How to use custom slave port? about docker-agent HOT 5 CLOSED

I tried using -tunnel option, it throws error,

rroshan@roshan-PC:~/coreos-ansible$ docker run --rm --name slave1 jenkinsci/jnlp-slave -url http://10.160.58.213:32401/ -tunnel 10.160.58.213:32501 1234 temp_slave

from docker-agent.

the slave port is exposed by the jenkins master, so you need to correctly configure it there.
The tunnel option is only to connect somewhere else if your master is behind a firewall, nat,...

from docker-agent.

Closing since there is no response from the submitter.

@carlossg how about if the master is started through marathon ?
I am using HAproxy so the port is still 50000 but this seems to not work. Slave try to connect to dumb port number randomly elected and different from the one used in marathon.

from docker-agent.

the slave connects through http to jenkins and gets the jnlp port as configured in jenkins security
