NAME is a required, unique name for the work pool. Optional configuration parameters to filter work on the pool include:
Managing work pools in CI/CDVersion control your base job template by committing it as a JSON file to a git repository and control updates to your work pools’ base job templates with the prefect work-pool update command in your CI/CD pipeline.For example, use the following command to update a work pool’s base job template to the contents of a file named base-job-template.json:
prefect work-pool update --base-job-template base-job-template.json my-work-pool

​
List available work pools

prefect work-pool ls

​
Manage concurrency for a work pool

Base job template

View default base job template: 
prefect work-pool get-default-base-job-template --type process
Example prefect.yaml: 
deployments:
- name: demo-deployment
  entrypoint: demo_project/demo_flow.py:some_work
  work_pool:
    name: above-ground  
    job_variables:
        stream_output: false
Advanced customization of the base job templateFor advanced use cases, create work pools with fully customizable job templates. This customization is available when creating or editing a work pool on the ‘Advanced’ tab within the UI or when updating a work pool via the Prefect CLI.Advanced customization is useful anytime the underlying infrastructure supports a high degree of customization. In these scenarios a work pool job template allows you to expose a minimal and easy-to-digest set of options to deployment authors. Additionally, these options are the only customizable aspects for deployment infrastructure, which are useful for restricting capabilities in secure environments. For example, the kubernetes worker type allows users to specify a custom job template
to configure the manifest that workers use to create jobs for flow execution.See more information about overriding a work pool’s job variables.
