Traefik v2 和带路径的路由

Question

我试过这个：

  traefik:

      - --log.level=DEBUG                                                               
    ports:

  nginx:                                                                                
    image: "nginx:alpine"

      - "traefik.http.services.nginx2.loadbalancer.server.port=80" 

我在 docker swarm 中使用这个堆栈。我的问题是当我尝试访问nginx.traefik.kb/ng 时，我从 nginx 得到 404。使用 whoami 图像和 url whoami.traefik.kb/who我没有任何问题，使用nginx2.traefik.kb也没有...

我只有这个配置文件，没有 traefik.yml 左右。

有任何想法吗？？谢谢！！

解决了！

添加这个：

  - "traefik.http.middlewares.nginx-prefix.stripprefix.prefixes=/ng"
  - "traefik.http.routers.nginx.middlewares=nginx-prefix"

有了这个，我不能去http://example.com/ng并让 nginx 运行
