Installing the command-line tools to configure Azure services

In this recipe, we will get the Azure CLI tool called az and kubectl installed. 

Let's perform the following steps:

1. Install the necessary dependencies:

$ sudo apt-get update && sudo apt-get install -y libssl-dev \
libffi-dev python-dev build-essential

2. Download and install the az CLI tool: 

$ curl -L https://aka.ms/InstallAzureCli | bash

3. Verify the az version you're using:

$ az --version

4. Install kubectl, if you haven't installed it already:

$ az aks install-cli

If all commands were successful, you can start provisioning your AKS cluster.
