# 方法1 使用base64用户名密码
apiVersion: v1
kind: Secret

  namespace: default
type: kubernetes.io/basic-auth
data:
  username: dXNlcg== # 用户名base64格式: user
  password: cGFzc3dvcmQ= # 密码: password
---

# 定义中间件
apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
  name: test-auth
spec:
  basicAuth:
    secret: authsecret2

引用方法 IngressRoute

apiVersion: traefik.io/v1alpha1
kind: IngressRoute
metadata:
  name: xxx
spec:
  entryPoints:
    - websecure
  routes:
  - match: Host(`dash.xx.com`)
    kind: Rule
    middlewares:
    - name: test-auth
      namespace: default
    ...
