问题描述
当使用Docker运行进程时，为什么连接到JMX端口（使用JConsole）非常困难。
Why is it so hard to connect to a JMX port (using JConsole), when a process is run using Docker.
当然，我将将JMX端口暴露给主机，甚至使用 Sun特定选项 Java流程（遵循）。
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 http://ptmccarthy.github.io/2014/07/24/remote-jmx-with-docker/ ).
我可以telnet到主机ip和暴露的JMX端口，这表示它是可访问的。但是我无法找出一种方法来使用JConsole并连接到在容器中运行的JMX服务。
I am 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
推荐答案
你目前看起来正确。至少尝试让它工作，我会尝试禁用auth& SSL。然后，一旦你得到它的工作，考虑重新启用任何您需要的安全性：
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:
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
