The learning environment for this chapter consists of two VMs with the following characteristics:
| Hostname | RAM | vCPU | OS |
| openshift.example.com | 4 GB | 2 | CentOS 7 |
| storage.example.com |
2 GB |
1 | CentOS 7 |
These machines can be deployed anywhere (bare metal, VMware, OpenStack, AWS, and so on). However, for educational purposes, we recommend using the Vagrant + VirtualBox/libvirt configuration to simplify the process of deployment and re-deployment of our virtual environment.
