Nginx入口路由问题

Question

我有关于url路径的问题。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: backend
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /v1/$1
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
    nginx.ingress.kubernetes.io/use-regex: "true"
spec:
  tls:
  - hosts:
    - backend.example.com
    secretName: backend-example-com
  rules:
  - host: backend.example.com
    http:
      paths:
      - path: /v9/anonymous/set-data/?(.*)
        backend:
          serviceName: backend2
          servicePort: 80
      - path: /v9/?(.*)
        backend:
          serviceName: backend1
          servicePort: 80

在服役中我得到了

/v1/

但我应该得到

/v1/anonymous/set-data/foo/bar/

我需要重写/v1/路径中的所有版本，一些请求应该转到backend1，但一些特定路径应该转到backend2

找到解决方案

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: backend
  annotations:
#    nginx.ingress.kubernetes.io/rewrite-target: /v1/$1
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-redirect: "true"
    cert-manager.io/cluster-issuer: "letsencrypt-prod"
    nginx.ingress.kubernetes.io/use-regex: "true"
    nginx.ingress.kubernetes.io/configuration-snippet: |
      rewrite ^/v9/?(.*)$ /v1/$1 break;
spec:
  tls:
  - hosts:
    - backend.example.com
    secretName: backend-example-com
  rules:
  - host: backend.example.com
    http:
      paths:
      - path: /v9/anonymous/set-data/?(.*)
        backend:
          serviceName: backend2
          servicePort: 80
      - path: /v9/?(.*)
        backend:
          serviceName: backend1
          servicePort: 80

所有内容都重写为/v1/并正常工作
