prefect deploy
This will use the configuration from your prefect.yaml
file. If you want to deploy a specific flow, you can also specify the entrypoint directly:
bash
prefect deploy src/flows/my_flow.py:my_flow
Remember:
1. Always run deployment commands from your project root directory
2. Make sure all necessary __init__.py
files are present in your directory structure
3. If your flow has dependencies, list them in requirements.txt
4. The paths in entrypoint
should always be relative to where your prefect.yaml
is located
This configuration ensures that Prefect can properly locate and run your flow, even when it's in a subdirectory of your project.Julien

file is in the project
and my script is located in project/src/main.py
so I set the entrypoint
to src/main.py
But I always get the error "file not found" and he's trying to load the file from the root, and not relatively to the prefect.yml fileMarvin

2. How to handle the paths when running inside Docker
Here's how to fix it:
1. First, let's verify your project structure:
project/
├── prefect.yaml
└── src/
└── main.py
2. In your prefect.yaml
, you need to ensure two things:
- The correct entrypoint path
- A proper working directory setup
Here's the corrected prefect.yaml
configuration:
yaml
name: your-project-name
prefect:
version: 3.x
deployments:
- name: your-deployment-name
version: null
tags: []
description: "Your deployment description"
entrypoint: "src/main.py:your_flow_function" # Relative to prefect.yaml
work_pool:
name: your-work-pool
# Add this pull step to ensure correct working directory
pull:
- prefect.deployments.steps.set_working_directory:
directory: "." # This sets the working directory to where prefect.yaml is
3. If you're using Docker, make sure your volume mounts are correct. Your Docker Compose file should include something like:
yaml
services:
prefect-worker:
# ... other configuration ...
volumes:
- ./:/app # Mount the entire project directory
working_dir: /app # Set the working directory to match your mount point
4. When deploying, make sure you're running the deploy command from the same directory where your prefect.yaml
is located:
bash
prefect deploy
Key points to remember:
1. The entrypoint
path in prefect.yaml
should always be relative to the location of the prefect.yaml
file
2. The set_working_directory
step ensures Prefect knows where to look for files
3. If using Docker, make sure your volume mounts and working directory are correctly configured
If you're still having issues, could you share:
1. Your Docker configuration (if you're using Docker)
2. The exact error message you're getting
3. The command you're using to deploy
This will help me provide more specific guidance for your setup.
