How to Build, Push, and Deploy a Dockerized Application to AWS Elastic Beanstalk Using ECR

Back

Follow these steps to efficiently build, push, and deploy a Dockerized application to AWS Elastic Beanstalk using Amazon Elastic Container Registry (ECR):

1. Build the Docker Image

Use Docker Compose to build the application image locally:

bash
docker compose up --build

  • This command creates or rebuilds services defined in the docker-compose.yml file, ensuring all dependencies are built and updated.

2. Authenticate Docker to AWS ECR

Before pushing the Docker image, authenticate Docker to the target ECR registry:

bash
aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin 985542660797.dkr.ecr.us-east-1.amazonaws.com

  • Replace us-east-1 with your AWS region as needed.
  • Replace the account ID and registry URL if using a different AWS account or repository.
  • This command securely logs Docker into the AWS ECR registry.

3. Push the Docker Image to ECR

Push the built Docker image to the ECR repository:

bash
docker push 985542660797.dkr.ecr.us-east-1.amazonaws.com/edgarallan/wesapi-staging

  • Ensure the image tag matches what was built in the previous steps.
  • This makes the image available for deployment in AWS services.

4. Deploy to AWS Elastic Beanstalk

Deploy the latest image to an AWS Elastic Beanstalk environment:

bash
eb deploy

  • The eb deploy command uploads the current application version (configurations and Docker image) to the Elastic Beanstalk environment.
  • Ensure the Elastic Beanstalk CLI is set up and configured for the correct environment.

Best Practices

  • Always verify AWS credentials and permissions before starting the deployment process.
  • Use version tags for Docker images to avoid confusion and ensure deployment consistency.
  • Monitor the deployment status in the AWS Elastic Beanstalk console for confirmation and troubleshooting.
