多个docker使用traefik（v2.1）和数据库网络组合文件

我想建立一个码头景观。我使用一个带有traefik（v2.1）映像的容器和一个用于多个数据库的mysql容器

traefik/docker compose.yml

对于该结构，我希望通过多个docker compose文件控制所有项目。这些容器应与traefik容器在同一网络上运行，有些容器与mysql容器在同一网络上运行。 这也适用于以下情况（但只是有时）

当我在dev releases/via

docker compose up-d

中重新启动容器时，在浏览器中调用它们时会出现典型的错误“网关超时”。 只要我评论网络

networks:#-mysql

并在dev发行版中重新启动docker compose，它就会再次工作

我猜我没有正确配置外部网络。不能使用2个外部网络吗？ 我希望一些容器可以访问“mysql”网络，但它不应该可以访问整个traefik网络

如果您需要更多信息，请告诉我

编辑（26.03.2020） 我让它运行

我将所有容器放在一个网络“代理”中。看来mysql也必须在代理网络中

因此，我将以下内容添加到数据库/docker compose.yml

并从dev releases/docker compose.yml中删除数据库\u mysql network

根据文件名，您的

mysql

网络应该是

您还缺少一些服务标签，例如

traefik命令行

标签

- traefik.docker.network=proxy
- traefik.http.services.dev-releases-backend.loadbalancer.server.port=yourport
- traefik.http.routers.dev-releases-backend.service=mailcatcher

您可以查看更多信息

mysql网络是database\u mysql。我将目录mysql/更改为database/1。我真的需要swarm模式和负载均衡器吗？我的docker场景2从不需要使用swarm模式。为什么是docker.手表？3.你是说dev releases/docker compose.yml上的“-traefik.docker.network=proxy”吗？我自己在没有swarm的情况下修复了它。请参阅我的编辑。谢谢你的时间
