Module 14 - Automation with Python

This repository contains a demo project created as part of my DevOps studies in the TechWorld with Nana – DevOps Bootcamp.

Demo Project: Automate configuring EC2 Server Instances

Technologies used: Python, Boto3, AWS

Project Description:

• Write a Python script that automates adding environment tags to all EC2 Server instances

---

Prerequisites

Install Python dependencies with uv:

uv sync

Configure AWS credentials at ~/.aws/credentials:

[default]
aws_access_key_id = AKIA...
aws_secret_access_key = ...

And the default region at ~/.aws/config:

[default]
region = us-east-1

---

Create EC2 instances manually

Navigate to AWS Dashboard → EC2 → Launch instances.

1. Launch 2 instances in Frankfurt

• Region: Europe (Frankfurt) — eu-central-1
• Number of instances: 2
• Leave all other settings at their defaults.

2. Launch 1 instance in Paris

• Region: Europe (Paris) — eu-west-3
• Number of instances: 1
• Leave all other settings at their defaults.

---

Execute the Python script

The script tags Frankfurt instances as environment=prod and Paris instances as environment=dev.

Source: add-env-tags.py

Run:

python3 ./add-env-tags.py

A successful run produces no output.

Verify the tags in the EC2 dashboard

For each instance, open Instance → Tags and confirm the environment tag is set.

Frankfurt (environment=prod):

Paris (environment=dev):

Clean up created instances
