Kubernetes 入口域重定向

Question

我想在 nginx 入口 kubernete 中重定向域。

https://test.example.io/preview/qLxiVcDGxCaQ134650121853FTg4

如果在 url preview中來更改域重定向

https://test.app.example.io/preview/qLxiVcDGxCaQ134650121853FTg4

我在嘗試什么

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    certmanager.k8s.io/cluster-issuer: staging
    nginx.ingress.kubernetes.io/rewrite-target: /
    kubernetes.io/ingress.class: nginx
  name: staging-ingress
spec:
  rules:
  - host: test.example.io
    http:
      paths:
      - path: /
        backend:
          serviceName: service-1
          servicePort: 80
      - path: /preview/*
        backend:
          url: 
          serviceName: service-2
          servicePort: 80
  tls:
  - hosts:
    - test.example.io
    secretName: staging

對於簡單的 nginx 塊就像

location ~ /preview
    {
      rewrite /preview https://test.app.example.com$uri permanent;
    }

Answer 1

我的邏輯思維，試試看：

metadata:
      annotations:
        nginx.ingress.kubernetes.io/configuration-snippet: |
         rewrite /preview https://test.app.example.com$uri permanent;

spec:
      rules:
      - host: test.example.io
        http:
          paths:
          - path: /
            backend:
              serviceName: service-1
              servicePort: 80
      - host: test.app.example.io
        http:
          paths:
          - path: /preview/*
            backend:
              serviceName: service-2
              servicePort: 80

希望它有效！

在上面的代碼上：您根本不應該使用： https://test.app.example.io/preview/ （它只是被重定向鏈接）訪問。

使用 nginx 入口注釋

nginx.ingress.kubernetes.io/server-snippet: |
      location ~ /preview {
         rewrite /preview https://test.app.example.com$uri permanent;
      }

嘗試這個 -

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    certmanager.k8s.io/cluster-issuer: staging
    nginx.ingress.kubernetes.io/rewrite-target: /$1
    kubernetes.io/ingress.class: nginx
  name: staging-ingress
spec:
  rules:
  - host: test.example.io
    http:
      paths:
      - path: /(.*)
        backend:
          serviceName: service-1
          servicePort: 80
      - path: /preview/(.*)
        backend: 
          serviceName: service-2
          servicePort: 80
  tls:
  - hosts:
    - test.example.io
secretName: staging
