Provisioning AWS with S3 Bucket DynamoDB as Backend Using Terraform Ad-Hoc Script

Intro

Why was this repository created? Well, using S3 as a Backend is somewhat tricky. You need to provide resources (such as S3 Buckets) first, before adding the S3 block backend "s3" {} block. It is not good practice to manually create S2 Buckets since the AWS provision's life cycle should rely on Terraform State File. You will occasionally encounter errors when you do that. Like what you can see below:

Error: Error inspecting states in the "local" backend:
S3 bucket does not exist.

So what's this setup.sh can do is to create S3 Buckets and dynamoDB resources first and run the terraform provision again with the "S3" backend. Specifically, this repo solves the following:

• Avoiding S3 Bucket Common Errors
• Avoiding conflicts on deployments among developers using Terraform State Locking
• AWS profile and credentials checks

Getting Started

Before you get started, you need to have the following:

Requirements

• Terraform CLI
• Git Bash
• AWS IAM account with AdministratorAccess priviledge
• AWS Local Authentication aws configure

Cloning

I prefer not to talk about it here, so go over to their official Terraform Install documentation

When you're in your favorite CLI terminal, type in

git clone https://github.com/esstat17/Terraform-S3-Backend-AWS-VPC-DynamoDB-Template.git

.. and you're good to go

Executing program

• After you've downloaded this archive, navigate to the project folder using your CLI or Terminal command tool.

Change Directory to project folder and run the script

• Initializing the script, installing package dependencies, terraform plan and deployments

cd Terraform-S3-Backend-AWS-VPC-DynamoDB-Template/

To run the script

./setup.sh your-app-name

To undo all provisions

• Undo all commands above or revert them to the 0 state.

git checkout HEAD -- backend.tf && terraform init -migrate-state -force-copy && terraform destroy -auto-approve && echo "# edited" >> ./backend.tf
