所以我对 docker-machine 有一些奇怪的问题。我正在尝试在我的 Mac OS El Capitan 上设置一个 docker-machine，并且还为一些不安全的注册表标记了守护进程。通过设置 DOCKER_OPTS 选项来标记我不安全的 Nexus docker 注册表，我能够成功地推/拉本地 Ubuntu 安装（没有 docker-machine）。我正在尝试在我的 Mac OS 上实现相同的最终目标。到目前为止，我已经使用默认安装安装了 Docker Toolbox，并在终端中尝试了以下操作。
Vinays-MacBook-Pro:~ Vinay$ sudo docker-machine create --driver virtualbox --

Vinays-MacBook-Pro:~ Vinay$ docker-machine -version
docker-machine version 0.4.1 (e2c88d6)
所以我知道 sudo docker pull mynexusrepo.cloudapp.net:18445/docker-thirdparty/mongodb:3.0.2 命令可以正常工作，因为它在我的直接 Ubuntu 操作系统上运行良好，安装了 docker。还有什么我想念的吗？我尝试关闭所有终端，删除所有 docker-machines，重新启动等。
谢谢！
