#Lab: Infrastructure with Pulumi

Write infrastructure as code using real programming languages.

#🎯 Objectives

Install and configure Pulumi
Create infrastructure with TypeScript
Compare with Terraform approach

#📋 Prerequisites

Node.js 18+ installed
AWS credentials configured

#⏱️ Duration: 30 minutes

#Task 1: Install Pulumi (5 min)

bash

1# Install Pulumi CLI
2curl -fsSL https://get.pulumi.com | sh
3
4# Verify installation
5pulumi version
6
7# Login (local state for learning)
8pulumi login --local

#Task 2: Create New Project (5 min)

diagram

mkdir ~/pulumi-lab && cd ~/pulumi-lab

# Create new project
pulumi new aws-typescript --name my-infra --yes

# Project structure:
# ├── Pulumi.yaml      # Project config
# ├── Pulumi.dev.yaml  # Stack config
# ├── index.ts         # Infrastructure code
# ├── package.json     # Dependencies
# └── tsconfig.json    # TypeScript config

#Task 3: Write Infrastructure (10 min)

#Pulumi vs Terraform Comparison

Feature	Pulumi	Terraform
Language	TypeScript, Python, Go, etc.	HCL
Type Safety	Yes	No
IDE Support	Full	Limited
Testing	Native unit tests	Limited
State	Pulumi Cloud or S3	Terraform Cloud or S3

#✅ Success Criteria

Pulumi installed and configured
Project created with TypeScript
pulumi preview shows resources
Infrastructure deployed (optional)

#🧹 Cleanup

bash

pulumi destroy -y
cd ~ && rm -rf pulumi-lab
