traefik 和 php fpm 的网关超时
Gateway timeout with traefik and php fpm
我在使用 traefik 设置 mailcow 时遇到问题，遇到网关超时。我对 nextcloud 也有这个问题，所以我真的很感兴趣，是什么导致了这些网关超时问题。
我想这与端口 9000 和 php-fpm upstream 或某事有关。
但我想确切地知道，以及如何处理它。

我认为这个问题已经被 traefik 社区解决了。你可以检查这个：https://github.com/containous/traefik/pull/1873
我想我遇到的问题可能与您 are/were 遇到的问题类似。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，这里是问题所在：
Traefik 在 "front facing" 网络上，您的一项服务也是如此，但该服务也是 "back facing" 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两个 IP 地址选项中随机选择的一个（在创建该容器时选择）。如果 Traefik 不是该网络的一部分，它将无法到达该容器，并且会给您一个网关超时。
解决方案：向您的容器添加一个标签，以直接向 Traefik 指定它应该在哪个网络上进行通信：
labels:
- "traefik.enable=true"
- "traefik.docker.network=<folder prefix>webgateway"
- "traefik.backend=<backend service"
- "traefik.frontend.rule=Host:<host setting>"
专业提示：使用 docker network ls 找出网络的 实际 名称是什么，因为它不是 docker-compose 在文件。实际的网络名称是基于它所在的文件夹的名称作为前缀的运行。（我不知道为什么，我不喜欢它，但这就是我们生活的世界）
因此我上面的例子中的<folder prefix>。
我所做的是在与 docker-compose.yml 相同的目录中的名为 .env 的文件中定义项目名称的变量（以所有 containers/networks/etc 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，使用变量名附加创建的网络，并以“_”分隔：
- "traefik.docker.network=${COMPOSE_PROJECT_NAME}_mynetwork"
FWIW，如果您在 traefik 服务定义中的提供程序部分定义了网络，则无需将其添加到您以后添加的每个服务中。
示例：
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 compose 文件之外创建 traefik 网络。
我在使用 traefik 设置 mailcow 时遇到问题，遇到网关超时。我对 nextcloud 也有这个问题，所以我真的很感兴趣，是什么导致了这些网关超时问题。
我想这与端口 9000 和 php-fpm upstream 或某事有关。

我认为这个问题已经被 traefik 社区解决了。你可以检查这个：https://github.com/containous/traefik/pull/1873
我想我遇到的问题可能与您 are/were 遇到的问题类似。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，这里是问题所在：
Traefik 在 "front facing" 网络上，您的一项服务也是如此，但该服务也是 "back facing" 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两个 IP 地址选项中随机选择的一个（在创建该容器时选择）。如果 Traefik 不是该网络的一部分，它将无法到达该容器，并且会给您一个网关超时。
解决方案：向您的容器添加一个标签，以直接向 Traefik 指定它应该在哪个网络上进行通信：
labels:
- "traefik.enable=true"
- "traefik.docker.network=<folder prefix>webgateway"
- "traefik.backend=<backend service"
- "traefik.frontend.rule=Host:<host setting>"
专业提示：使用 docker network ls 找出网络的 实际 名称是什么，因为它不是 docker-compose 在文件。实际的网络名称是基于它所在的文件夹的名称作为前缀的运行。（我不知道为什么，我不喜欢它，但这就是我们生活的世界）
因此我上面的例子中的<folder prefix>。
我所做的是在与 docker-compose.yml 相同的目录中的名为 .env 的文件中定义项目名称的变量（以所有 containers/networks/etc 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，使用变量名附加创建的网络，并以“_”分隔：
- "traefik.docker.network=${COMPOSE_PROJECT_NAME}_mynetwork"
FWIW，如果您在 traefik 服务定义中的提供程序部分定义了网络，则无需将其添加到您以后添加的每个服务中。
示例：
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 compose 文件之外创建 traefik 网络。
