kubernetes - 为什么 Traefik v2 仅通过 http 响应 404

Question

我的问题是，我的 kubernetes 集群中的 traefik 入口 Controller 确实通过 http 响应 404 page not found，BUT 通过 https 我从服务中得到了真实的响应。

这是在我将 TLS 部分添加到 IngressRoute 后发生的。

这是我的 IngressRoute:

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: example-backend
  namespace: example
spec:
  entryPoints:
    - web
    - websecure
  routes:
  - match: Host(`api.example.com`)
    kind: Rule
    priority: 10
    services:
    - name: example-backend-service
      port: 80
  tls:
    secretName: tls-secret # I'm using my own certificate, not Let's Encrypt

为什么我没有得到像 https 那样的真实/相同的响应？

Answer 1

由于 TLS 适用于路由器，因此您不能只有一个 IngressRoute 来处理这 2 种情况。

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  name: example-backend
  namespace: example
spec:
  entryPoints:
    - websecure
  routes:
  - match: Host(`api.example.com`)
    kind: Rule
    priority: 10
    services:
    - name: example-backend-service
      port: 80
  tls:
    secretName: tls-secret
