的POD是否正常启动，如果正常说明安装成功

  [root@node1 ~]# kubectl get pods --namespace=kube-systemNAME ????????????????????????????????????READY ??STATUS ???RESTARTS ??AGEcoredns-576cbf47c7-kg8s9 ????????????????1/1 ????Running ??0 ?????????29hcoredns-576cbf47c7-st599 ????????????????1/1 ????Running ??0 ?????????29hetcd-node1.ztpt.com ?????????????????????1/1 ????Running ??0 ?????????29hkube-apiserver-node1.ztpt.com ???????????1/1 ????Running ??0 ?????????29hkube-controller-manager-node1.ztpt.com ??1/1 ????Running ??1 ?????????29hkube-flannel-ds-amd64-79x9h ?????????????1/1 ????Running ??0 ?????????27hkube-flannel-ds-amd64-f9fls ?????????????1/1 ????Running ??0 ?????????26hkube-flannel-ds-amd64-q7kvx ?????????????1/1 ????Running ??0 ?????????29hkube-proxy-242zg ????????????????????????1/1 ????Running ??0 ?????????27hkube-proxy-5ntm5 ????????????????????????1/1 ????Running ??0 ?????????29hkube-proxy-6pbrv ????????????????????????1/1 ????Running ??0 ?????????26hkube-scheduler-node1.ztpt.com ???????????1/1 ????Running ??1 ?????????29hkubernetes-dashboard-77fd78f978-wzqjq ???1/1 ????Running ??0 ?????????5m7s

3.配置外网访问（不配置的话默认只能集群内访问）

• 修改service配置，将type: ClusterIP改成NodePort

  kubectl edit service ?kubernetes-dashboard --namespace=kube-system

• 查看外网暴露端口(我们可以看到外网端口是32240)

  [root@node1 ~]# kubectl get service --namespace=kube-systemNAME ??????????????????TYPE ???????CLUSTER-IP ??????EXTERNAL-IP ??PORT(S) ????????AGEkube-dns ??????????????ClusterIP ??10.96.0.10 ??????<none> ???????53/UDP,53/TCP ??47hkubernetes-dashboard ??NodePort ???10.101.221.220 ??<none> ???????443:32240/TCP ??17h

4.访问dashboard

• 创建dashboard用户
  1.创建admin-token.yaml文件，文件内容如下：

kind: ClusterRoleBindingapiVersion: rbac.authorization.k8s.io/v1beta1metadata: ?name: admin ?annotations: ???rbac.authorization.kubernetes.io/autoupdate: "true"roleRef: ?kind: ClusterRole ?name: cluster-admin ?apiGroup: rbac.authorization.k8s.iosubjects:- kind: ServiceAccount ?name: admin ?namespace: kube-system---apiVersion: v1kind: ServiceAccountmetadata: ?name: admin ?namespace: kube-system ?labels: ???kubernetes.io/cluster-service: "true" ???addonmanager.kubernetes.io/mode: Reconcile

2.创建用户

[root@node1 ~]# kubectl create -f admin-token.yaml 

• 获取登陆token

  [root@node1 ~]# kubectl describe secret/$(kubectl get secret -nkube-system |grep admin|awk ‘{print $1}‘) -nkube-system

• 通过浏览器登陆dashboard（我用的火狐浏览器）

  注意，因为证书的问题，浏览器可能会阻止连接，必须把访问地址加入到访问例外里面

1.打开浏览器输入访问地址

访问地址：https://192.168.2.170:32240 ??格式：https://节点IP:bashboard暴露端口

2.认证方式选择口令，输入刚才获取到的token，即可登陆成功。

3.进入后就会看到如下界面
