我正在尝试Github代码空间，特别是“Node.js & Mongo DB”默认设置。
端口被转发，我的目标是连接在我的本地机器上运行的MongoDB Compass。
转发到27017的地址类似于https://<long-address>.githubpreview.dev/

我的尝试

我尝试使用以下连接字符串，但它在MongoDB compass中不起作用。它在No addresses found at host中失败。我实际上不确定我如何确定MongoDB是否实际上在Github代码空间中运行？

mongodb+srv://root:example@<long-address>.githubpreview.dev/

.devcontainer文件

docker-compose.yml

和devcontainer.json文件

最后是Docker文件：

更新我也在MongoDB社区发布了here，但是没有帮助...
