kubernetes1.5.2 部署dashboard服务

本文基于kubernetes 1.5.2版本编写

dashboard是一个可视化的web界面，可以简单管理k8s。

基于http方式访问的 dashboard 部署方式：

cat << EOF > dashboard-controller.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"

service ：

cat << EFO > dashboard-service.yaml 
apiVersion: v1
kind: Service
metadata:
  name: kubernetes-dashboard
  namespace: kube-system
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
spec:
  selector:
    k8s-app: kubernetes-dashboard
  ports:
  - port: 80
    targetPort: 9090
EOF

kubectl create -f dashboard-controller.yaml

kubectl create -f dashboard-service.yaml

 

访问方式：

http： http://192.168.85.6:8080/ui
https：https://192.168.85.6:6443/ui

如果API Server配置文件中没有配置登陆账号和密码（--basic-auth-file=/etc/kubernetes/useraccount.csv），登陆失败； 如果配置了，账号和密码为/etc/kubernetes/useraccount.csv任意中的一个

 

特别注意：

　　如果访问不通，请查看node节点的iptables FORWARD链，修改为ACCEPT
