Traefik v2和路径路由

Question

我尝试过：

  traefik:

      - --log.level=DEBUG                                                               
    ports:

    image: "nginx:alpine"

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

我在docker swarm中使用此堆栈。我的问题是，当我尝试访问 nginx.traefik.kb / ng 时，我从nginx获得404。有了whoami图片和URL whoami.traefik.kb / who ，我没有任何问题，并且 nginx2.traefik.kb 都没有...

我只有这个配置文件，没有traefik.yml左右。

有什么想法吗？谢谢！

已解决！

添加此内容：

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

有了这个，我无法进入http://example.com/ng并开始运行nginx
