1.7 Setup developing infrastructure

Prerequisites

Warning

You must be running Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11.

Install WSL

Run the command in an administrator PowerShell or Windows Command Prompt and then restart your machine.

# POWERSHELL - WINDOWS
wsl --install

# Some Windows distributions have obsolete packages, you need to specify the distribution name
wsl --install -d Ubuntu

# By default, it will install Ubuntu, to install a different distribution
# To see a list of available Linux distributions available for download through the online store, enter:

wsl --list --online
# or
wsl -l -o.

# To install additional Linux distributions after the initial install, you may also use the command:
wsl --install --distribution <Distribution Name>.

Install GUI

# Install Kali Linux
# POWERSHELL - WINDOWS
wsl --install --distribution kali-linux

# TERMINAL - KALI LINUX
# Update the package list and install the Kali Linux Win-KeX package
sudo apt update
sudo apt install -y kali-win-kex

# Start the Kali Linux GUI
# Inside of Kali WSL
# TERMINAL - KALI LINUX
kex --win -s

# POWERSHELL - WINDOWS
# On Window’s command prompt:
wsl -d kali-linux kex --win -s

Install Docker Desktop

Open Docker Desktop Installer then run the installer.

# POWERSHELL - WINDOWS
# Create a fedora docker container
docker run -it fedora bash

# TERMINAL - FEDORA LINUX
# install utilities on the container (for normal virtual machines we don't need to install them)
dnf install util-linux tree passwd

To find what distribution and version of Linux are you running

# TERMINAL - LINUX
# To find what distribution and version of Linux are you running
cat /etc/os-release

Install VS Code

Install VS Code VS Code To be able to run code directly on the WSL we need the WSL Extension

The Linux command line is a text interface to your computer. Often referred to as the shell, terminal, console, prompt, or various other names,

Setup WSL - Prerequisites

I decided to upgrade my WSL to the latest version Ubuntu 22.04

Prerequisites:

  1. Backup my information (I pushed all the code to git)

  2. Stop and remove the WSL

# POWERSHELL - WINDOWS
wsl --shutdown

wsl --unregister Ubuntu

Setup WSL - Installation

  1. List available Linux distributions

# POWERSHELL - WINDOWS
wsl --list --online
#or
wsl -l -o

  1. Pick your distribution and install it. For this course we will use Ubuntu.

# POWERSHELL - WINDOWS
wsl --install -d Ubuntu

  1. Access the WSL - setup a new user and password

  2. Update all the packages

# TERMINAL - UBUNTU LINUX
sudo apt update && sudo apt upgrade -y

Install packages

# TERMINAL - UBUNTU LINUX
sudo apt install vim python3.10-venv make -y

  1. Disabled password request for my user when running sudo

# TERMINAL - UBUNTU LINUX
sudo su

Update the /etc/sudoers file using vim /etc/sudoers:

# TERMINAL - UBUNTU LINUX
%sudo   ALL=(ALL:ALL) ALL

to

# TERMINAL - UBUNTU LINUX
%sudo   ALL=(ALL:ALL) NOPASSWD:ALL

Save, you need to use wq! don’t forget the !.

  1. Update the ~/.bashrc with aliases for root and your user

# TERMINAL - UBUNTU LINUX
alias ll='ls -ltrha --color=auto' # add arguments to a command that exists
alias ls='ls -ltrha --color=auto' # add arguments to a command that exists
alias vi='vim' # redirect the old application to the new one
alias exot='exit' # correct typing errors
alias clera='clear' # correct typing errors
alias qpositive='history -c && history -w && exit' # link more commands under one

alias bing='git push'
alias bang='git status && git add --all && git commit -m'

alias qqqRunEnv='. venv/bin/activate'
alias eeeCreateVEnv='python3 -m venv venv'
alias rrrInstallRequirements='pip install -r requirements.txt'

alias duck='cd /home/${USER}/sandbox'
export PATH="$PATH:/home/${USER}/sandbox"

after the update of the aliases you need to source them to have them available run source ~/.bashrc

  1. Create your sandbox

# TERMINAL - UBUNTU LINUX
mkdir -p /home/${USER}/sandbox
duck

  1. Create an ssh-key for the machine

# TERMINAL - UBUNTU LINUX
ssh-keygen -t ed25519 -C "${USER}@$(hostname)"

read the newly created key

# TERMINAL - UBUNTU LINUX
cat ~/.ssh/id_ed25519.pub

and add it in the GitHub

  1. Configure git

# TERMINAL - UBUNTU LINUX
git config --global user.email "<MAIL>"
git config --global user.name "<USER>"
git config --global core.editor vim

  1. Clone all your projects

Extending software Installation

  1. Install Terraform

Follow the instructions from HashiCorp

# Ensure that your system is up to date and you have installed the gnupg, software-properties-common, and curl packages installed. You will use these packages to verify HashiCorp's GPG signature and install HashiCorp's Debian package repository.
sudo apt-get update && sudo apt-get install -y gnupg software-properties-common

# Add the HashiCorp GPG key.
wget -O- https://apt.releases.hashicorp.com/gpg | \
gpg --dearmor | \
sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg

# Add the official HashiCorp Linux repository.
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
sudo tee /etc/apt/sources.list.d/hashicorp.list

# Update to add the repository and install Terraform.
sudo apt update && sudo apt-get install terraform

  1. Install Kubectl

# Update the apt package index and install packages needed to use the Kubernetes apt repository:
sudo apt-get update && sudo apt-get install -y ca-certificates curl apt-transport-https
