Project 9: Deploy a Website to AWS with Ansible

Описание: 📝 Description
💻 Level: Beginner → Intermediate
⏱️ Duration: ~3-4 hours (with live Q&A)

🟢 Goal
Learn how to use Ansible to automate the deployment of a website across multiple AWS EC2 web servers. You will set up an Ansible control server, write an inventory file, configure Ansible, create a playbook that pulls web files from S3 and deploys Apache, and expose the application through an Application Load Balancer and Route 53.

🧱 Session Outline

1️⃣ Architecture Overview
Review the 3-tier VPC architecture and security group configuration for EICE, ALB, Ansible server, and web servers

2️⃣ Key Pair Setup
🔹 Generate SSH key pair on the Ansible server
🔹 Add the public key to GitHub
🔹 Import the public key into AWS Management Console

3️⃣ Launch the Ansible Server
🔹 Launch EC2 instance with Amazon Linux 2023
🔹 Install Ansible via user data script
🔹 Add the private key to the Ansible server

4️⃣ Launch the Web Servers
🔹 Launch EC2 instances with Amazon Linux 2023
🔹 Install Python3 and Boto3 via user data script
🔹 Test SSH connection from Ansible server to web servers

5️⃣ GitHub Repository Setup
🔹 Create a GitHub repository for Ansible playbooks
🔹 Clone the repository on the Ansible server and local machine

6️⃣ Create the Ansible Inventory File
🔹 Add web server private IPs to inventory
🔹 Set ansible_python_interpreter for Amazon Linux 2023
🔹 Ping web servers to test connection

7️⃣ Create the Ansible Config File
🔹 Configure remote_user, inventory, and private_key_file
🔹 Test simplified ping using ansible.cfg

8️⃣ Create the Ansible Playbook
🔹 Configure hosts, become, and vars
🔹 Write tasks to update servers and install Apache
🔹 Download web files from S3 using aws s3 cp
🔹 Unzip, copy, and clean up web files
🔹 Enable and start Apache service
🔹 Run the playbook with ansible-playbook

9️⃣ Application Load Balancer + Route 53
🔹 Create an internet-facing ALB (dev-alb)
🔹 Configure target group and register web servers
🔹 Create a Route 53 A record pointing to the ALB
