Kubernetes Dashboard可视化插件和Heapster监控组件部署（二）

[root@DEV004021 ~]# wget http://mirror.faasx.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

2、修改yaml文件中的镜像

3、修改yaml文件中的Dashboard Service，使其对外能够访问

4、启动Dashboard，并查看相关服务

[root@DEV004021 opt]# kubectl apply -f kubernetes-dashboard.yaml 
secret/kubernetes-dashboard-certs unchanged
clusterrolebinding.rbac.authorization.k8s.io/admin-user unchanged
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal unchanged
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal unchanged
deployment.apps/kubernetes-dashboard unchanged
service/kubernetes-dashboard unchanged
[root@DEV004021 opt]# kubectl --namespace=kube-system get deployment kubernetes-dashboard
NAME                   READY   UP-TO-DATE   AVAILABLE   AGE
kubernetes-dashboard   1/1     1            1           3d19h
[root@DEV004021 opt]# kubectl --namespace=kube-system get service kubernetes-dashboard
NAME                   TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)         AGE
kubernetes-dashboard   NodePort   10.1.104.20   <none>        443:31111/TCP   3d19h

5、访问Dashboard。地址是必须添加https

6、创建访问用户

---
# ------------------- Dashboard Service Account ------------------- #

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kube-system
---

7、获取登陆dsahboard的令牌，登陆面板如下：

[root@DEV004021 opt]# kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin-user | awk ‘{print $1}‘)

（二）、监控组件Heapster部署。
Heapster 用于计算并分析集群资源利用率、监控集群容器。
1、下载Heapster组件部署的yaml文件

# 新建文件夹，用于存放 Heapster 部署所需的 yaml 文件
mkdir heapster
cd heapster

# 获取相关 yaml 文件
wget https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/grafana.yaml
wget https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/heapster.yaml
wget https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/influxdb/influxdb.yaml
wget https://raw.githubusercontent.com/kubernetes/heapster/master/deploy/kube-config/rbac/heapster-rbac.yaml

2、修改yaml中的image值，把k8s.gcr.io 全部修改为 registry.cn-hangzhou.aliyuncs.com/google_containers

3、部署Heapster

[root@DEV004021 heapster]# kubectl create -f /opt/heapster/
deployment.extensions/monitoring-grafana created
service/monitoring-grafana created
clusterrolebinding.rbac.authorization.k8s.io/heapster created
serviceaccount/heapster created
deployment.extensions/heapster created
service/heapster created
deployment.extensions/monitoring-influxdb created
service/monitoring-influxdb created

4、查看效果
