Deploying a Static Website on AWS S3 & EC2 Using Terraform
Infrastructure as Code (IaC) simplifies cloud management. In this guide, we'll automate the deployment of a static website on AWS S3 and create an EC2 instance using Terraform.
What We'll Cover
- S3 Bucket Creation & Hosting – Automating website deployment.
- Bucket Policy for Public Access – Ensuring public accessibility.
- EC2 Instance Creation – Managing compute resources.
- Using Variables & Outputs – Making the configuration reusable.
Prerequisites
- AWS account with CLI configured (
aws configure) - Terraform installed (
terraform -v)
Step 1: Configure Terraform & AWS Provider
Create a main.tf file and define the Terraform and AWS provider configuration:
terraform {
required_version = ">= 1.7.4"
required_providers {
aws = {
source = "hashicorp/aws"
version = "5.40.0"
}
}
}
provider "aws" {
profile = "default"
region = "us-east-1"
}
Step 2: Create an S3 Bucket for Static Website Hosting
resource "aws_s3_bucket" "website_bucket" {
bucket = "my-static-website-43234"
}
resource "aws_s3_bucket_website_configuration" "website_config" {
bucket = aws_s3_bucket.website_bucket.id
index_document {
suffix = "index.html"
}
}
resource "aws_s3_object" "index_file" {
bucket = aws_s3_bucket.website_bucket.id
key = "index.html"
source = "index.html"
content_type = "text/html"
etag = filemd5("index.html")
}
Step 3: Configure Public Access Policy
resource "aws_s3_bucket_public_access_block" "public_access" {
bucket = aws_s3_bucket.website_bucket.id
block_public_acls = false
block_public_policy = false
}
resource "aws_s3_bucket_policy" "allow_public_access" {
bucket = aws_s3_bucket.website_bucket.id
policy = jsonencode({
Version = "2012-10-17"
Statement = [
{
Sid = "PublicReadGetObject"
Effect = "Allow"
Principal = "*"
Action = "s3:GetObject"
Resource = "${aws_s3_bucket.website_bucket.arn}/*"
}
]
})
depends_on = [aws_s3_bucket_public_access_block.public_access]
}
Step 4: Create an EC2 Instance
resource "aws_instance" "web_server" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
tags = {
Name = "WebServerInstance"
}
}
Step 5: Use Variables & Outputs
Define variables in variables.tf:
variable "instance_type" {
description = "Type of EC2 instance"
type = string
default = "t2.micro"
}
variable "website_bucket_name" {
description = "S3 bucket name for website hosting"
type = string
default = "my-static-website-43234"
}
Define outputs in outputs.tf:
output "website_url" {
value = "http://${aws_s3_bucket.website_bucket.bucket}.s3-website.${provider.aws.region}.amazonaws.com"
}
output "ec2_instance_id" {
value = aws_instance.web_server.id
}
output "ec2_public_ip" {
value = aws_instance.web_server.public_ip
}
Step 6: Deploy with Terraform
terraform init
terraform plan
terraform apply -auto-approve
To destroy the infrastructure:
terraform destroy -auto-approve
Conclusion
By following these steps, you automated the deployment of an S3-hosted static website and an EC2 instance using Terraform. This approach ensures reproducibility, scalability, and efficient cloud management. 🚀
