kubernetes-1.12.1安装dashboardv1.10.1

安装kubernetes1.12.1的web-ui附件：dashboard:v1.10.0

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-system
  NAME                                     READY   STATUS    RESTARTS   AGE

  coredns-576cbf47c7-st599                 1/1     Running   0          29h

  kubernetes-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-system
  NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)         AGE
  kube-dns               ClusterIP   10.96.0.10               53/UDP,53/TCP   47h
  kubernetes-dashboard   NodePort    10.101.221.220           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: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: admin
  annotations:
    rbac.authorization.kubernetes.io/autoupdate: "true"
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
subjects:
- kind: ServiceAccount
  name: admin
  namespace: kube-system
---
apiVersion: v1
kind: ServiceAccount
metadata:
  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
