我在使用 traefik 设置 mailcow 时遇到问题，我遇到网关超时。我对 nextcloud 也有这个问题，所以我真的很感兴趣，是什么导致了网关超时这些问题。

我想这与端口 9000 和 php-fpm 上游或某事有关。

但我想确定，以及如何处理它。

我的traefik.toml：

debug = true
checkNewVersion = true
defaultEntryPoints = ["http", "https"]

[web]
address = ":8080"
[web.auth.basic]
users = ["admin:undecipherablestring"]

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

[acme]
email = "email@address.com"
storage = "acme.json"
entryPoint = "https"
onHostRule = true

[[acme.domains]]
  main = "main.com"
  sans = ["monitor.main.com", "ports.main.com", "git.main.com", "cloud.main.com", "mail.main.com"]

我想我可能遇到了与您正在/正在经历的类似的问题。看看这个 GitHub 问题：https ://github.com/containous/traefik/issues/979

如果你的问题和我的一样，那么问题来了：

Traefik 位于“前向”网络上，您的一项服务也是如此，但该服务也是“后向”网络的一部分。默认情况下，Traefik 不知道将请求发送到哪个网络......因此它将它们发送到随机选择的两个 IP 地址选项之一（在创建该容器时选择）。如果 Traefik 不是该网络的一部分，它将无法访问该容器，并且会给您一个网关超时。

解决方案：在你的容器中添加一个标签，直接向 Traefik 指定它应该在哪个网络上通信：

 labels:
      - "traefik.enable=true"
      - "traefik.docker.network=<folder prefix>webgateway"
      - "traefik.backend=<backend service"
      - "traefik.frontend.rule=Host:<host setting>"

专业提示：用于docker network ls确定网络的实际名称是什么，因为它不是 docker-compose 在文件中所说的。实际的网络名称是根据运行它的文件夹的名称作为前缀的。（我不知道为什么，我也不喜欢它，但这就是我们生活的世界）

因此<folder prefix>在我上面的例子中。

我所做的是在与项目名称的变量.env相同的目录中调用的文件中定义docker-compose.yml（以所有容器/网络/等的前缀结尾）。它应该只包含字符，不能包含空格、破折号等。

COMPOSE_PROJECT_NAME=myproject

然后，在您的应用程序标签中，您使用附加了由“_”分隔的已创建网络的变量名称：

 - "traefik.docker.network=${COMPOSE_PROJECT_NAME}_mynetwork"

FWIW，如果您在 traefik 服务定义的 provider 部分中定义网络，则无需将其添加到您以后添加的每个服务中。

例子：

version: "3.3"

services:
  traefik:
    image: "traefik:v2.2"
    container_name: "traefik"
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.network=traefik"     <=========
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
    ports:
      - "80:80"
      - "8090:8080"
    networks:
      - traefik
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"

    networks:
      traefik:
        external: true

您应该在撰写文件之外创建 traefik 网络。
