c# - 当我使用 Docker 将 ABP 发布到 Ubuntu 时，无法连接到任何指定的 MySQL 主机

Question

我尝试使用 Docker 将 My Asp Boilerplate 项目发布到 Ubuntu，但遇到了问题。无法连接到任何指定的 MySQL 主机。

--- End of stack trace from previous location where exception was thrown ---

这是我的连接，

 {
      "ConnectionStrings": {
        "Default": "Server=128.199.250.219; Database=CityInfoDb; User Id=****; Password=******;"
      },
      "App": {
        "WebSiteRootAddress": "http://localhost:9903/"
      }
    }

我的 Docker 文件，

mysql ,

也许我的 dockerfile 不正确，请帮助我，我很沮丧。

您的连接字符串似乎不正确，请在示例下方查找。

{

"ConnectionStrings": {
"Default": "server=127.0.0.1;uid=root;pwd=1234;database=mysqldemodb"
},
 ...
}

您可以参考EF Core MySql 集成。
