Simple EC2 backed ECS deployment

This module deploys a simple EC2 backed ECS HTTP webapp, with a docker image built from the source folder.

Notes:

• The default vpc is used, as there is no need for private subnets in this simple example.
• This module is compatible with AWS "free tier".
• This module has been tested on WSL2 and Windows.
• The docker image is automatically built and pushed to ECR if the /project folder changes, but the service must be updated via the console.

Requirements:

• Terraform
• AWS CLI
• Docker

Instructions:

• Run AWS configure with with your key/secret. Define your desired region in the providers.tf file.
• In the top level main.tf, define your module (see ecs_ec2 vars file and examples for input). There is an example node.js app deployment available to be uncommented.
• Run terraform init, followed by terraform apply at the tf-simple/ folder level (where the modules are instantiated), type yes to confirm if you are happy with the resources being created.
• Once successfully applied, run terraform state show 'module.<my-module-name>.aws_lb.lb' to find the dns_name of the load balancer. Alternatively, you can find the dns_name by going to the EC2 service console, and clicking on the "load balancers" section.
• Your app should be available at this DNS address.
• Remember to run terraform destroy when finished to avoid incurring costs!
