Kubernetes 1.8.6 集群部署–部署Web UI界面（七）
安装DNS插件
在 Master节点 上进行安装操作
下载安装文件
# cd
# wget https://github.com/kubernetes/kubernetes/releases/download/v1.8.6/kubernetes.tar.gz
# tar xzvf kubernetes.tar.gz
# cd /root/kubernetes/cluster/addons/dns
# mv kubedns-svc.yaml.sed kubedns-svc.yaml
#把文件中$DNS_SERVER_IP替换成10.254.0.2
# sed -i 's/$DNS_SERVER_IP/10.254.0.2/g' ./kubedns-svc.yaml
# mv ./kubedns-controller.yaml.sed ./kubedns-controller.yaml
#把$DNS_DOMAIN替换成cluster.local
# sed -i 's/$DNS_DOMAIN/cluster.local/g' ./kubedns-controller.yaml
# ls *.yaml

deployment "kube-dns" created
serviceaccount "kube-dns" created
service "kube-dns" created部署 dashboard 插件
在master节点部署
新增部署配置文件
需要2个文件。
文件一

分别执行2个部署文件
kubectl create -f dashboard.yaml
kubectl create -f dashboard-svc.yaml如何访问？
[[email protected] dashboard]# kubectl get po -n kube-system -o wide

monitoring-influxdb-7c77768d9-9nbbv 1/1 Running 0 1h 172.30.61.5 192.168.161.162首先查看一下部署的服务是否正常？
如上可以很清晰的看到 咱们部署的 kubernetes-dashboard 在 192.168.161.163 上面已经部署了。
那我们可以去访问下：
http://192.168.161.163:8888部署 heapster 插件
下载安装文件
# wget https://github.com/kubernetes/heapster/archive/v1.5.0.tar.gz
# tar xzvf ./v1.5.0.tar.gz
# cd ./heapster-1.5.0/
[[email protected] heapster-1.5.0]# kubectl create -f deploy/kube-config/influxdb/
deployment "monitoring-grafana" created
service "monitoring-grafana" created
serviceaccount "heapster" created
deployment "heapster" created
service "heapster" created
deployment "monitoring-influxdb" created
service "monitoring-influxdb" created
[[email protected] heapster-1.5.0]# kubectl create -f deploy/kube-config/rbac/heapster-rbac.yaml
clusterrolebinding "heapster" created登录dashboard
当然最后真的很想说，结果我非常满意，中间入了很多坑，耗费了很长时间，但最终还是一个人搞定了。
重点留在后面，顺便给大家说下，架构所涉及的镜像源均为google的，你们也懂的，被墙的不行不行的！在此我把所有的镜像换成了阿里的如下：
大家对照着自行修改！！
文中用到的服务安装包 我已经下载好 放在了云盘：
