Updated: Now the code uses Spring Boot 2 and Java 10.
This project shows you how to dockerize a Spring Boot application using a single Dockerfile or combining it with docker-compose.
The guide to build the code and understand the different alternatives is located at https://thepracticaldeveloper.com/2017/12/11/dockerize-spring-boot/.
Make sure you generate first the .jar file by running:
mvn clean package
Then, you just need to execute:
docker-compose up
Note that there are two Dockerfiles in this repository. The Dockerfile-build not only runs the app in the container but also builds it using Maven. Check out the post for more details.
