VisualVM unable to connect remote tomcat in docker with RMI

Question

I am runing tomcat in a docker container on a remote machine. Now I want to use VisualVM to connect. My docker start command:

docker run -d --name tomcat -p 26000:8080 -p 9090:9090 -p 9091:9091 -v /data/docker/tomcat/webapps:/data/tomcat/webapps -v /data/docker/tomcat/logs:/data/tomcat/logs -e CATALINA_OPTS="-Xms2048M -Xmx2048M -XX:MaxPermSize=256M -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=9090  -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=127.0.0.1"  my.private.hub/tomcat:latest

And the catalina.log:

But VisuamVM is unable to connect:

'Cannot connect using service:jmx:rmi:///jndi/rmi://192.168.0.119:9090/jmxrmi'

where 192.168.0.119 is the address of the remote host machine.

Answer 1

this

-Djava.rmi.server.hostname=127.0.0.1

should use your docker host machine ip that you use for your connection to it

-Djava.rmi.server.hostname=192.168.0.119

Answer 2

I tried the Marco's answer ( also answered here ) but no way.

At the end I could connect using a SSH tunnel .
