Jenkins - Master Slave set up questions

Question

I followed tutorial to get Jenkins set up on Windows.

What i have is:

Jenkins running with recommend plugins installed

Jenkins URL changed to http:// my ipv4:8080/

A project with a simple command [echo hi]

For nodes i currently have just the Master node which is tied to my main PC

My goal is have one computer send a command to all the slave PC's so they run a python script i created.

I create a windows VM and connected to the Jenkins server. I logged in with the admin account and created a new node.

I cant find anything useful to help me figure out what to put in launch command. When i launch my node on the VM without the launch command specified, it fails to launch.

Is the batch script i wrote in the project, what's sent to all the slave machines or do I have this all wrong?

Thank you!

EDIT

I got it working thanks to the answer posted here. I wrote up a doc on how i got Jenkins working from installation to deployment. There are other resources out there but i hope this will help someone.

Jenkins Master/Agent Setup

Answer 1

If you want to have the option Launch slave agents via Java Web Start you should specify the TCP port for slaves. It is done through Manage Jenkins > Configure Global Security > TCP port for JNLP agents. You can select fixed port 50000. More info here.
