@Jens Cardon heres an example of deployment that uses a variable for work pool definition + multiples schedules prefect-version: 2.10.18

definitions:
    work_pools:
        wekeo-pool: &wekeo-pool
          name: wekeo-pool
          work_queue_name: wekeo
          job_variables:
              image: '{{ build_image.image }}'

build:
- prefect_docker.deployments.steps.build_docker_image:
    id: build_image
    requires: prefect-docker>=0.3.0
    image_name: murmurationsas/orion
    tag: flow-
    dockerfile: Dockerfile
    push: True
    credentials: "{{ prefect.blocks.docker-registry-credentials.docker-hub }}"

pull:
- prefect.deployments.steps.set_working_directory:
    directory: /opt/prefect/flow/
