How can I add Jenkins slave nodes via the CLI?

Question

As per the title, in Jenkins how can I add new slave nodes to my build cluster using the CLI, or if there is not a CLI option, is there another scriptable approche that can be used?

Answer 1

Basic CLI instruction can be found here.

The following CLI command should get the new node configuration XML as stdin:

java -jar jenkins-cli.jar -s [JENKINS_URL] create-node [NewNodeName]

For example, if you want to copy an existing node, you can use:

java -jar jenkins-cli.jar -s [JENKINS_URL] get-node [NodeToCopyFrom] | java -jar jenkins-cli.jar -s [JENKINS_URL] create-node [NewNodeName]
