3.安装kubernetes-dashboard-2版本（kubernetes的web ui界面）
把kubernetes-dashboard镜像上传到各个节点，按照如下方法通过docker load -i解压，镜像地址在文章开头处的百度网盘里，可自行下载
docker load -i dashboard_2_0_0.tar.gz
docker load -i metrics-scrapter-1-0-1.tar.gz
解压出来的镜像是kubernetesui/dashboard:v2.0.0-beta8和kubernetesui/metrics-scraper:v1.0.1
在master1节点操作
kubectl apply -f kubernetes-dashboard.yaml
kubernetes-dashboard.yaml文件内容在如下链接地址处复制https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/kubernetes-dashboard.yaml
上面如果访问不了，可以访问下面的链接，然后把下面的分支克隆和下载，手动把yaml文件传到master1上即可：
https://github.com/luckylucky421/kubernetes1.17.3
查看dashboard是否安装成功：
kubectl get pods -n kubernetes-dashboard
显示如下，说明dashboard安装成功了
NAME READY STATUS RESTARTS AGE dashboard-metrics-scraper-694557449d-8xmtf 1/1 Running 0 60s kubernetes-dashboard-5f98bdb684-ph9wg 1/1 Running 2 60s
查看dashboard前端的service
kubectl get svc -n kubernetes-dashboard
显示如下：
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE dashboard-metrics-scraper ClusterIP 10.100.23.9 <none> 8000/TCP 50s kubernetes-dashboard ClusterIP 10.105.253.155 <none> 443/TCP 50s
修改service type类型变成NodePort：
kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
把type: ClusterIP变成 type: NodePort，保存退出即可。
kubectl get svc -n kubernetes-dashboard
显示如下：
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE dashboard-metrics-scraper ClusterIP 10.100.23.9 <none> 8000/TCP 3m59s kubernetes-dashboard NodePort 10.105.253.155 <none> 443:31175/TCP 4m
上面可看到service类型是NodePort，访问master1节点ip:31175端口即可访问kubernetes dashboard，我的环境需要输入如下地址
可看到出现了dashboard界面
3.1通过yaml文件里指定的默认的token登陆dashboard
1）查看kubernetes-dashboard名称空间下的secret
kubectl get secret -n kubernetes-dashboard
显示如下：
NAME TYPE DATA AGE default-token-vxd7t kubernetes.io/service-account-token 3 5m27s kubernetes-dashboard-certs Opaque 0 5m27s kubernetes-dashboard-csrf Opaque 1 5m27s kubernetes-dashboard-key-holder Opaque 2 5m27s kubernetes-dashboard-token-ngcmg kubernetes.io/service-account-token 3 5m27s
2）找到对应的带有token的kubernetes-dashboard-token-ngcmg
kubectl describe secret kubernetes-dashboard-token-ngcmg -n kubernetes-dashboard
显示如下：
...

点击sing in登陆，显示如下，这次就可以看到和操作任何名称空间的资源了
4.安装metrics组件
把metrics-server-amd64_0_3_1.tar.gz和addon.tar.gz镜像上传到各个节点，按照如下方法通过docker load -i解压，镜像地址在文章开头处的百度网盘里，可自行下载
docker load -i metrics-server-amd64_0_3_1.tar.gz
docker load -i addon.tar.gz
metrics-server版本0.3.1，用到的镜像是k8s.gcr.io/metrics-server-amd64:v0.3.1
addon-resizer版本是1.8.4，用到的镜像是k8s.gcr.io/addon-resizer:1.8.4
在k8s的master1节点操作
kubectl apply -f metrics.yaml
metrics.yaml文件内容在如下链接地址处复制
https://raw.githubusercontent.com/luckylucky421/kubernetes1.17.3/master/metrics.yaml
上面如果访问不了，可以访问下面的链接，然后把下面的分支克隆和下载，手动把yaml文件传到master1上即可：
https://github.com/luckylucky421/kubernetes1.17.3
上面组件都安装之后，查看组件安装是否正常，STATUS状态是Running，说明组件正常，如下所示：
kubectl get pods -n kube-system -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATE calico-node-h66ll 1/1 Running 0 51m 192.168.0.56 node1 <none> calico-node-r4k6w 1/1 Running 0 58m 192.168.0.6 master1 <none> coredns-66bff467f8-2cj5k 1/1 Running 0 70m 10.244.0.3 master1 <none> coredns-66bff467f8-nl9zt 1/1 Running 0 70m 10.244.0.2 master1 <none> etcd-master1 1/1 Running 0 70m 192.168.0.6 master1 <none> kube-apiserver-master1 1/1 Running 0 70m 192.168.0.6 master1 <none> kube-controller-manager-master1 1/1 Running 0 70m 192.168.0.6 master1 <none> kube-proxy-qts4n 1/1 Running 0 70m 192.168.0.6 master1 <none> kube-proxy-x647c 1/1 Running 0 51m 192.168.0.56 node1 <none> kube-scheduler-master1 1/1 Running 0 70m 192.168.0.6 master1 <none> metrics-server-8459f8db8c-gqsks 2/2 Running 0 16s 10.244.1.6 node1 <none> traefik-ingress-controller-xhcfb 1/1 Running 0 39m 192.168.0.6 master1 <none> traefik-ingress-controller-zkdpt 1/1 Running 0 39m 192.168.0.56 node1 <none>
上面如果看到metrics-server-8459f8db8c-gqsks是running状态，说明metrics-server组件部署成功了，接下来就可以在master1节点上使用kubectl top pods -n kube-system或者kubectl top nodes命令
