Develop On Openshift on your Windows 10 Laptop
As part of our Work we install and configure Openshift. We offer full solutions from installation through the Devops pipeline.
I have found that using minishift with VirtualBox to be the easiest Proof of Concept as well as the ability to develop applications and Infrastructure as a service. I found it easiest to fiddle with OKD to be able to simply create projects for R & D.
Install Oracle Virtual box
Download Minishift
https://docs.okd.io/latest/minishift/getting-started/preparing-to-install.html
download the Windows AMD 64 latest, It works with Intel also, from https://github.com/minishift/minishift/releases
Now run the minishift with your previously installed VirtualBox
Run:
.\minishift start –vm-driver=virtualbox
You Should see output similar to the following:
PS C:\Users\Steve\Downloads\minishift-1.34.0-windows-amd64\minishift-1.34.0-windows-amd64> .\minishift start –vm-driver=virtualbox

Server Information …
OpenShift server started.The server is accessible via web console at:
https://192.168.99.103:8443/consoleYou are logged in as:
User: developer
Password: <any value>To login as administrator:
oc login -u system:admin— Exporting of OpenShift images is occuring in background process with pid 11844.
You can now create project via the GUI from:
https://YOUR_IP_ADDRESS:8443/console
You can create Openshift projects and even open the Openshift GUI in your broswer:
As instructed login to the GUI with user system and password admin
In order to be able to create projects from the CLI, you need the oc and kubectl execubles.
Run:
minishift oc-env
This will show you something like
PS C:\Users\Steve\Downloads\minishift-1.34.0-windows-amd64\minishift-1.34.0-windows-amd64> .\minishift.exe oc-env
$Env:PATH = “C:\Users\Steve\.minishift\cache\oc\v3.11.0\windows;$Env:PATH”
# Run this command to configure your shell:
# & minishift oc-env | Invoke-Expression
PS C:\Users\Steve\Downloads\minishift-1.34.0-windows-amd64\minishift-1.34.0-windows-amd64>
You can also download the exectubles and be able to run any Openshift project that you have access to.
Then run as it says:
& minishift oc-env | Invoke-Expression
Now you should be able to run the oc and kubectl commands which are central to Openshift.
Download Openshift OC and minikube windows exectubles
You can open them and run a powershell from that dir, even add it to your path
When the installation gets stuck you can run
.\minishift.exe delete
https://docs.okd.io/latest/minishift/getting-started/uninstalling.html
From within a Centos 7 VM, after installing docker you can run Openshift Origin in a VM
To get started I ran the following command. Next time for security I will get it to run NOT as root, but this will do for now as POC Proof of Concept
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
This is formerly called Origin
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
To use only Virtualbox as your VM run:
.\minishift.exe config set vm-driver virtualbox
