虚拟化支持:

• OS X: xhyve (default), VirtualBox, VMware Fusion
• GNU/Linux: KVM (default), VirtualBox
• Windows: Hyper-V (default), VirtualBox

本文所述过程全部在MacOS X环境下完成

启动

命令行和参数

$ minishift start --vm-driver=virtualbox

由于总所周知的原因, 可以使用Docker镜像

$ minishift start --vm-driver=virtualbox --registry-mirror=https://docker.mirrors.ustc.edu.cn

参数 --vm-driver 可用的值有: virtualbox, vmwarefusion, xhyve (默认为xhyve), 由于我的系统上已经安装了VirtualBox, 因此选择 virtualbox, --registry-mirror指定了公共Docker镜像库的地址.

输出

OpenShift server started.

如果过程中出现任何错误, 执行 minishift delete 删除集群然后重试, 启动过程中会下载镜像库等资源, 保持良好的网络连接.

把 oc 命令添加到PATH中

使用minishift oc-env输出要添加到PATH中的export命令:

export PATH="/Users/username/.minishift/cache/oc/v3.6.0:$PATH"
# Run this command to configure your shell:
# eval $(minishift oc-env)

应用部署

部署一个简单的Node.js应用

$ oc new-app https://github.com/openshift/nodejs-ex -l name=myapp
