Dockerfile

####
# 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  -t helpdev/app-quarkus-jvm .
#
# Then run the container using:
#
# docker run -i --rm -p 8080:8080 helpdev/app-quarkus-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 5050
#
# Then run the container using :
#
# docker run -i --rm -p 8080:8080 -p 5005:5005 -e JAVA_ENABLE_DEBUG="true" helpdev/app-quarkus-jvm
#
# Sample to run Flyway migration :
#
# docker run --rm --workdir="/flyway" --entrypoint /flyway/flyway helpdev/app-quarkus-jvm -url=jdbc:mysql://172.17.0.1:3306 -schemas=app -user=root -password=test123 -connectRetries=60 migrate
