Containerfile

####
# This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode
#
# Before building the container image run:
#
# ./mvnw package
#
# Then, build the image with:
#
# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/greeting-service-jvm .
#
# Then run the container using:
#
# docker run -i --rm -p 8080:8080 quarkus/greeting-service-jvm
#
# If you want to include the debug port into your docker image
# you will have to expose the debug port (default 5005) like this :  EXPOSE 8080 5005
#
# Then run the container using :
#
# docker run -i --rm -p 8080:8080 -p 5005:5005 -e JAVA_ENABLE_DEBUG="true" quarkus/greeting-service-jvm

## Configure the JAVA_OPTIONS, you can add -XshowSettings:vm to also display the heap size.

## We make four distinct layers so if there are application changes the library layers can be re-used
