Terraform-S3-Static-Website

Objective

This tells you how to provision a static website on AWS S3 using Terraform

Prerequisites

How to configure

To begin with, we need an S3 bucket defined in our terraform project. The code block includes website block that sets up web hosting for the bucket. You need to enter the region, aws access key and secret key in the provider.tf file, bucket name and website file location in the s3.tf file.

resource "null_resource" "remove_and_upload_to_s3" {
  provisioner "local-exec" {
    command = "aws s3 sync ${path.module}/website s3://${aws_s3_bucket.bucket.id}"
  }
}
resource "aws_s3_bucket" "bucket" {
  bucket = "s3web.devopsstudy.tech"
  acl    = "public-read"
  policy = file("policy.json")

   website {
    index_document = "index.html"
    error_document = "error.html"
}

  tags = {
    Name        = "s3web.devopsstudy.tech"
  }

output "site-url" {
    value = aws_s3_bucket.bucket.website_endpoint
}

A bucket policy with necessary previlege is attached to the bucket to grant access permissions.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
	           "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::s3web.devopsstudy.tech/*"
        }
    ]
}

Usage

Clone the repository

$ git clone https://github.com/Swathikarun/terraform-s3-staticwebsite.git

$ cd terraform-s3-staticwebsite

$ terraform init

$ terraform apply

Also you can invoke awscli commands using null_resource provisioner to upload the contents in a folder, as suggested here.

resource "null_resource" "remove_and_upload_to_s3" {
  provisioner "local-exec" {
    command = "aws s3 sync ${path.module}/s3Contents s3://${aws_s3_bucket.site.id}"
  }
}
