Coursework: Infrastructure as Code for CYF Hotel

Infrastructure as Code for CYF Hotel Frontend in S3

  1. Objective: Use Terraform to deploy your CYF Hotel frontend to an S3 bucket.
  2. Steps:
    • Write a Terraform configuration file (main.tf) to define the S3 bucket.
    • Include the necessary configurations like ACL, policy, and versioning.
    • Deploy the code to AWS.
  3. Outcome: After running terraform apply, you should see the CYF Hotel frontend live on the S3 bucket URL.

Infrastructure as Code for CYF Hotel Backend in EC2

  1. Objective: Use Terraform to deploy your CYF Hotel backend to an EC2 instance.
  2. Steps:
    • Write a Terraform configuration file (main.tf) to define the EC2 instance.
    • Include configurations for security groups, key pairs, and IAM roles if necessary.
    • Deploy the code to AWS.
  3. Outcome: After running terraform apply, the backend should be running on an AWS EC2 instance accessible via its IP address.

Infrastructure as Code for CYF Hotel Database in RDS

  1. Objective: Use Terraform to deploy your CYF Hotel database to an RDS instance.
  2. Steps:
    • Write a Terraform configuration file (main.tf) for the RDS database.
    • Include necessary configurations like database engine, version, and credentials.
    • Deploy the code to AWS.
  3. Outcome: After running terraform apply, the database should be live and reachable on the RDS instance.

Extra Exercise: Using Terraform Modules and Remote State

Objective

In this exercise, you will utilize a Terraform module to create a reusable configuration for S3 buckets. Additionally, you’ll implement remote state management using an S3 bucket.

Steps

  1. Create a Terraform Module for S3 Buckets

    • Create a new directory named s3_module and place a new Terraform file inside it, e.g., main.tf.
    • Define the Terraform code for an S3 bucket inside this file.

  2. Implement Remote State in S3

    • In your main Terraform configuration (main.tf), configure the backend for remote state using S3.

  3. Initialize and Apply

    • Initialize your Terraform project.
    • Apply the configuration to create the S3 bucket using the module and configure remote state.

Validation

  • Confirm that the S3 bucket was created as expected.
  • Check the S3 bucket where you store the remote state to ensure that the terraform.tfstate file is present.
