Question

我正在尝试在单个主机上托管2个具有相同控制台图像的容器，这些容器指向不同的环境，并使用Traefik容器路由至它们。问题是，无法访问第二个容器。我不断收到错误的网关。

使用第二个容器的端口导航到IP失败，但是端口映射配置似乎正常。第二个容器中没有日志。

docker-compose

  console:
    container_name: console
    image: REDACTED
    environment:
      API_URL: "REDACTED-PRD"
    ports:
      - 4200:4200
    labels:
      - traefik.port=4200
      - traefik.frontend.rule=Host:dev.REDACTED.com
  console-prd:
    container_name: console-prd
    image: REDACTED
    environment:
      API_URL: "REDACTED-DEV"
    ports:
      - 4300:4200
    labels:
      - traefik.port=4300
      - traefik.frontend.rule=Host:app.REDACTED.com
  traefik:
    container_name: traefik
    image: traefik:1.7.10-alpine
    ports:
      - 80:80
      - 443:443
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik.toml:/etc/traefik/traefik.toml:Z```

ipaddr:4300 gets bad gateway. Traefik logs:

Answer 1

traefik端口在标签中也应为4200。 Traefik没有使用已发布的端口

单个主机上有多个Docker化的angular应用
