🛠 Installation

This instruction can be used for all environments with Development (Dev) environment as an example.

1. Install Terraform, AWS CLI, Docker to your machine.

2. Create AWS account and bind credit card.

3. Prepare a domain.

4. Create IAM user with AdministratorAccess policy and save AWS credentials to local machine with aws-terrajet-dev profile name

5. Set up environment variables in envs/dev.tf

6. Create 2 ssh keys for ECS and EC2 bastion

   ssh-keygen -t ed25519 -f ~/.ssh/terrajet_dev_ecs
   ssh-keygen -t ed25519 -f ~/.ssh/terrajet_dev_bastion
   

7. Clone template.secrets.env.yaml secret template in /secrets folder with name secrets.dev.yaml

8. Update RDS username, password and public key of 2 ssh keys created above to secrets.dev.yaml

9. Run terraform init

10. Run terraform apply, then type 'yes'

11. Update information of created services in Output section to domain provider and deploy section.

    api_domain = "<your-domain>"
    bastion_dns = "<url>"
    db_endpoint = "<url>"
    ecr_repository_urls = {
    "api" = "<url>"
    }
    route_53_ns = tolist([
    "<ns>",
    "<ns>",
    "<ns>",
    "<ns>",
    ])
    s3_web_app_bucket_name = "terrajet-dev-static-web-app"
    

    1. Update Route53 NS to your domain provider.
    2. Go to /apps folder and update deploy.sh file with above values.

12. Go to /apps folder and run deploy.sh to deploy API and web app

13. Access your 'domain' and 'api.domain' URL to check the app is running.

🧹 Cleanup

1. Run terraform destroy, then type 'yes'
2. Delete your AWS account.

📌 Extra step for Production

• Move your Terraform state to safe backend like S3 or Terraform Cloud

❔ FAQ

Q: Why ECS is used for monolith app?

Deploying an app on AWS using EC2 is a commonly used and straightforward approach. However, it can be challenging to maintain and scale, particularly when working with Docker containers. On the other hand, ECS cluster may appear more complex at first glance, but it actually simplifies the process. With ECS, you leave all the container control tasks for it, allowing you to focus on your code.

Q: Why is ECS but not Kubernetes?

Although Kubernetes is popular and strongest for container clusters, but it's not necessary for our regular workload. It's resource-intensive and better suited for large-scale projects with a dedicated DevOps team. ECS is simpler and suitable for small to medium-sized monolithic apps.
