Finding IP of a Jenkins node
JenkinsJenkins Problem Overview
A windows slave node connected to Jenkins server through "Java web start". The system information of the node doesn't have it's IP address.
I had to run through all the slaves node we had, and find which machine (ip address) corresponds to the slave node in Jenkins.
Is there a way to find the IP address of a slave node from Jenkins itself?
Jenkins Solutions
Solution 1 - Jenkins
Through the Script Console (Manage Jenkins -> Nodes -> Select a node -> Script Console) of the node we can execute groovy script. Run the following command to get the IP address.
println InetAddress.localHost.canonicalHostName
Solution 2 - Jenkins
The most efficient and platform-independent way to find out the IP is probably the following groovy code for the "global" Script Console on the master:
import hudson.model.Computer.ListPossibleNames
def node = jenkins.model.Jenkins.instance.getNode( "myslave" )
println node.computer.getChannel().call(new ListPossibleNames())
In the console, this yields (for example)
Result
[192.168.0.17]
The result is a list of strings, as there's potentially multiple IP addresses on one machine.
Since this does not require the node-specific consoles, it's easy to add a loop around the code that covers all nodes.
Solution 3 - Jenkins
To answer this same question on a non-windows Jenkins slave:
Get the IP address:
println "ifconfig".execute().text
Get the hostname:
println "hostname".execute().text
Solution 4 - Jenkins
From the Web Interface
Go to the node's Log link:
http://jenkins.mycompany.com:8080/computer/my_node_name/log
The first line should say something like:
JNLP agent connected from /10.11.12.123

Solution 5 - Jenkins
This is very similar to what deepak explained but I added images along the short steps.
In Jenkins UI click:
Manage Jenkins -> Nodes -> Select a node -> Script Console
then run println InetAddress.localHost.canonicalHostName
Solution 6 - Jenkins
To get the ip on a Windows slave:
Navigate to the Script Console (Manage Jenkins -> Nodes -> Select a node -> Script Console)
println "ipconfig".execute().text
Solution 7 - Jenkins
In your Jenkins job if its in groovy or else echo the ifonfig sh "/sbin/ifconfig -a | grep inet"
Solution 8 - Jenkins
Can also be found through the Jenkins UI: Manage Jenkins --> Manage Nodes --> Click Node name --> Configure
This should display both the public and private ip address of that node
