OpenShift Installation - All-in-One Box

VirtualBox is basically inception of your computer. A VirtualBox or VB is a software virtualization package that installs an operating system as an application. This allows additional operating system to be installed on it as a Guest and run in an virtual environment. 

Vagrant is a software that is used to manage a development environment. Using this tool from a command line we can grab any available OS, install, configure, run and work inside it. The first thing to create a development environment is by creating a vagrant file or by downloading a vagrant box. 

To create a Ose all-in-box , lets create a Vagrantfile as below, 

[root@testing-machine vagrant]# cat Vagrantfile 

Vagrant.configure("2") do |config| 

   config.vm.box = "openshift/origin-all-in-one" 

end 

  

Save the file and run “vagrant up” command as below, 

[root@testing-machine vagrant]# vagrant up 

It will take some time to download a Ose all-in-one box and start the machine. Once the machine is up and running, we can  

  

 Once the box has deployed, you can log in using admin and a password, as follows: 

$ oc login 

Server [https://localhost:8443]: 

The server uses a certificate signed by an unknown authority. 

You can bypass the certificate check, but any data you send to the server could be intercepted by others. 

Use insecure connections? (y/n): y 

  

Authentication required for https://localhost:8443 (openshift) 

Username: admin

You have access to the following projects and can switch between them with 'oc project <projectname>': 

      cockpit 

*    default 

      kube-system 

      openshift 

      openshift-infra 

  

Using project "default". 

Welcome! See 'oc help' to get started.
