# 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](https://www.techworld-with-nana.com/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](https://docs.astral.sh/uv/):
```shell
uv sync
```
Configure AWS credentials at `~/.aws/credentials`:
```conf
[default]
aws_access_key_id = AKIA...
aws_secret_access_key = ...
```
And the default region at `~/.aws/config`:
```conf
[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](./add-env-tags.py)
Run:
```sh
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`):
