Kubernetes入口中基于Traefik路径的路由无法按预期工作

Question

我正在尝试使用Kubernetes中Traefik入口 Controller 提供的基于路径的路由机制，但URL重写存在一些问题。

我的[更新]配置如下

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/auth-type: "basic"
    traefik.ingress.kubernetes.io/auth-tls-insecure: "true"
    traefik.ingress.kubernetes.io/frontend-entry-points: "http,https"
    traefik.ingress.kubernetes.io/app-root: "/"
    traefik.ingress.kubernetes.io/rule-type: "PathPrefixStrip"
    traefik.ingress.kubernetes.io/rewrite-target: "/"
  name: webapp-ingress
  namespace: my-company
spec:
  rules:
   - host: local-ubuntu
   - http:
      paths:
      - path: /
        backend:
          serviceName: webapp
          servicePort: 80
      - path: /db
        backend:
          serviceName: db-manager
          servicePort: 8081

流量被路由到正确的服务，但是当我查看db-manager(kubernetes)服务的日志时，URL仍带有/db前缀。
我对PathPrefixStrip的期望是，将在没有/db前缀的情况下将流量路由到运行db-manager微服务的容器，该容器正在后端监听/( http://db-manager:8081)。

我想念什么吗？ traefik或仅nginx支持它吗？
预先感谢您的反馈。

更具体地说，我将在下面讨论的当前注释中观察以下内容

traefik.ingress.kubernetes.io/规则类型:“PathPrefixStrip”

traefik.ingress.kubernetes.io/rewrite-target:“/”

网址: http://local-ubuntu/db [确定]-> 200

然后正在加载其他资源，但指向错误的基本URL

例子:

资源网址为: http://local-ubuntu/public/css/bootstrap.min.css

但这应该是: http://local-ubuntu/db/public/css/bootstrap.min.css
(当我手动尝试时可以使用)

我不确定当前配置中缺少的内容。

关于不提供静态内容，文档指出以下内容:

Use a *Strip matcher if your backend listens on the root path (/) but should be routeable on a specific prefix. For instance, PathPrefixStrip: /products would match /products but also /products/shoes and /products/shirts. Since the path is stripped prior to forwarding, your backend is expected to listen on /. If your backend is serving assets (e.g., images or Javascript files), chances are it must return properly constructed relative URLs. Continuing on the example, the backend should return /products/shoes/image.png (and not /images.png which Traefik would likely not be able to associate with the same backend). The X-Forwarded-Prefix header (available since Traefik 1.3) can be queried to build such URLs dynamically.
