AWS ECS, AWS CodeDeploy, Terraform, Python API

Complete solution to deploy API build into Docker image to AWS infrastructure created and managed by Terraform.

How it works

1. Developer makes changes to python-api, opens PR, PR get approved and merged.
2. Once PR is merged, Github Action is triggered and new python-api image is pushed into AWS ECR repository.
3. New image in AWS ECR repository triggers AWS CodePipeline, which automaticlly deploys new API version to AWS ECS by using Blue/Green deployment strategy.
4. If automated health checks pass, release is successfull and old API version is removed.

How to use it

Prerequisites

• Clone repository into your own Github reposotory.
• Have AWS account.
• Create AWS user to use AWS CLI.
• Create AWS S3 bucket and AWS DynamoDB table to be used for Terraform State (https://developer.hashicorp.com/terraform/language/settings/backends/s3)
• Put your S3, DynamoDB names and AWS region in ./terraform/backend.tf

Step by step

1. Deploy infra
2. Push pipeline files
3. Push image

Create all needed AWS infrastructure with Terraform:

export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=

3. Run terraform init in order to connect with backend and download plugins (providers).

4. Run terraform workspace new dev in order to create new workspace named dev.

5. Run terraform plan -out=example.tfplan in order to see infrastructure changes that are going to be applied.

6. Run terrafrom apply example.tfplan to apply changes.

7. (optional) If you want to destory infrastructure, run terraform destory -auto-approve.
