What is Terraform?

HashiCorp Terraform is an infrastructure as code (IaC) tool that lets you define both cloud and on-prem resources in human-readable configuration files that you can version, reuse, and share.

Let’s get started!

Objectives:

1. Sign in to AWS Management Console

2. Create the following organizational structure

3. Create files - index.html and error.html

4. Under s3_files directory: Create 4 files - variables.tf, terraform.tfvars, main.tf, outputs.tf

5. Initialize Terraform

6. To generate the action plans

7. Create all the resources declared in main.tf configuration file

8. Validate all resources created

9. Test the S3 Static web site on the new web browser

Pre-requisites:

AWS user account with admin access, not a root account.
Cloud9 IDE with AWS CLI.

Resources Used:

Terraform documentation for AMI.

Tutorial: Configuring a static website on Amazon S3.

Steps for implementation to this project:

1. Sign in to AWS Management Console

Make sure you're in the N. Virginia (us-east-1) region

2. Let’s create the following organizational structure as shown below:

3. Create files - index.html and error.html

Under s3_files directory, create a html folder, and then create error.html and index.html files in it.
index.html

4. Under `s3_files` directory:

Create 4 files - variables.tf, terraform.tfvars, main.tf, outputs.tf
1. variables.tf - to declare all the global variables with a short description and a default value.



# required for AWS
variable "access_key" {
    description = "Access key to AWS console"
}
variable "secret_key" {
    description = "Secret key to AWS console"
}
variable "region" {
    description = "Region of AWS VPC"
}

2. terraform.tfvars - Replace the values of access_key and secret_key by copying your AWS Access Key ID and Secret Access Key ID.



region = "us-east-1"                
access_key = "<YOUR AWS CONSOLE ACCESS ID>"             
secret_key = "<YOUR AWS CONSOLE SECRET KEY>"

3. main.tf - Creating a S3 bucket and its components



provider "aws" {
  region     = var.region
  access_key = var.access_key
  secret_key = var.secret_key
}

##### Creating a Random String #####
resource "random_string" "random" {
  length = 6
  special = false
  upper = false
} 

##### Creating an S3 Bucket #####
resource "aws_s3_bucket" "bucket" {
  bucket = "revbucket-${random_string.random.result}"
  force_destroy = true
}

resource "aws_s3_bucket_website_configuration" "blog" {
  bucket = aws_s3_bucket.bucket.id
  index_document {
    suffix = "index.html"
  }
  error_document {
    key = "error.html"
  }
}

resource "aws_s3_bucket_public_access_block" "public_access_block" {
  bucket = aws_s3_bucket.bucket.id
  block_public_acls       = false
  block_public_policy     = false
  ignore_public_acls      = false
  restrict_public_buckets = false
}

##### will upload all the files present under HTML folder to the S3 bucket #####
resource "aws_s3_object" "upload_object" {
  for_each      = fileset("html/", "*")
  bucket        = aws_s3_bucket.bucket.id
  key           = each.value
  source        = "html/${each.value}"
  etag          = filemd5("html/${each.value}")
  content_type  = "text/html"
}

Apply Bucket Policy
in S3, click the Permissions tab
replace with your S3 bucket ARN
Note: Ensure the trailing /* is present so the policy applies to all objects within the bucket.



{
    "Version": "2012-10-17",
    "Id": "Policy1234567890123",
    "Statement": [
        {
            "Sid": "Stmt1234567890123",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::arn:aws:s3:::revbucket-npau9q/*"
        }
    ]
}

Click Save changes

4. outputs.tf - displays the output as website endpoint.



output "s3_bucket_id" {

  value = aws_s3_bucket_website_configuration.blog.website_endpoint

}

Initialize Terraform

terraform version

terraform init will check for all the plugin dependencies and download them if required, this will be used for creating a deployment plan.
Run terraform init

6. To generate the action plans, run the below command:

Run terraform plan

7. Create all the resources declared in main.tf configuration file, run the below command:

Run terraform apply
Wait for 4-5 minutes to create all the resources.

8. Validate all resources created

s3 bucket

index.html, error.html

9. Test the S3 Static web site on the new web browser

Go to the properties tab of S3 bucket and scroll to the end of this page to find Static website hosting options.
Copy the Bucket website endpoint and paste into the new tab of your web browser, with /index.html at the end.

test error.html feature is working or not, replace index.html with rev.html.
Now you should see the contents of error.html

Cleanup

Run terraform destroy
Delete Cloud9 environment

What we have done so far

Using Terraform, We created a static site using an AWS S3 bucket with the pre-created HTML files for your static web site.
