Learning Terraform and Docker with AWS provider

This repository builds and deploys a simple application using Terraform to deploy the infrastructure, Docker to build the image, and AWS Elastic Beanstalk to run the container.

Applied Concepts

• Elastic Bean Stalk (ECS) to run containers.
• Elastic Container Registry (ECR), repository to store docker images.
• Terraform Backends, to save states in the cloud.
• AWS Permissions with role, policies and profile.
• AWS S3 Bucket to store terraform states and others files.

Useful resources

• Official Terraform Docs
• Official AWS Docs
• ECR Public Repository

Explored

• How to create Docker images for a Django project.

• AWS Role, Policy and Profile with Terraform to assign permissions to BeanStalk to manage containers.

• Run applications with Elastic Beanstalk through Terraform:

  • application
  • environment
  • versions

• Deploy the application version into Elastic Beanstalk.

• Put docker image on Elastic Beanstalk Repository (ECR).

• Create Dockerrun.aws.json to run a Beanstalk application.

• Create, configure and add files to a AWS S3 Bucket through the Terraform.

Deploy

---

Infra

1. Go to

   cd ./env/prod
   

2. Check

   terraform plan
   

3. Deploy

   terraform apply
   

Web Interface:

http://<elasticbeanstalk_dns>:80

Update application version

1. Build new image

   cd ./api
   docker build -t [AWS_ACCOUNT_ID].dkr.ecr.[REGION].amazonaws.com/production:v1 .

2. Push image to ECR

    docker push [AWS_ACCOUNT_ID].dkr.ecr.[REGION].amazonaws.com/production:v1
   
   aws ecr get-login-password --region [REGION] | docker login --username AWS --password-stdin [AWS_ACCOUNT_ID].dkr.ecr.[REGION].amazonaws.com

3. ZIP Dockerfilerun.aws.json

   zip -r production.zip Dockerrun.aws.json

4. Deploy with Terraform

   terraform init
   terraform apply

5. Update application version

   aws elasticbeanstalk update-environment --environment production-environment --version-label production
