I'm new to JProfiler. I came into a problem recently. My Java app is running in docker which means the JVM is runnning in docker. But my jprofile is installed in the host machine. I know the jprofiler must connect to a JVM. So, is there anyway that the jprofiler can connect to jvm running in docker?
It is similar as connects JProfiler to a remote JVM, you just need to have the JProfiler agent ready inside your container and expose the port.
This post has a step by step guide http://geekspearls.blogspot.com.au/2016/08/configure-jprofiler-92-to-profiling.html
You can use this dockerfile; https://registry.hub.docker.com/u/gingerbeard/java8-jprofiler/dockerfile/
FROM dockerfile/java:oracle-java8

RUN wget http://download-aws.ej-technologies.com/jprofiler/jprofiler_linux_8_1_2.tar.gz -P /tmp/ &&\
tar -xzf /tmp/jprofiler_linux_8_1_2.tar.gz -C /usr/local &&\
rm /tmp/jprofiler_linux_8_1_2.tar.gz
ENV JPAGENT_PATH="-agentpath:/usr/local/jprofiler8/bin/linux-x64/libjprofilerti.so=nowait"
EXPOSE 8849
CMD ["bash"]
make sure to check the ports.
The JProfiler GUI connects to the profiling agent that is loaded in the profiled JVM through a TCP socket.
This is always the case, also if the profiled JVM and the JProfiler GUI are running on the same machine.
Invoking "Session->Integration wizards->New remote integration" will give you the instructions to set this up manually.
