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

Answer:

You have to expose the JMX port to the host and even used Sun specific options while running the Java process.
You are able to telnet to the host ip and the exposed JMX port, which tells that it is accessible. But I can't figure out a way to use JConsole and connect to the JMX service running in the container.
☛ Djava.rmi.server.hostname=$JMX_HOSTNAME
☛ Dcom.sun.management.jmxremote.port=$JMX_PORT
☛ Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT
