Build a Spring Boot application with Docker

cd java-in-container-dev/spring-doge-workspace/spring-doge/

Look the Dockerfile for multi stage build. This is the file that would be used in a CI/CD pipeline.

docker build -t chanezon/spring-doge .

Or look at Makefile and Dockerfile.dev for manual build using a container: that way the maven cache is reused from one build to the other. You'd use that in development.

make jar
make image

Debug a Spring Boot application in a containerized IDE

see X11 Setup

cd java-in-container-dev/spring-doge-workspace/spring-doge/
startx
docker-compose -f docker-compose.ide.yml up

start debugging in STS.
