docker install 无法连接数据库

[leona0918]

使用docker 安装，运行 docker-compose up命令后 log 信息如下：

如何确定数据库正确连接？

[lxerxa]

应该是宿主主机机内存太小了。

应该是宿主主机机内存太小了。

本地环境win10 64位，8G内存。应该不是内存小的原因吧

[leona0918]

我的主机环境是win10 enterprise, 安装了docer for windows10, 启动MongoDB 一直有问题，在网上看到一个说法：
需要使用-v参数来加载（mount）一个磁盘目录（volume）的时候，就会出现问题，至少我在MongoDB中使用-v参数来将MongoDB的数据文件映射到主机目录时，就会导致MongoDB无法正常启动。这个问题在Hyper-V出现之前，在Virtual Box时代就有，而且根据社区的讨论，似乎在Hyper-V的版本中也还是没有解决。详细信息可以参考这里：https://stackoverflow.com/questions/42756776/how-do-i-configure-mongo-to-run-in-docker-to-using-an-external-drive-on-windows。
现在切换到ubuntu
