Traefik Ingress 重写目标不执行任何操作

Question

我有一个可以响应的后端服务，/但我希望它在入口路由上运行myhost.com/overview。无论我尝试哪种配置，traefik 都不会删除路径/overview- 我可以看到后端正在获取/overview.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: registry-ingress
  namespace: ingress
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
    - host: myhost.com
      http:
        paths:
        - path: /overview
          pathType: Prefix
          backend:
            service:
              name: overview
              port:
                number: 8079

我尝试过几种变体：

traefik.ingress.kubernetes.io/rewrite-target: /$1
...
        - path: /overview(.*)

但这些会导致入口/overview请求未到达后端时出现 404。

总之，我想https://myhost.com/overview/访问后端/。

Traefik 不支持traefik.ingress.kubernetes.io/rewrite-target注释。请参阅此处的可用注释列表： https://doc.traefik.io/traefik/routing/providers/kubernetes-ingress/#annotations

但使用StripPrefix中间件可以实现您的目标。
