Deploy Dockered Gradled Spring Boot Application to Elastic Beanstalk

Source code

After download, change /build/docker/Dockerfile first line to FROM frolvlad/alpine-java

Preparation

Java 8
Docker downloaded and started
AWS Cli version 2

Build

./gradlew clean build

Build Docker

./gradlew clean buildDocker

Run

java -jar build/libs/spring-boot-docker-beanstalk.jar

Run Docker

Run the spring boot app locally

docker run -p 8080:8080 -t springboot-docker-beanstalk

Tag the Docker image

Tag the docker image and point at remote registry
docker tag springboot-docker-beanstalk <accountid>.dkr.ecr.<your-default-region>.amazonaws.com/springboot-docker-beanstalk

Docker Login to AWS ECR

Give docker permissions to access AWS ECR

AWS Cli Version 2:aws ecr get-login-password

Run the output from the previous command
docker login -u AWS -p <password> https://<accountid>.dkr.ecr.<your-default-region>.amazonaws.com

Create Repository

Create the repository in the ECR for our application.

aws ecr create-repository --repository-name springboot-docker-beanstalk

Push to AWS ECR

Push the docker image to ECR.

docker push <accountid>.dkr.ecr.<your-default-region>.amazonaws.com/springboot-docker-beanstalk:latest

Ensure your image is in the repository.

aws ecr describe-images --registry-id <registry-id (same as aws accountid)> --repository-name springboot-docker-beanstalk

Give permission

The above deployment failed because ECR permission is not given to eb role.

In AWS -> IAM -> Roles - > pick the role your beanstalk is using.

In my case it was set to aws-elasticbeanstalk-ec2-role

Under Permissions for the role, attach policy: AmazonEC2ContainerRegistryReadOnly

Deploy again: eb deploy

eb open or go http://YourAppName.YourDefaultRegion.elasticbeanstalk.com/
