Manage Worker Nodes
Bring up a New Worker Node
Jenkins → Manage Jenkins → Manage Nodes
To bring up a new type of worker node, navigate to the bottom and use the "Provision with node-type" dropdown box.
Configure a New Worker Node Type
Jenkins → Manage Jenkins → Configure System
A node type is known as a "Cloud", so the configuration lives in the "Cloud" section.
The name of the worker type is technically the "name of the Jenkins could of agents".
We want an "Amazon EC2" type of cloud. The "Amazon EC2" could is capable launching multiple types of workers, based on different AMIs..
