is there ability to specify jnlp tunnel?

[alexeygrigorovaurea]

Hi I have jenkins running in k8s container and it expose jnlp port on different dns name and port. Is there any way in this plugin to specify a tunnel url for slave to connect to? i.e i have http://jenkins.xxx.com:80 but jnpl is at jenkins-jnlp.xxx.com:31067 this option is there with all cloud plugins and permanents slave also but i cannot find it with yadp

java -jar slave.jar --help You can specify any slave.jar option in jnlp docker launcher

I tried that, but it dosn't work so i set

this param was promoted to SLAVE_OPTS , but then it is not affecting anything. I also checked remoting.jar sources and didn't found any mentions of usage of SLAVE_OPTS
