docker - 如何在docker中使用traefik代理后端

Question

我正在使用traefik和docker compose设置前端和后端，如下所示:

version: "3.7"
services:
  frontend:
    image: frontend:tag
    networks:
      - traefik-network
    labels:
      - traefik.enable=true
      - traefik.port=80
      - traefik.docker.network=traefik-network
      - traefik.http.routers.frontend.entrypoints=web
      - traefik.http.routers.frontend.rule=PathPrefix(`/`)

  backend:
    image: backend:tag
    networks:
      - traefik-network
    labels:
      - traefik.enable=true
      - traefik.port=3000
      - traefik.docker.network=traefik-network

reverse-proxy:
    image: traefik:v2.0
    networks:
      - traefik-network
    labels:
      - traefik.docker.network=traefik-network
      - traefik.enable=true
    command:
      - --log.level=DEBUG
      - --api.insecure=true
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entryPoints.web.address=:80
      - --entryPoints.name.forwardedHeaders.insecure=true
    ports:
      - "80:80"
      - "3000:3000"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

networks:
  traefik-network:
    name: traefik-network

以前我使用nginx从FE到BE创建代理，就像这样

upstream go_backend {
  server backend:8085 max_fails=3 fail_timeout=50;
}

location /api/ {
   proxy_pass http://go_backend/;
}

如何使用traefik v2将来自FE的请求代理到BE？
没有toml文件。

您期望得到什么结果:
当我转到本地主机时，来自服务器的请求将转发到后端:3000。

现在会发生什么:
当我转到本地主机时，请求未到达后端。

对于处于同一职位的任何人:

 - traefik.docker.network=traefik-network
 - traefik.http.routers.backend.entrypoints=backend

请记住为您的服务设置入口点: - traefik.http.routers.<s-name>.entrypoints=<s-name>
