amazon-ecs-cli | The Amazon ECS CLI enables users to run their applications on ECS/Fargate using the Docker Compose f | AWS library

I use an open-source server application running on Docker Compose. It has a few services, including PostgreSQL DB and Redis.

How can I best deploy this application to AWS in full IaC with Terraform?

ecs-cli now supports sending docker compose configs in Amazon ECS.

However, I do not think it could be integrated with the Terraform workflow (which is maybe not a big fuss). What I know for sure is that ecs-cli is not supported in CloudFormation, as per this issue, still open at this time. So I assume it cannot easily be added to Terraform either.

• Take your docker-compose.yml file, translate it to kubectl YAML.
• (Prepare to doing so every time the package upgrades).
• Deploy using Terraform's + EKS APIs (minimal example).

But that is not fully IaC yet. And you have to retranslate your config each time the docker-compose changes in the source repository. And it sounds like a lot of work.

• Write a Helm chart for the application.
• Run Terraform to start a cluster.
• Still run Terraform with a helm provider to install the application with Helm on the cluster.

I read Kompose can automagically translate a Docker Compose configuration to a k8s configuration, but they don't appear to be ported on AWS, not to talk about Terraform.

• Build a custom EC2 AMI with Packer.
• Using Terraform, set up the DB, Redis and all permissions / network / etc.
• Start an EC2 instance with the custom AMI.
• The AMI contains (customized) application code, especially the docker-compose.yml. And the Docker images.
• The AMI starts a Docker Compose systemctl service.

That would kind of hurt: long builds, difficult monitoring, no scaling.

• I mentioned I need full IaC. What I mean by it is:
  1. The written config (and it only) on master tells you what is deployed.
  2. The deploy will complete without my team having to run any other command. It basically works either on CI/CD or on single-push'n'go.
  3. Monitoring and alerting are easily configured in the IaC.
• I wish to replace some services with AWS components (namely, the PostgreSQL service by an RDS, and the Redis service with an ElastiCache).
• The application happens to be Apache Superset. However I am also wondering what is considered the best general approach to this Docker Compose problem.
