Create Jenkins slave from command line

Question

I have a script that create a VM then I need to add the new VM as a slave to existing master,
How can I do that from command line in windows and from the new VM ?

Answer 1

Create a VM (OS = WINDOWS)

Create a Node on jenkins server from command line using jenkins cli:

config.xml | ssh -l fmud -p %JNLP_PORT% %jenkins_IPADDRESS% create-node %TARGET_WIN_NODE_NAME% 

Where Config.xml could be gathered from an existing slave with command:

ssh -l fmud -p %JNLP_PORT% %jenkins_IPADDRESS% get-node %TARGET_WIN_NODE_NAME%

Note: JNLP is needed for jenkins-CLI and could be configured in jenkins administrative page.

Also, you will have to change the config file with label and name etc.

• Connect the windows slave as service: Download winsw.exe
• Rename it to jenkins_slave.exe
• Download slave.jar (http://yourserver:port/jnlpJars/agent.jar )
• Download and configure jenkins-slave.xml
• Download and configure jenkins-slave.exe.config
• in cmd: jenkins_slave.exe install
• jenkins_slave.exe start

If it is a java slave, that is simple to automate. Like it if you find it helping or ask more specific question otherwise.
