This guide outlines the steps to deploy a simple Todo List application to AWS Elastic Beanstalk using Terraform and Docker.

• Dockerfile: Defines the configuration for building the Docker image.
• Dockerrun.aws.json: Specifies the Docker container configuration for Elastic Beanstalk.
• provider.tf: Terraform configuration file for provider configuration.
• iam.tf: Terraform configuration file containing iam roles and policy definitions.
• ecr.tf: Terraform configuration file for containing elastic container registry to storing the docker images as well as automated resource for pushing docker image to the ecr.
• main.tf: Terraform configuration file for creating AWS resources(elastic beanstalk and other related resources).
• output.tf: Terraform output file for defining the outputs of the deployment.
• /todo-list: Directory containing the source code for the todo list application. origanlly pulled from https://github.com/bradtraversy/50projects50days/tree/master/todo-list

• Add new tasks
• Mark tasks as completed
• Delete tasks

Before deploying the application, ensure you have the following prerequisites installed:

• Terraform
• Docker
• AWS CLI configured with appropriate credentials

1. Clone the Repository:

2. updating dokcerrun.aws.json with your credentials Open the Dockerrun.aws.json file in your project directory and update the <Name> fields with your AWS account ID, region, repository name, and version. The format should be:

   "Name": "<ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com/<NAME>:<VERSION>"

3. Deploy Infrastructure with Terraform:

   Initialize Terraform and apply the configuration to deploy the Todo List application on AWS Elastic Beanstalk.

   terraform init
   terraform apply --auto-approve

4. Access the Application:

   Once the deployment is complete, you can access the Todo List application in your browser using the outputed URL from the terminal .

If you want to tear down the infrastructure, you can destroy it using Terraform:

```bash
terraform destroy --auto-approve
``` 

A S3 bucket will be created by the elastic beanstalk by the name "elasticbeanstalk--" which is not automatically deleted to prevent accidental deletion of the bucket as it contain important config for the elastic beanstalk to delete that refer to https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.S3.html

Also remove the docker images from your local system

```bash
docker images //to view the current running images
docker rmi <image-id>
```
