Technical requirements

The learning environment for this chapter will be represented by a single virtual machine deployed through Vagrant on VirtualBox. You will need the following minimal configuration in order to support the environment:

CPU	RAM, GiB	OS
2 cores with HT enabled	6	Fedora 26/CentOS 7/RHEL 7

The VM will be about 3 GB in size, so make sure that you have enough free space on your /home partition, or change the location of the directory where VirtualBox stores the VM's files in the File | Preferences | General | Default Machine folder.

The Vagrantfile that can be used for deploying our VM may look similar to the following:

$ cat Vagrantfile
Vagrant.configure("2") do |config|
  config.vm.box = "centos/7"
  config.vm.hostname = "openshift.example.com"
  config.vm.provider "virtualbox" do |v|
    v.memory = 4096
    v.cpus = 4
  end
  config.vm.network "private_network", ip: "172.24.0.11"
end

Note

As all OpenShift services in this chapter will be deployed on a single VM, we will provide it...
