Deploying a Dockerized Spring Boot application to AWS Elastic Beanstalk.

Getting started

2. Configure the AWS Elastic Beanstalk CLI:

   WARNING: You will be charged for these resources until they are destroyed.

4. Visit the outputted environment CNAME, e.g. http://aws-eb-demo-dev.eu-west-2.elasticbeanstalk.com/

Manual deployment

To manually deploy the project to AWS:

mvn clean package
docker build -t markhobson/aws-eb-demo .
docker login
docker push markhobson/aws-eb-demo
eb deploy

Continuous deployment

We'll use CircleCI for continuous deployment.

1. Add the project

2. Add environment variables for your Docker Hub credentials:

   • DOCKER_REGISTRY_USERNAME
   • DOCKER_REGISTRY_PASSWORD

3. Add environment variables for your AWS credentials and region:

   • AWS_ACCESS_KEY_ID
   • AWS_SECRET_ACCESS_KEY
   • AWS_DEFAULT_REGION

The job builds the project within the Docker container .circleci/images/primary/Dockerfile. If you need to rebuild this:

docker build -t markhobson/aws-eb-demo-primary .circleci/images/primary
docker login
docker push markhobson/aws-eb-demo-primary

Destroying

To terminate the environment in AWS:

eb terminate --force aws-eb-demo-dev

You will no longer be charged for these resources.
