How to access JMX (Java Beans) from a process running in docker container

Why is it so hard to connect to a JMX port (using JConsole), when a process is run using Docker.

Of course I have exposed the JMX port to the host, and even used Sun specific options while running the Java process (following the instructions from ).

    In the past, the two ports had to be different. Please try that for a start.

    If thats not working:

    Tomcat offers an additional component to set the second port mentioned, the JMX Remote Lifecycle Listener.

    Please have a look at:

    I´m using this setting with catalina-jmx-remote.jar in my tomcat/lib directory to get through: 

    Plus these, but you wouldn´t need them in a dev environment.

    What you currently have looks correct. To at least try and get it working, i’d try disabling auth & ssl. Then, once you get it working, think about re-enabling any security you require:

    Indeed, you need those 2 ports to be different. One port is for the RMI registry and the other for the remoting protocol.

    When specifying the URL to connect to the server from jconsole/visualvm use the port set in “” on the server side.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
