What you should know
- [Instructor] As the Red Hat EX294 certification covers technologies included in Red Hat Enterprise Linux 8. We'll be using a version of that operating system for this course. In this course when I use the generic term Enterprise Linux 8 I mean Red Hat Enterprise Linux 8 or any other direct clone such as CentOS 8 Enterprise Linux. Anything we do in this course will work fine on either of these operating systems. Since the certification focuses on Ansible Engine, most of the course could also be done without modification on Fedora Linux or any spin of Fedora as well. Furthermore, most of the technologies covered in this course are not distribution specific and focus on IT automation using Ansible. As such, they can be applied to any operating system utilizing Ansible Engine for automation. For this course we'll be using Linux in VirtualBox virtual machines. There are versions of VirtualBox for Windows, macOS, Solaris and Various Linux distributions. For this course I'll be running VirtualBox on a Linux host. In order to run virtual machines for this course, you'll need a computer with an Intel or AMD 64-bit CPU with virtualization support. Intel CPUs with virtualization support will be advertised as having VT-x and AMD calls it AMD-V. You will also need a 64-bit host OS. If you're using Linux this is automatic. If you're using Windows make sure you have a 64-bit of that operating system. If you're OS is 64-bit then you'll want to download the 64-bit version of VirtualBox as well. For this course you may also want to have high-speed internet for downloading ISO images. And doing Linux operating system software updates. You will also want to have 20 to 25 gigabytes of free hard drive space minimum. This will provide enough space for two CentOS 8 Linux guest VMs. If you have more free space available it could give you more flexibility for creating additional guest VMs or giving your VMs larger virtual hard drives. To run more than one VM at a time you'll need to have two to four gigabytes of free system memory if you're using Linux as your host OS. If you're using Windows as the host OS, I recommend eight gigabytes of RAM minimum. The foundation course in this three part Red Hat EX294 series is Cert Prep Red Hat Certified Engineer EX294 Foundations of Ansible. In that course we install a 64-bit version of VirtualBox. Install CentOS 8 Linux in a VirtualBox virtual machine. And set up our VirtualBox lab environment. Including installing VirtualBox guest additions in CentOS. Making a clone of our CentOS 8 VM. As well as managing VirtualBox networking with NAT in a private network. If you haven't taken that course yet, you'll want to do that before proceeding with this one for the best user experience. If you already have foundational knowledge of Ansible you may want to just watch the videos for CentOS 8 installation, VirtualBox lab set up as well as the videos to install Ansible on the control node, preparing to manage nodes and building static inventory. Those videos will get you started for this course.
