Centos8.0安装kubernetes-dashboard V2.0.0 Beta8

安完kubernetes了，为了方便就整一个dashboard，恰好看了看dashboard的2.0的bete8出来了，直接就开整，看看新UI到底咋样

先看看已有的环境（昨天搞的环境）

首先就要搞个证书，我就直接用我XX云的了，然后取名dashboard.crt和dashboard.key，放置到下面这个目录里面

# mkdir $HOME/certs

创建一个namespace

# kubectl create namespace kubernetes-dashboard

创建SSL证书的secret

# kubectl create secret generic kubernetes-dashboard-certs –from-file=$HOME/certs -n kubernetes-dashboard

下载Beta8的recommended.yaml

# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml

修改某些参数，为了部落

# vim recommended.yaml

spec:
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
改成
spec:
  type: NodePort   # 新增可以外网访问
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 30016     # 新增可以外网访问
  selector:
    k8s-app: kubernetes-dashboard 

将下面的全部注释
apiVersion: v1
kind: Secret
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard-certs
  namespace: kubernetes-dashboard
type: Opaque

- --auto-generate-certificates
- --namespace=kubernetes-dashboard
改成：
# - --auto-generate-certificates
- --tls-cert-file=/dashboard.crt
- --tls-key-file=/dashboard.key
- --token-ttl=3600
- --namespace=kubernetes-dashboard 

修改完成后就开始创建

# kubectl apply -f recommended.yaml

创建管理员权限

# vim admin.yaml

apiVersion: v1
 kind: ServiceAccount
 metadata:
   name: admin-user
   namespace: kubernetes-dashboard
 apiVersion: rbac.authorization.k8s.io/v1beta1
 kind: ClusterRoleBinding
 metadata:
   name: admin-user
   annotations:
     rbac.authorization.kubernetes.io/autoupdate: "true"
 roleRef:
   apiGroup: rbac.authorization.k8s.io
   kind: ClusterRole
   name: cluster-admin
 subjects:
 kind: ServiceAccount
 name: admin-user
 namespace: kubernetes-dashboard 

# kubectl apply -f admin.yaml

查一下token值

# kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk ‘{print $1}’)

打开IP:30016端口，输入刚才查出来的token，最炫暗黑模式搞起

搞定

卸载dashboard两个方法：

方法一：直接执行delete命令

# kubectl delete -f recommended.yaml

方法二：

# kubectl -n kubernetes-dashboard delete $(kubectl -n kubernetes-dashboard get pod -o name | grep dashboard)

注意： namespace 是自己设置的，有用kube-system的，我用的kubernetes-dashboard
