Executing Tasks on All Resources in a Pool
Creating resource pools (grouping resources) means you can reference many resources using one name, the pool name. When configuring a step, you can "broadcast" the step to all resources in a pool. For example, you might want to start an application or microservice deployment at the same time on all resources in a pool. This tutorial shows how to group resources into a resource "pool".

An explanation of what you see:
This procedure implements three steps:
The first step,
Setup environment, creates a pool for resources.
Clicking on the step name takes you to the Edit Step page to see the full command text supplied to create this step—a partial section is displayed in the Action column.
Functionality to create this step is beyond the scope of this tutorial. For more information, see the link to "Using ectool and the CloudBees CD API" below.
The following resources were created and added to a pool named EC-Tutorial-pool: EC-Tutorials-resource1 EC-Tutorials-resource2 EC-Tutorials-resource3
The second step,
Execute command on all resources in pool, executes an echo statement on the resource EC-Tutorial-pool and has the "broadcast" option selected, which results in the step executing on all resources in the pool simultaneously.
The third step,
Cleanup, deletes the resources created in the
