四. 部署dashboard

# dashboard 2.x版本的部署
# 上传dashboard配置
$ scp target/addons/recommended.yaml <user>@<node-ip>:/etc/kubernetes/addons/
# 进行部署
$ kubectl apply -f /etc/kubernetes/addons/recommended.yaml
# 查看服务运行情况
$ kubectl get deployment kubernetes-dashboard -n kubernetes-dashboard
$ kubectl -n kubernetes-dashboard get pods -o wide
$ kubectl get services kubernetes-dashboard -n kubernetes-dashboard
$ netstat -ntlp|grep 30005

# 1. 下载配置文件
$ wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.1/aio/deploy/recommended.yaml

# 2. 修改配置文件（大约在32行Service段） 在spec 中加入 type: NodePort, nodePort: 30005 配置
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: 30005
  selector:
    k8s-app: kubernetes-dashboard

# 2. 进行部署
$ kubectl apply -f recommended.yaml

# 创建service account
$ kubectl create sa dashboard-admin -n kubernetes-dashboard

# 创建角色绑定关系
$ kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:dashboard-admin

# 查看dashboard-admin的secret名字
$ ADMIN_SECRET=$(kubectl get secrets -n kubernetes-dashboard | grep dashboard-admin | awk '{print $1}')

# 打印secret的token
$ kubectl describe secret -n kubernetes-dashboard ${ADMIN_SECRET} | grep -E '^token' | awk '{print $2}'
