Docker service laravel app not 运行 when not 运行 in manager node
Docker service laravel app not running when not running in manager node
docker-compose.yml
这是我的 docker-compose 文件，用于使用 docker-堆栈在多个实例中部署服务。如您所见，app 服务是 2 个节点中的 laravel 运行ning 和其中一个节点中的数据库 (mysql)。

我面临的问题
1. 虽然服务处于 运行ning 状态，但当我检查服务日志时，我可以看到只有一个节点的迁移成功，而不是 运行宁在另一个节点。 查看下面的日志
- 当我仅在 管理器节点 中创建 app 服务 运行 时，应用程序运行良好。我可以登录页面并执行所有操作，但当我在任何节点中使用副本创建应用程序服务 运行 时，登录页面会显示，但当尝试登录时，它会重定向到 NOT FOUND 页面
这是尝试在 3 个节点上 运行 时的完整日志。下面是在 2 个节点上 运行ning 时的示例。您可以详细查看迁移问题

I don't know if its due to migration problem or what. Sometime I can
login and after few time I get redirected to Not found page again when
clicking on the link inside dashboard.
所以我 运行 您的服务并发现了一些问题。
- mysql 中
docker-compose.yml 中的用户不同。这可能只是为了发布目的
- 在您的
Dockerfile 中，您使用了 ENTRYPOINT，这导致在迁移服务上也对 运行 执行了相同的命令。我改成了CMD
- 您没有 运行
migration 服务与您的 mysql 数据库在同一网络中。所以 mysql 无法从同一个访问。
这是我使用的最终合成文件
