Hey @ancient-wolf-19325 Do we need to register "custom file sensor" ?

Yes, you need to register a custom file sensor before using it in Flyte. According to this discussion, extending the

FileSensor

and adding functionality requires registration of the custom sensor. Would you like more detail on how to register a custom sensor? Sources: - Can we just extend the FileSensor and add this functionality? 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.

@ancient-wolf-19325 this discussion does not have any details about registering custom sensor. Can you please give "step by step" process to register a "custom sensor"?

To register a custom sensor in Flyte, you can follow these steps: 1. Extend the BaseSensor Class: Create a new class that extends the

BaseSensor

class. Implement the

poke

method to define the condition that the sensor will check.

from flytekit.sensor.base_sensor import BaseSensor

   class CustomFileSensor(BaseSensor):
       def __init__(self, name: str):
           super().__init__(name=name)

       def poke(self, path: str) -> bool:
           # Implement your custom logic here
           return True

2. Register the Sensor: Use the

AgentRegistry

to register your custom sensor. This step ensures that Flyte recognizes your sensor as a valid task type.

from flytekit.extend.backend.base_agent import AgentRegistry

   AgentRegistry.register(CustomFileSensor())

3. Build and Deploy: Package your sensor into a Docker image and deploy it to your Flyte environment. You can use a Dockerfile similar to the one provided in the Flyte documentation.

FROM python:3.10-slim
   RUN pip install flytekit
   COPY . /app
   WORKDIR /app
   CMD ["pyflyte", "serve", "agent", "--port", "8000"]

4. Update Flyte Deployment: Update your Flyte deployment to use the new Docker image containing your custom sensor.

kubectl set image deployment/flyteagent flyteagent=your-custom-image:latest

5. Test the Sensor: Test your custom sensor in a local development environment or a Flyte cluster to ensure it behaves as expected. Would you like more information on any of these steps? Sources: - Flyte documentation 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
