  ldez的答案是正确的，但有几点需要注意：

  • 首先，这些注释仅适用于traefik> = 1.6.x（早期版本可能支持错误页面，但不适用于kubernetes后端）

  • 其次，通过kubernetes配置traefik后端 must . 您无法在配置文件中创建后端并将其与kubernetes一起使用，至少在traefik 1.6.x中不能使用

  这是完整的事情的样子 . foo 只是一个名字，如另一个答案中所解释的那样，可以是任何名称：

  apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: frontend
    namespace: "default"
    annotations:
        external-dns.alpha.kubernetes.io/target: "domain.com"
        kubernetes.io/ingress.class: "traefik"
        traefik.ingress.kubernetes.io/error-pages: |-
          foo:
            status:
            - "404"
            - "500"
            # See below on where "error-pages" comes from
            backend: error-pages
            query: "/{{status}}.html"
  spec:
    rules:
     # This creates an ingress on an non-existing host name,
     # which binds to a service. As part of this a traefik
     # backend "error-pages" will be created, which is the one
     # we use above
     - host: error-pages
       http:
         paths:
         - backend:
           serviceName: error-pages-service
           servicePort: https
  - host: frontend.domain.com
      http:
      # The configuration for your "real" Ingress goes here
  
  # This is the service to back the ingress defined above
  # Note that you can use anything for this, including an internal app
  # Also: If you use https, the cert on the other side has to be valid
  ---
  kind: Service
  apiVersion: v1
  metadata:
    name: error-pages-service
    namespace: default
  spec:
    ports:
    - name: https
      port: 443
    type: ExternalName
    externalName: my-awesome-errors.mydomain.test
  

  如果您使用此配置，并且您的应用程序发送了404，那么 https://my-awesome-errors.mydomain.test/404.html 将显示为错误页面 .

  正确的语法是：

  apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: frontend
    namespace: "default"
    annotations:
        external-dns.alpha.kubernetes.io/target: "domain.com"
        kubernetes.io/ingress.class: "traefik"
        traefik.ingress.kubernetes.io/error-pages: |-
          foo:
            status:
            - "404"
            backend: bar
            query: /bar
          fii:
            status:
            - "500-600"
            backend: bar
            query: /bir
  spec:
    rules:
    - host: frontend.domain.com
      http:
        paths:
        - backend:
            serviceName: frontend
            servicePort: 3000
          path: /

  请注意，目前，Helm Charts不支持此功能 .

  Ingress不支持你们在那里使用的注释！仅使用Service支持注释，Ingress使用主机部分 .
