安装Dashboard

首先先下载官方的yaml文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta5/aio/deploy/recommended.yaml

访问方式

1、直接https

修改访问方式，这个地方可以随机分配也可以直接指定，在这里我指定了端口

kind: Service
apiVersion: v1
metadata:
 labels:
 k8s-app: kubernetes-dashboard
 name: kubernetes-dashboard
 namespace: kubernetes-dashboard
spec:
 type: NodePort
 ports:
 - port: 443
 targetPort: 8443
 nodePort: 30018 #指定端口为30018，不写则为随机分配
 selector:
 k8s-app: kubernetes-dashboard

2、kubectl proxy 方式访问

开启kubectl proxy

 kubectl proxy --address='0.0.0.0' --accept-hosts='^*$'

访问地址

http://192.168.136.134:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

这里的地址是master节点的地址

开始安装

kubectl create -f ~/recommended.yaml

检查pad是否启动

kubectl get pods -A -o wide

kubectl get service -n kubernetes-dashboard -o wide

创建账号

创建admin账号

cat < dashboard-admin.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
 labels:
 k8s-app: kubernetes-dashboard
 name: dashboard-admin
 namespace: kubernetes-dashboard
EOF

kubectl create -f dashboard-admin.yaml

为用户分配权限

cat < dashboard-admin-bind-cluster.yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
 name: dashboard-admin-bind-cluster-role
 labels:
 k8s-app: kubernetes-dashboard
roleRef:
 apiGroup: rbac.authorization.k8s.io
 kind: ClusterRole
 name: cluster-admin
subjects:
- kind: ServiceAccount
 name: dashboard-admin
 namespace: kubernetes-dashboard
EOF

kubectl create -f dashboard-admin-bind-cluster.yaml

查看token

kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep dashboard-admin | awk '{print $1}')
 

选择第二个输入图中的token

因为我们没有安装metrics-server所以Pods的CPU、内存情况是看不到的，下面我们安装一下。

安装metrics-server

下载镜像包

docker pull bluersw/metrics-server-amd64:v0.3.6
docker tag bluersw/metrics-server-amd64:v0.3.6 k8s.gcr.io/metrics-server-amd64:v0.3.6 

执行下面的命令

mkdir metrics-server

cd metrics-server 


wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/aggregated-metrics-reader.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/auth-delegator.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/auth-reader.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/metrics-apiservice.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/metrics-server-deployment.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/metrics-server-service.yaml

wget https://raw.githubusercontent.com/kubernetes-incubator/metrics-server/master/deploy/1.8%2B/resource-reader.yaml

修改配置文件

安装metrics-server

kubectl apply -f ./

访问一下就可以看到资源了
