docker - Traefik + Nextcloud 导致网关故障

Question

我有 3 个服务已启动并正在运行。mariadb 和 nextcloud 实例:

version: '2.1'

volumes:
  nextcloud:
  db:

services:
  db:
    image: mariadb
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=my_root_password
      - MYSQL_PASSWORD=my_password
      - MYSQL_DATABASE=my_database
      - MYSQL_USER=my_user
  app:
    image: nextcloud
    restart: always
    networks:
      - web
      - default
    ports:
      - 9000
    labels:
      - "traefik.backend=app"
      - "traefik.docker.network=web"
      - "traefik.frontend.rule=Host:my_host"
      - "traefik.enable=true"
      - "traefik.port=9000"
      - "traefik.default.protocol=http"

networks:
  web:
    external: true

还有 traefik 服务:

version: '2'

services:
  traefik:
    image: traefik:1.5.4
    restart: always
    ports:
      - 80:80
      - 443:443
    networks:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /opt/traefik/traefik.toml:/traefik.toml
      - /opt/traefik/acme.json:/acme.json
    container_name: traefik

networks:
  web:
    external: true

此 traefik 实例正在使用此配置文件:

debug = false

logLevel = "ERROR"
defaultEntryPoints = ["https","http"]

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
  [entryPoints.https.tls]

[retry]

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "my_host"
watch = true
exposedByDefault = false

[acme]
email = "my_email"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
[acme.httpChallenge]
entryPoint = "http"

现在，当我转到我的主机时，它会重定向到 HTTPS，但随后它只显示 bad gateway 而没有其他内容。它应该显示 nextcloud Web 应用程序。有谁知道为什么会发生这种情况？我正在使用 docker-compose up -d 命令运行撰写文件。

现在可能为时已晚，但我自己也遇到了这个问题，所以发布一个答案来解决我的问题。
Nextcloud 在 Traefik 尝试连接的容器的 IP 地址上公开端口 80。因此，您错误地指定了“traefik.port”标签的端口。将其从 9000 更改为 80。
