Conditionally copy files in multistage dockerfile

COPY if [ "$BASE_IMAGE" = "external" ] ; then COPY --from=BUILD $TMP_LOCATION/*.properties $DEPLOYMENT_LOCATION \
			   ; COPY --from=BUILD $TMP_LOCATION/*.xml $DEPLOYMENT_LOCATION \
			   ; COPY standalone.conf /opt/wildfly/bin ; fi

May I ask where conditional operations in COPY instructions are addressed in the docs? I can not find anything like that in the COPY section of the Dockerfile referece…

The only instruction I am aware of that supports conditional operations is the RUN instruction.
