Disclaimer:

It is expected that you have Vagrant and Virtualbox installed on your host machine (whether the host is Windows, Linux or OSX). If not, then please download/install Vagrant and Virtualbox.

2. Virtualizing ubuntu2004 on Vagrant

This section covers easy to use steps to get started with downloading and virtualizing ubuntu2004 virtual environment.

2.1. Single Machine Mode:

Single Machine mode is a mode where you will only be initializing a fresh vagrant virtual envrionment to useubuntu2004. Open CMD (for Windows host) or Terminal (for Linux/OSX host), then change to a directory of your liking on the Command Prompt or Terminal and run the following command:

vagrant init darkwizard242/ubuntu2004

Now that Vagrantfile has been created for ubuntu2004, you can initialize/boot up the box (it will download the box if not already downloaded) using the following command:

vagrant up

Once the box is up, do vagrant ssh and you will be within the virtualized box.

2.2. Multi Machine Mode:

As per Vagrant's website, "Vagrant is able to define and control multiple guest machines per Vagrantfile. This is known as a 'multi-machine' environment." So if you are running in a multi-machine mode, you can simple add the following chunk within the existing Vagrantfile:

config.vm.define "myubuntubox" do |myubuntubox|
   myubuntubox.vm.box = "darkwizard242/ubuntu2004"
   myubuntubox.vm.hostname = 'focalfossa.ubuntu.com'
end

Now run the following command so that the box can be downloaded (if not already) and be booted up:

vagrant up mydevopsbox

Once the box is up, do vagrant ssh mydevopsbox and you will be within the virtualized box.

3. Users - for ubuntu2004 Vagrant box

Like any other vagrant box, you can easily ssh into ubuntu2004 using the default vagrant ssh (if using as a single machine mode) command or vagrant ssh myubuntubox if using in a multi machine mode.

3.1. Type and list of users and passwords:

Below is table listing the type of users as well as their usernames and passwords:

User Type	Username	Password
System User	vagrant	password

NOTE: Though, the password for vagrant user has been set by default by me so that anyone can use it easily. Feel free to change the password using the following command:

• passwd vagrant

3.2. Users and permissions:

Following users have already been added as sudoers with privileges to perform desired operations without supplying passwords:

root@ubuntu2004:~$ grep -i vagrant /etc/sudoers
vagrant ALL=(ALL) NOPASSWD: ALL

3.3. Users and home directories:

Following table consists the system users and their $HOME directories.

User	Home Directory
root	/root
vagrant	/home/vagrant

4. ubuntu2004 Build & Testing:

Vagrant box ubuntu2004 can be built using Packer. Pre-requisites include Virtualbox as that is the builder being used for the packer build.

4.1. Building out your own customized ubuntu2004:

Assuming that Virtualbox and Packer are installed on the host system with internet accessibility, you can build ubuntu2004 yourself using the following steps:

1. Downloading ubuntu2004 source code archive: wget -O vagrant-ubuntu-20.04.zip https://github.com/darkwizard242/vagrant-ubuntu-20.04/archive/master.zip
2. Extracting vagrant-ubuntu-20.04 source code archive: unzip vagrant-ubuntu-20.04.zip -d .
3. Changing to packer build directory: cd vagrant-ubuntu-20.04-master
4. Once customized, run a packer build using: packer build template-branch-others.json

4.2. Initializing your customized version of ubuntu2004 Build:

Once you have built out a ubuntu2004 box. You can easily test it out by adding it as vagrant box using the following commands:

1. vagrant box add myubuntubox /path/to/ubuntu2004.box - This command will add the newly built customized ubuntu2004 box to vagrant so that it can be used. It would be wise to use the exact path to the ubuntu2004 box you have built.

2. vagrant init myubuntubox - This command will initialize the box you have associated your vagrant image with.

3. vagrant up myubuntubox - Boots up the box.
