No. And I also don't quite understand how that should work, as the IP of the
container is not known to the outside world. Anyway, this is what I did...

System props:
-Dcom.sun.management.jmxremote.ssl=false 
-Djava.rmi.server.hostname=$DOCKERHOST_HOSTNAME

org.apache.karaf.management.cfg:
rmiRegistryHost = $DOCKER_CONTAINER_IP
rmiServerHost = $DOCKER_CONTAINER_IP

New connection in jconsole: $DOCKERHOST_HOSTNAME:1099
(1099 on the host is forwarded to 1099 in the container)

Result:
Caused by: java.rmi.NotBoundException: jmxrmi

If I change this to
rmiRegistryHost = $DOCKER_HOST_IP
rmiServerHost = $DOCKER_HOST_IP

I get 

java.rmi.ConnectIOException: error during JRMP connection establishment;
