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?

But the answer of that question is not the same thing I asked – shawn Aug 09 '16 at 21:08

remote just means a subset of anything you can also do locally or with containers, therefore it is applicable here. – the8472 Aug 09 '16 at 22:28

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

I found I had to map the port after following the guide. docker run -p 8849:8849 imageName – Will Humphreys Apr 29 '17 at 19:40

You can use this dockerfile; https://registry.hub.docker.com/u/gingerbeard/java8-jprofiler/dockerfile/
FROM dockerfile/java:oracle-java8
MAINTAINER gingerbeard <kulishovt@gmail.com>
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.

1I've figured it out. The right way is install jprofiler inside the container with your java app. Start the jprofiler using "docker exec" in your host machine. Then u can monitor your container in your local machine. – shawn Aug 10 '16 at 18:36
