Mac搭建kubernetes dashboard全流程

1. 下载dashboard文件：

curl -o kubernetes-dashboard.yaml  https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

2. 修改文件：

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  # 添加Service的type为NodePort
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      # 添加映射到虚拟机的端口,k8s只支持30000以上的端口
      nodePort: 30001
  selector:
    k8s-app: kubernetes-dashboard

3. 创建kubernetes-dashboard：

kubectl create -f kubernetes-dashboard.yaml

4. 由于我之前安装过一次，所以报错：

Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": secrets "kubernetes-dashboard-certs" already exists
Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": serviceaccounts "kubernetes-dashboard" already exists
Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": roles.rbac.authorization.k8s.io "kubernetes-dashboard-minimal" already exists
Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": rolebindings.rbac.authorization.k8s.io "kubernetes-dashboard-minimal" already exists
Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": deployments.apps "kubernetes-dashboard" already exists
Error from server (AlreadyExists): error when creating "kubernetes-dashboard.yaml": services "kubernetes-dashboard" already exists

5. 卸载之前安装的内容：

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/aio/deploy/recommended/kubernetes-dashboard.yaml

6. 重新安装dashboard：

kubectl create -f kubernetes-dashboard.yaml

7. 获取token：

kubectl -n kube-system describe $(kubectl -n kube-system get secret -n kube-system -o name | grep namespace) | grep token

8. 启动kubernetes-dashboard：

kubectl proxy

9. 访问以下链接时，将获取的token粘贴到输入框中：

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/overview?namespace=default

 大功告成！ 

 如果登陆一会儿后发现提示token过期，强制退出，那么可以修改token的过期时间：

方式一：找到kubernetes-dashboard的配置文件，添加配置：

--token-ttl=43200

如下图所示：

2. 或者修改dashboard的yaml文件：

ports:
- containerPort: 8443
  protocol: TCP
args:
  - --auto-generate-certificates
  - --token-ttl=43200
