所以我有一些奇怪的问题与docker-machine。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该守护进程。通过设置DOCKER_OPTS选项来标记我的不安全的Nexus docker注册表，我能够成功地推送/拉动本地Ubuntu安装（没有docker-machine）。我试图在我的Mac OS上实现相同的最终目标。到目前为止，我已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 --
engine-insecure-registry mynexusrepo.cloudapp.net:18443 --engine-insecure-registry mynexusrepo.cloudapp.net:18444 --engine-insecure-registry mynexusrepo.cloudapp.net:18445 dev

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命令工作，因为它在我的直接Ubuntu操作系统上安装了docker工作正常。还有其他我想念的东西吗？我试过关闭所有终端，删除所有的docker-machines，重启等等。
谢谢！
