为什么Keyclock和SQL的容器在手动关闭后不启动?

Question

重启后，当我尝试使用Portainer启动容器时，我在keyclock日志文件中看到以下错误。

{

("subsystem" => "undertow"),
("server" => "default-server"),
("host" => "default-host")

经过调查，我发现sql server已经关闭，当我启动这个程序时，我看到以下错误:

我试着通过Portainer和docker-compose文件运行这个。任何建议都会很有用的。

我创建了一个新的容器数据库链接到SQL容器。在现有数据库中，用户名:admin已经从先前的安装中创建。当我创建新的容器，并与旧数据库链接，它显示错误，因为相同的名称"admin"是已经存在的。解决方案:在我的yml文件中，我将用户名从"admin"admin1"帮助"。容器已启动并运行。
