How to get ip of a Jenkins' node using Jenkins API in groovy

Question

I have the following Groovy script, called by a Jenkins pipeline job:

import jenkins.model.Jenkins

def foo(){
    Jenkins.instance.getNode('bla').getComputer.disconnect()
}

Checking thegetComputer() API , I wasn't able to find a way to also get the IP of the node. Is it possible from within the jenkinsfile / groovy script?

Answer 1

This what worked for me eventually. The trick is to run it from master (so the desired node won't be recognized as "local host"

 def find_ip(node_name){
       for (slave in Jenkins.instance.slaves) {
           host = slave.computer.hostName
           addr = InetAddress.getAllByName(host)
           if (! slave.name.trim().equals(node_name.trim())) { continue }
           return host
       }
 }
