如何解决当我使用 traefik 启动许多 docker-compose 时，我的子网发生了变化
你好，
我想要几个使用 Docker-compose 和 Traefik 反向代理的 wordpress 实例。 我的每个 docker-compose 包括：
- 一个 wordpress 容器
- 一个 PhpMyAdmin 容器
- 一个 MySQL 容器
我的 Traefik 容器允许我对不同的 Web 容器使用自动 https 加密并且它可以工作。 我也可以毫无问题地启动 2 个 Wordpress 实例。
只有当我启动我的第三个 docker-compose 时，我的容器的子网被更新并且不再正确配置，这导致了我的网络问题。我的一些容器变得无法访问。
我不明白这个子网更改的原因。
我与你分享我的不同文件希望你能帮助我
谢谢大家！
