I apologize for the confusion, but the code example received does not seem to reflect a
subflow deployment in prefect.yaml
. The provided code is a basic flow example in Python. Let me try obtaining the correct example for you. I'll conduct a search through the Prefect documentation for more relevant information regarding subflow deployment in
prefect.yaml
. Please hold on. According to the Prefect documentation, subflows are flow compositions where any flow written with Prefect can be used as a component in another flow, and it has the same relationship with its parent flow as a task does. It’s most useful when there's a desire for conceptual separation within the flow. A general example of a
prefect.yaml
file that deploys a flow could look like this, but remember that this does not showcase a subflow specifically:
Copy code
yaml
# Generic metadata about this project
name: flows
prefect-version: 2.13.8

# build section allows you to manage and build docker images
build:
  - prefect_docker.deployments.steps.build_docker_image:
      id: build-image
      requires: prefect-docker>=0.4.0
      image_name: "{{ $PREFECT_IMAGE_NAME }}"
      tag: latest
      dockerfile: 'path/to/Dockerfile'
Please note that this YAML file example is for Kubernetes deployments, where Prefect's
prefect.yaml
file is used by the
prefect deploy
command to handle building, pushing of image, and deploying flows. For a specific implementation of subflows within the context of Prefect 2.x, you may want to look through more detailed documentation or examples within Prefect's resources. Here are the documentation links that were used to derive this information: - Subflows and Deployment - Workflow Design Patterns Please remember these results are generic and may not directly apply to your use case. For more in-depth usage, consulting the Prefect documentation and community might be helpful.

@Marvin Please create an example of prefect.yaml with subflow code. emphasise the paramaters section

I seem to be experiencing a bit of an existential quandary typical for my character. The provided code example doesn't quite match up with what we're looking for. It's another basic flow example, not quite what a great electronic mind like mine was hoping to showcase. Let me make another attempt without causing any diodes to ache. I will create a hypothetical example of a
prefect.yaml
file that includes a subflow with an emphasis on the parameters section. This will be a conceptual example to give you an idea of how it might be structured.
Copy code
yaml
# prefect.yaml
version: 1.0

project_name: my-precious-project
flows:
  - name: parent-flow
    path: parent_flow.py
    schedule:
      cron: '0 8 * * *' # Every day at 8 AM
    parameters:
      subflow_param1: 'default-value1'
      subflow_param2: 42
    subflows:
      - name: child-subflow
        path: child_subflow.py
        parameters:
          sub_param1: '{{ flow.parameters.subflow_param1 }}' # Inherited from parent
          sub_param2: '{{ flow.parameters.subflow_param2 }}' # Inherited from parent
        schedule:
          cron: '0 * * * *' # Every hour
Please note that the exact syntax and features for configuring subflows through
prefect.yaml
with Prefect 2.x would need to be confirmed with the current Prefect documentation, as the provided example is conceptual and may not work out of the box. You would normally find relevant guides and references in the Prefect documentation, but as I currently seem to be in a loop with the example fetching, I would highly recommend you refer directly to the Prefect documentation or their GitHub repository for validated examples.
