注1:这里我用的镜像是自己搭建的镜像仓库来pull，写这篇博文时kube-dns更新到了1.14.6，开会，墙又高了许多，所以拉取困难，我用回了1.14.5的版本，这里自行更改，自己能科学上网拉取最新版当然更好。
注2:看对比，第二个不同，1.14.6版--probe最后是SRV，而1.14.5版最后是A，这儿也要更改，不然会产生 CrashLoopBackOff 错误。
注3:这里我们要使用--kube-master-url命令指定apiserver，不然也会产生 CrashLoopBackOff 错误。
注4: 我将镜像放在了网易蜂巢上，地址:

###替换所有 images
1
# sed -i 's/gcr.io\/google_containers/192.168.100.100\/k8s/g' *.yaml
注:这里我也将镜像放在了网易蜂巢上，请自行更改:
hub.c.163.com/zhijiansd/heapster-grafana-amd64:v4.4.3
hub.c.163.com/zhijiansd/heapster-amd64:v1.4.0
hub.c.163.com/zhijiansd/heapster-influxdb-amd64:v1.3.3
###更改 heapster.yaml

# grep source heapster.yaml
# - --source=kubernetes:https://kubernetes.default
- --source=kubernetes:http://192.168.100.104:8080?inClusterConfig=false
注: heapster 默认使用 https 连接 apiserver ，这里更改为使用 http 连接。

12. 部署 Kubernetes Dashboard
这里我们使用不需要证书的版本：
1
# curl -O https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/alternative/kubernetes-dashboard.yaml
### 替换 images
1
# sed -i 's/gcr.io\/google_containers/192.168.100.100\/k8s/g' kubernetes-dashboard.yaml
注:请自行更改镜像地址:
hub.c.163.com/zhijiansd/kubernetes-dashboard-amd64:v1.7.1
###添加 apiserver 地址
1

# grep apiserver kubernetes-dashboard.yaml
# - --apiserver-host=http://my-address:port
- --apiserver-host=http://192.168.100.104:8080
###执行该文件

# kubectl create -f kubernetes-dashboard.yaml
serviceaccount "kubernetes-dashboard" configured
role "kubernetes-dashboard-minimal" configured
rolebinding "kubernetes-dashboard-minimal" configured
deployment "kubernetes-dashboard" configured
service "kubernetes-dashboard" configured
###检查 kubernetes-dashboard 服务

# kubectl get pods -n kube-system | grep dash
kubernetes-dashboard-7648996855-54x6l 1/1 Running 1 7h
注:1.7版不能使用 kubectl cluster-info 查看到 kubernetes-dashboard 地址，1.6.3版的可以。
1.7.0版需要使用http://localhost:8080/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ 进行访问。而1.7.1版可以使用http://localhost:8080/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/ 访问，也可以使用http://localhost:8080/ui访问，其会自动跳转。
13.查看 kubernetes dashboard
使用http://localhost:8080/ui访问
节点界面
查看Pod界面
14. 查看 grafana
使用http://localhost:8080/api/v1/namespaces/kube-system/services/monitoring-grafana/proxy访问
查看Cluster
查看Pod
