1. Deploying the Dashboard UI

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.1.0/aio/deploy/recommended.yaml

如果执行报错，请先将该文件下载到本地，然后再 kubectl apply Unable to connect to the server: tls: first record does not look like a TLS handshake

2. Creating sample user

接着创建访问 K8S Dashboard UI 的账号

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: ServiceAccount

  name: admin-user
  namespace: kubernetes-dashboard
EOF

2.2 Creating a ClusterRoleBinding

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: admin-user
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin

2.3 获取访问Token

kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"

3. Bind Port and Accessing the Dashboard UI

Bind Port

kubectl proxy

使用 上一步创建的 token，访问 K8S Dashboard UI
