Question

我在API Designer上创建一个LoopBack项目（用于管理API和应用程序的IBM Toolkit），设置数据源，将其附加到模型并保存成功。通过选择DataPower Gateway Policies并单击“运行”按钮尝试在本地运行应用程序后，出现错误：

Service inventory started but did not initialize within the timeout period. Dumping log buffer.

此外，我已经检查了API Connect的预先要求：

node.js：v8.10.0 npm：v5.8.0 apiconnect：v5.0.8.2

Docker：

docker-py version: 3.1.4
CPython version: 3.6.4

此外，我已将Docker设置设置为4096MB RAM，2CPU并与C：\ Drive共享。

我已经搜索并阅读了类似的问题，但没有弄清楚确切的问题在哪里。请帮忙！

该错误表示应用程序无法连接到MySQL数据库。

如果您的数据库在本地计算机上运行，则需要更改连接字符串以访问Docker网关（通常为172.17.0.1）而不是localhost本身（这将是指向正在运行的docker容器的指针）。 / p>

如果MySQL正在其他地方运行，那么它可能已关闭，或者您遇到网络问题。

解决MySQL连接问题后，您的应用程序应该与其他组件一起启动。
