How to include Yourkit inside a neo4j docker image? - docker

Question

while trying to use the 3.5.5 enterprise Dockerfile (https://github.com/neo4j/docker-neo4j-publish/blob/master/3.5.5/community/Dockerfile) and to add YourKit's Docker related commands (https://www.yourkit.com/docs/java/help/docker.jsp)
so first I tried to docker build the Dockerfile without the Yourkit changes but I get this error:

Once this works I will add the yourkit specific RUN commands.

One could simply do the following instead:
FROM neo4j:3.5.5
RUN wget https://www.yourkit.com/download/docker/YourKit-JavaProfiler-2019.1-docker.zip -P /tmp/ && \
unzip /tmp/YourKit-JavaProfiler-2019.1-docker.zip -d /usr/local && \
rm /tmp/YourKit-JavaProfiler-2019.1-docker.zip
RUN apk add --no-cache --quiet libc6-compat
ENV PATH "${NEO4J_HOME}"/bin:/lib64:$PATH
ENV LD_LIBRARY_PATH /lib64:$LD_LIBRARY_PATH
VOLUME /data /logs
EXPOSE 7474 7473 7687 10001
ENTRYPOINT ["/sbin/tini", "-g", "--", "/docker-entrypoint.sh"]
CMD ["neo4j"]
