Spring Boot web app: Sync Elastic Beanstalk with GitHub

Question

I have developed a webapp with Spring Boot and to test it online, I uploaded the WAR on AWS using the Elastic Beanstalk service. But the WAR file is really really big, more than 100 MB, so each time I have to deploy a new version, it takes a lot of time to upload it. Here my question was born...
Is there a way to suynchronize Elastic Beanstalk with my git repo? It would be great to be able to just push the changes on GitHub in order to deploy a new version of the webapp on AWS.

And btw, is it correct that the WAR file is that big?
If it can help, this is the pom.xml file:

Answer 1

You can synchronize your GitHub repository with Elastic Beanstalk by using CodePipeline and CodeBuild.

1. Your pipeline is configured to listen on your repository (on master for example) : source stage.
2. When there is a new commit, your pipeline is triggered.
3. The pipeline uses CodeBuild to build your application to a WAR file : build stage.
4. The last stage of your pipeline deploys your application with Elastic Beanstalk.

Answer 2

What you are describing is continuous deploy or continuous delivery. The AWS tool for this is CodePipeline, and it can use Elastic Beanstalk as a destination .
