Kubernetes 入口路徑

Question

我使用 yaml 文件為前端和后端設置了 nginx-ingress。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: polls-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    nginx.ingress.kubernetes.io/service-upstream: "true"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
spec:
  tls:
  - hosts:
    - example.com
    secretName: polls-tls
  rules:
  - host: example.com
    http:
      paths:
      - path: /(.*)
        backend:
          serviceName: frontend
          servicePort: 3000
      - path: /graphql/(.*)
        backend:
          serviceName: polls
          servicePort: 8000

目前，我的重寫目標重新路由如下

example.com  => / of frontend app
example.com/ => / of frontend app
example.com/graphql => / of frontend app
example.com/graphql/post => / of frontend app

example.com/graphql/ => / of backend app
example.com/graphql/post/ => /post of backend app

但我希望后端應用程序同時用於 graphql/post 和 graphql/post/ ，如下所示。

example.com => / of frontend app
example.com/ => / of frontend app
example.com/hello => /hello of frontend app
example.com/test => /test of frontend app

example.com/graphql => / of backend app
example.com/graphql/ => / of backend app
example.com/grpahql/post => /post of backend app
example.com/graphql/post/ => /post of backend app

誰能告訴我如何實現它？

您需要更改 graphql 路徑的正則表達式，如下所示：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: polls-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    nginx.ingress.kubernetes.io/service-upstream: "true"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
spec:
  tls:
  - hosts:
    - example.com
    secretName: polls-tls
  rules:
  - host: example.com
    http:
      paths:
      - path: /(.*)
        backend:
          serviceName: frontend
          servicePort: 3000
      - path: /graphql/?(.*)   # <- HERE add "?"
        backend:
          serviceName: polls
          servicePort: 8000

來自正則表達式的文檔：

問號表示前面的元素出現零次或一次。 例如，colou?r 匹配“顏色”和“顏色”。

我無法發表評論，所以我沒有在這里發表回應，你有沒有設法解決這個問題？ 我面臨着同樣的事情。
