-====== 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 22.04 Desktop ======
-The first step is to install Ubuntu 22.04 Desktop on the host system. It's a good idea to use a "minimal installation" of Ubuntu for this Lab. If you need help with this step, see the tutorial below.
-// See [[https://ubuntu.com/tutorials/install-ubuntu-desktop#1-overview|Tutorial: Install Ubuntu Desktop]] //
-====== 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>
-Next we will add the ppa:ansible repository and install a number of packages.
-<code bash>
-sudo apt-add-repository ppa:ansible/ansible
-sudo apt update
-sudo apt install openssh-server vim ansible p7zip xorriso ansible python3-passlib -y
-</code>
-You should now be able to ssh to your host.
-// See [[https://linuxize.com/post/how-to-enable-ssh-on-ubuntu-20-04/|Tutorial: Enable SSH]] //
-====== Configure the ansible User and Generate Keys ======
-  - Create the user ansible and give sudo permission (and enter a password for the user when prompted)
-    * <code>
-sudo useradd -m -s /bin/bash ansible
-sudo usermod -aG sudo ansible
-sudo passwd ansible
-</code>
-    * // See [[https://linuxize.com/post/how-to-create-users-in-linux-using-the-useradd-command/|How to Create Users in Linux (useradd Command)]] //
-  - Test the new user
-    * From your regular login switch to the ''ansible'' user
-      * ''su - ansible''
-      * Enter the password
-      * ''sudo uptime''
-      * exit
-    * Test connecting to your host via SSH with user ''ansible''
-    * For the rest of the lab, we will be logged in as the ''ansible'' user
-  - Create Keys for Ansible Management
-    * Ensure you are logged as the user ''ansible''
-    * <code>ssh-keygen -o</code>
-    * __Do not__ enter a passphrase
-    * View the public key and __save it for a later step__
-      * <code>cat ~/.ssh/id_rsa.pub</code>
-      * It will look like this:
-        * <code>ssh-rsa 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 ansible@labbox</code>
-====== 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]])
-Run the following playbook to install VirtualBox.
-<file yaml install-virtualbox.yml>
----
-- hosts: localhost
-  connection: local
-  become: true
-  tasks:
-    - name: Add Oracle apt key
-      apt_key:
-        url: https://www.virtualbox.org/download/oracle_vbox_2016.asc
-        state: present
-    - name: Add Virtualbox repo
-      apt_repository:
-        repo: "deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian {{ ansible_distribution_release }} contrib"
-        state: present
-    - name: Install Virtualbox
-      apt:
-        pkg:
-          - virtualbox
-        state: present
-        update_cache: true
-    - name: Ensure vboxdrv kernel module is loaded (optional)
-      modprobe:
-        name: vboxdrv
-        state: present
-</file>
-Run as <code>ansible-playbook install-virtualbox.yml --ask-become-pass</code>
-Enter the password for the user ''ansible'' when prompted.
-====== Restart the Host ======
-Run ''sudo reboot'' and wait for the host to reboot.
-====== Next Step ======
-Continue to [[Step 2 - Deploy the VMs]]
-Or back to [[lab:kubernetes_app:start|Start]]
