-====== Step 1 - Set up the Host ======
-You will need to set up a large-ish Ubuntu system. This will be home to the Oracle VirtualBox virtual machines (VM's). You can use any Ubuntu system, but you get points for using a NUC. This system will also be the Ansible controller for this lab.
-====== Install Ubuntu 20.04 Desktop ======
-// See [[https://ubuntu.com/tutorials/install-ubuntu-desktop#1-overview|Tutorial: Install Ubuntu Desktop]] //
-It's a good idea to use a "minimal installation" of Ubuntu for this Lab.
-====== Update and Install Packages ======
-Once installation is complete, follow best practice to upgrade software packages on the system. Open Terminal and enter the commands below.
-<code bash>
-sudo apt update
-sudo apt upgrade -y
-</code>
-Enable ssh so you can SSH to this system. Open Terminal and enter the commands below.
-<code bash>
-sudo apt update
-sudo apt install openssh-server -y
-</code>
-// See [[https://linuxize.com/post/how-to-enable-ssh-on-ubuntu-20-04/|Tutorial: Enable SSH]] //
-Install Ansible
-Add repository for Ansible
-sudo apt-add-repository ppa:ansible/ansible
-Install required packages
-sudo apt update && sudo apt upgrade -y
-sudo apt install vim p7zip xorriso ansible python3-passlib -y
-Create the user ansible and switch to the user (learn more at this link)
-sudo useradd -m -s /bin/bash ansible
-sudo passwd ansible
-su - ansible
-Give user ansible sudo permissions
-From your regular login account all the ''ansible'' user to the ''sudo'' group.
-<code>sudo usermod -aG sudo ansible</code>
-You can new test sudo access for the user ''ansible'':
-  * ''su - ansible''
-  * ''sudo apt update''
-For the remainder of the Lab you will be using the ''ansible'' user. You may conveniently ssh to your server as user ''ansible''.
-Create ssh key used to connect to the VMs
-Create the ssh key ansible will use to connect to your VMs
-ssh-keygen -o
-accept default settings and do not enter a passphrase
-Use cat ~/.ssh/id_rsa.pub to get your public key
-Looks like
-<code>ssh-rsa

-Save this key - you will use it when you create the custom Ubuntu ISO
-install oracle virtualbox using ansible
-Follow steps here: Install Oracle VirtualBox using Ansible
-Note: There are many references out there if you don't want to use Ansible to install VirtualBox (e.g., https://linuxconfig.org/install-virtualbox-on-ubuntu-22-04-jammy-jellyfish-linux)
