🎯 Goal

Learn how to containerize a PHP web application using Docker, deploy it to Docker Hub, and share it with others for seamless deployment across different environments.

📋 Prerequisites

Before beginning this exercise, you should:

• Have PHP installed on your local machine (version 7.4 or higher)
• Have Docker Desktop installed and currently running
• Have a Docker Hub account (free at https://hub.docker.com)
• Have basic understanding of command line operations
• Have the PHP application source files ready (either copy from the Appendix at the end of this tutorial or use your own PHP files)

📚 Learning Objectives

By the end of this exercise, you will:

Overview

The objective of this exercise is to create a Virtual Network (vNet) with a default subnet using the Azure Portal, laying the foundation for a secure network architecture. You will also provision three servers having the roles Web Server, Reverse Proxy and Bastion Host respectively. Finally, firewall rules will be created to secure the network using Azure Network Security Groups (NSG)

Step 1: Log in to Azure Portal

1. Open https://portal.azure.com.
2. Sign in with your Azure account credentials.

Step 2: Create a Virtual Network

1. In the Azure Portal, use the search bar at the top to search for “Virtual Networks”.
2. Select Virtual Networks from the search results or from the left menu
3. Click the + Create button at the top of the Virtual Networks page.
4. On the Basics tab, fill in the following information:
   • Subscription: Select your subscription.
   • Resource Group: Choose an existing resource group or create a new one (e.g., DemoRG).
   • Name: Enter DemoVNet.
   • Region: Choose a region close to your location (e.g., North Europe).
5. Click Review + Create and then click Create to deploy the Virtual Network.

Overview

This exercise introduces the Azure Portal, guiding you through the creation of a Virtual Machine (VM). You will configure an Ubuntu Linux VM with a username/password for access and verify that the VM is running successfully by logging into the VM from Azure Cloud Shell.

Step 1: Log in to Azure Portal

1. Open a web browser and navigate to the Azure Portal.
2. Sign in using your Azure account credentials.

Step 2: Create a Resource Group

1. In the Azure Portal, search for “Resource groups” in the search bar.
2. Click “Create” and fill in the following:
   • Subscription: Choose your subscription.
   • Resource Group Name: LabResourceGroup
   • Region: Choose a region (e.g. North Europe).
3. Click Review + Create and then Create.

🎯 Goal

Learn how to provision an Azure Virtual Machine with Docker pre-installed, then deploy containers from Docker Hub including both public images (nginx) and your own containerized applications from the previous exercise.

📋 Prerequisites

Before beginning this exercise, you should:

• Have an Azure subscription with credits available
• Have Azure CLI installed locally (version 2.0 or higher)
• Have completed the previous Docker exercise (PHP application pushed to Docker Hub with multi-architecture support)
• Have basic understanding of Linux command line
• Have SSH client available (built-in on Mac/Linux, use PowerShell on Windows)

⚠️ Note: If you haven’t built your Docker image with multi-architecture support, refer to Step 3 in the previous tutorial for instructions using docker buildx

Overview

The objective of this exercise is to create a Virtual Network (vNet) with a subnet secured by a Network Security Group (NSG) attached to the subnet itself. You will also provision three servers with specific roles: Web Server, Reverse Proxy, and Bastion Host. Application Security Groups (ASGs) will be configured for the Reverse Proxy and Bastion Host, and all server configurations will be automated using cloud-init.

Step 1: Log in to Azure Portal

1. Open https://portal.azure.com.
2. Sign in with your Azure account credentials.

Step 2: Create a Virtual Network

1. In the Azure Portal, use the search bar at the top to search for “Virtual Networks”.
2. Select Virtual Networks from the search results or from the left menu
3. Click the + Create button at the top of the Virtual Networks page.
4. On the Basics tab, fill in the following information:
   • Subscription: Select your subscription.
   • Resource Group: Choose an existing resource group or create a new one (e.g., DemoRG).
   • Name: Enter DemoVNet.
   • Region: Choose a region close to your location (e.g., North Europe).
5. Click Review + Create and then click Create to deploy the Virtual Network.

Step 3: Create Application Security Groups

1. In the Azure Portal, search for Application Security Groups.

Overview

This exercise introduces secure SSH authentication using Azure Portal’s Generate Key Pair feature. You will also connect to the VM using SSH from your local (your laptop) Terminal. While logged in we will explore the Linux filesystem with basic command-line utilities.

Step 1: Log in to Azure Portal

1. Open a web browser and navigate to the Azure Portal.
2. Sign in using your Azure account credentials.

Step 2: Create a Virtual Machine with SSH Key Pair

1. Navigate to Virtual Machines and click Create > Azure Virtual machine.
2. Configure the VM:
   • Subscription: Select your subscription.
   • Create a new Resource Group: LabSSHResourceGroup. (You can create a new resource group here if you don´t have one already)
   • Virtual Machine Name: LabSSHVM.
   • Region: Same as the resource group.
   • Zone options: Select Azure-selected zone
   • Image: Select Ubuntu Server 24.04 LTS.
   • Size: Choose Standard_B1s.
   • Authentication Type: Select SSH Public Key.
   • Username: azureuser.
3. Under SSH Public Key Source, select Generate new key pair.
4. Configure inbound ports:
   • Check Allow selected ports and select HTTP (80) and SSH (22).
5. Note the name for your key pair (e.g., LabSSHKey) and click Download private key and create resource.
