AWS ECS & CloudMap Prometheus Discovery - Example

Note: This example is NOT 100% production-ready. It is meant to show case where this application really fits into your AWS environment.

This is a complete example of what it takes to run an observable infrastructure in AWS ECS.

This example uses Terraform to provision the infrastructure, so some familiarity with Terraform is necessary, but not strongly required.

~/environments/* - this is where you would store your environment configurations. In this example I have a single configuration for dev.

~/modules/* - repeatable infrastructure constructs that can be used across multiple environments:

infrastructure - this module creates shared resources in which your applications are run. This should typically be declared once per environment.
application - this is the ECS application module that will create the ECS service, task definition. You can have as many applications as you want.
monitoring - this module creates the monitoring resources for your applications.

This example assumes you to already have a VPC with public and private subnets defined.

Install Terraform so it is available in your PATH.

Reload/restart of your shell may be required.
Navigate to the ~/examples/environments/dev directory.
Paste AWS credentials in your shell for the target environment
Run terraform init
Adjust application to your needs.
Run terraform plan -out plan.tfplan
Inspect the plan and confirm it looks good
Run terraform apply plan.tfplan to apply the changes

When you're done, remember to clean up:
