安装

Docker

$ sudo docker run -d --name "origin" \
        --privileged --pid=host --net=host \
        -v /:/rootfs:ro -v /var/run:/var/run:rw -v /sys:/sys -v /sys/fs/cgroup:/sys/fs/cgroup:rw \
        -v /var/lib/docker:/var/lib/docker:rw \
        -v /var/lib/origin/openshift.local.volumes:/var/lib/origin/openshift.local.volumes:rslave \
        openshift/origin start
$ sudo docker exec -it origin bash

macOS

使用Homebrew

$ brew cask install minishift
$ brew cask install --force minishift

其它

Minikube Run Kubernetes locally
Minishift Run OpenShift locally

使用Minishift快速部署，使用xhyve hypervisor启动本地OpenShift集群。

$ brew install --HEAD xhyve
$ brew cask install minishift
$ brew install docker-machine-driver-xhyve
$ sudo chown root:wheel $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
$ sudo chmod u+s $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
$ minishift start
$ minishift ip
$ minishift oc-env
$ oc new-app https://github.com/openshift/nodejs-ex -l name=myapp
$ oc logs -f bc/nodejs-ex
$ oc expose svc/nodejs-ex
$ minishift openshift service nodejs-ex --in-browser
$ minishift image list --vm
$ minishift addons list
$ minishift stop

或 OpenShift Origin Virtual Machine Deployment Guide

在一个空目录下：

$ vagrant init openshift/origin-all-in-one
$ vagrant up --provider=virtualbox

升级

$ vagrant up
$ vagrant box update --box openshift/origin-all-in-one
$ vagrant destroy --force 
$ vagrant up --provider=virtualbox

卸载

$ vagrant halt
$ vagrant destroy --force
$ vagrant box remove --force openshift/origin-all-in-one

下载oc，并加入path

oc version

之前版本安装步骤：

下载OpenShift Vagrant VirtualBox VM快速体验，可从百度云盘下载2.8G的镜像文件。

vagrant box add openshift3 openshift-bootstrap-1.1.box
vagrant up
vagrant ssh
passwd 
输入新密码，如：huihoo.io
oc version 
oc get svc
