Based on your Python code and the research, I'll help you create an equivalent
prefect.yaml
file. This YAML file will create a deployment that matches your Python-based deployment configuration. Here's the
prefect.yaml
file you should use:
Copy code
yaml
# prefect.yaml
name: cat-fact-flow-project  # project name

deployments:
  - name: my-deployment-2    # matches the name in your Python deployment
    entrypoint: "path/to/your/flow.py:cat_fact_flow"  # replace with your actual path
    work_pool:
      name: my-docker-pool-2
      job_variables:
        image: <http://my-registry.com/my-docker-image:my-tag|my-registry.com/my-docker-image:my-tag>
        push: false         # matches push=False in your Python code

build:
  - prefect.deployments.steps.run_shell_script:
      id: get-code
      script: echo "Add any build steps here if needed"

push:
  - prefect.deployments.steps.run_shell_script:
      id: push-image
      script: echo "Add push steps here if needed"
To use this deployment file: 1. Save it as
prefect.yaml
in your project root directory 2. Replace
path/to/your/flow.py:cat_fact_flow
with the actual path to your flow file and the flow function name 3. Deploy it using:
Copy code
bash
prefect deploy
A few important notes: 1. The YAML file assumes your Docker worker is already set up and running in the work pool named "my-docker-pool-2" 2. The
image
is specified under
job_variables
as this is how Docker workers expect to receive the image configuration 3. The
push: false
setting corresponds to your Python deployment's
push=False
If you need to create the Docker work pool first, you can do so with:
Copy code
bash
prefect work-pool create my-docker-pool-2 --type docker
Let me know if you need any clarification or have questions about specific parts of the configuration!

@Marvin I need help with build step, my flow is in Dockerfile.prefect_flows

Based on your requirement and the research, I'll help you create a
prefect.yaml
file that properly handles the Docker build step for your flows in
Dockerfile.prefect_flows
. Here's the updated configuration:
Copy code
yaml
# prefect.yaml
name: cat-fact-flow-project

deployments:
  - name: my-deployment-2
    entrypoint: "path/to/your/flow.py:cat_fact_flow"  # replace with your actual path
    work_pool:
      name: my-docker-pool-2
      job_variables:
        image: <http://my-registry.com/my-docker-image:my-tag|my-registry.com/my-docker-image:my-tag>
        push: false

build:
  - prefect.deployments.steps.run_shell_script:
      id: docker-build
      script: |
        docker build -t <http://my-registry.com/my-docker-image:my-tag|my-registry.com/my-docker-image:my-tag> -f Dockerfile.prefect_flows .
        # If you need to see the build output
        echo "Docker image built successfully"

push:
  - prefect.deployments.steps.run_shell_script:
      id: push-image
      script: |
        if [ "${PREFECT_PUSH_DOCKER_IMAGE:-false}" = "true" ]; then
          docker push <http://my-registry.com/my-docker-image:my-tag|my-registry.com/my-docker-image:my-tag>
          echo "Docker image pushed to registry"
        else
          echo "Skipping docker push (PREFECT_PUSH_DOCKER_IMAGE not set to true)"
        fi
To use this configuration: 1. Make sure your
Dockerfile.prefect_flows
is in the same directory as the
prefect.yaml
2. Replace
path/to/your/flow.py:cat_fact_flow
with the actual path to your flow file and flow function name 3. Deploy using:
Copy code
bash
prefect deploy
The build step will: 1. Build your Docker image using
Dockerfile.prefect_flows
2. Tag it with the specified name and tag 3. Optionally push it to your registry if you set the environment variable:
Copy code
bash
export PREFECT_PUSH_DOCKER_IMAGE=true
Some important notes: - The build step uses your custom Dockerfile (
Dockerfile.prefect_flows
) - The image name and tag in the build step match what's specified in the deployment's
job_variables
- The push step is conditional and will only push if you explicitly enable it - Make sure your Docker daemon is running and you have appropriate permissions If you want to see the build process in action, you can run:
Copy code
bash
prefect deploy --verbose
Would you like me to explain any part of this configuration in more detail? Also, if you could share the contents of your
Dockerfile.prefect_flows
, I could help ensure the build step is optimally configured for your specific setup.
