Hands-on exercise 1 – provisioning resources for Chapter 8’s exercises

To follow along with the exercises in this chapter and the next one, we will provision some Azure resources to work with. We have prepared an Azure ARM template in the GitHub repository for this book for this purpose. The template will deploy an Azure virtual network with three subnets. The public subnet will have an Ubuntu Linux VM with NGINX installed as shown in Figure 8.5. The VM has a public IP, and it is reachable directly from the internet. The other two subnets are empty. Here are the tasks that we will complete in this exercise:

  • Task 1: Initialize template deployment in GitHub
  • Task 2: Complete the parameters and deploy the template to Azure
Figure 8.5 – Chapter 8 exercises scenario

Let us begin deploying our template deployment:
