thomasni91 / hello-world-terraform

A terraform project to deploy a simple nodejs based hello-world app.

Pre-requisite

• Install terraform v1.0.0
• Setup the aws cli credentials with default profile name.

Setup

1. Apply the remote_state terraform project. This will create s3 bucket and lock table for keeping remote state for other tf projects.

cd infra/accounts/dev/remote_state; terraform apply

2. Apply the ecs terraform project.

cd infra/accounts/dev/ecs; terraform apply

This will output

• URL to access the web server.
• ECR repo url where docker images should be pushed.

Development

1. Make desired code changes to src directory.
2. Run docker build

cd src; docker build -t <docker_ecr_repo_url>:<version> .

3. Docker login into the ECR repo

aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <ecr_repo_url>

4. Publish docker image

docker push <docker_ecr_repo_url>:<version>

5. Apply the ecs terraform project with the version provided in above step

cd infra/accounts/dev/ecs; terraform apply -var="release_version=<release_version>"

TODO

• Use terragrunt for making terraform code DRY in case new env is added.
