this is putting the result at /jrootfs in the final image. We need to adjust it somehow so it unpacks over / instead.

COPY deployments /
COPY customJVM ${JAVA_HOME}
COPY runScripts /opt/jboss/container/
# these are in the micro image
RUN rm -rf /var/lib/dnf /var/lib/rpm

ENV JAVA_HOME="${JAVA_HOME}" PATH="${JAVA_HOME}/bin:$PATH"
