Terragrunt

We assumed below folder structure for our terragrunt configuration which will guide the terrform config to be designed in a way we wanted.

Notes:

terragrunt.hcl file drive the execution of terraform source config files.
The name of the terragrunt.hcl file should not be changed in the folder where the terraform source exist. The same file can have different name in the parent folders.
We have environment.hcl file under /dev folder which should carry any environment related variables and inputs.
We have a terragrunt config file at the root of project named root.hcl which need to be explicitly included in the child terragrunt config files. All globale variables and inputs will be manage here.
Run from terragrunt directory terragrunt run-all plan to provision the infrastructure.
Before running terragrunt plan/apply set the aws profile. You can set the profile using the env variable AWS_PROFILE.
Make sure to build and push the container images for the backend, frontend and the collector in order for the application to run in ECS.
- docker buildx build --platform=linux/amd64 --build-arg APP_VERSION=1.0.0 -t <AWS account ID>.dkr.ecr.us-east-1.amazonaws.com/dev-otlp-be-img-repo:latest -f Backend.dockerfile .
- aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin <AWS account ID>.dkr.ecr.us-east-1.amazonaws.com && docker push <AWS account ID>.dkr.ecr.us-east-1.amazonaws.com/dev-otlp-be-img-repo:latest
- Remember to pass the build args correctly, such as APP_VERSION for the backend, and API_URL and OTLP_COLLECTOR_URL to the frontend, so they get replaced in .env.registry
