In this article we'll focus on how to dockerize a Spring Boot Application to run it in an isolated environment, a.k.a.

Then we show a couple of options that use build plugins (for Maven and Gradle) instead of docker. You can clone or download the entire github repository and import this project as a maven project into eclipse.

To configure our Docker image to run our Spring Boot application, we will want to:
