kubernetes-dashboard 部署

Kubernetes Dashboard 是 Kubernetes 官方提供的一个 Web 界面，用于管理 Kubernetes 集群。以下是部署 Kubernetes Dashboard 的步骤:

1. 下载 Kubernetes Dashboard YAML 文件:

curl -LO https://raw.githubusercontent.com/kubernetes/dashboard/v2.4.0/aio/deploy/recommended.yaml

2. 修改 Kubernetes Dashboard Service 类型:

将 recommended.yaml 文件中的 Service 类型从 ClusterIP 修改为 NodePort，这样可以通过 Node 的 IP 地址加端口号访问 Kubernetes Dashboard。

apiVersion: v1
kind: Service
metadata:
  name: kubernetes-dashboard
  namespace: kubernetes-dashboard
  labels:
    k8s-app: kubernetes-dashboard
spec:
  type: NodePort # 将类型修改为 NodePort
  ports:
    - port: 443
      targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard

3. 部署 Kubernetes Dashboard:

kubectl apply -f recommended.yaml

4. 创建 Service Account:

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kubernetes-dashboard
EOF

5. 创建 Cluster Role Binding:

cat <<EOF | kubectl apply -f -
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: admin-user
  namespace: kubernetes-dashboard
EOF

6. 获取 Token:

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

7. 访问 Kubernetes Dashboard:

使用浏览器访问 Node 的 IP 地址加端口号，输入 Token 登录即可。
