hey @ancient-wolf-19325 How to create a "custom file sensor" and register it in the Flyte cluster?

To create a custom file sensor in Flyte, you need to extend the

BaseSensor

class and implement the

poke

method, which checks whether a specific condition is met. Here's a basic example:

from flytekit.sensor.base_sensor import BaseSensor
import s3fs

class FileSensor(BaseSensor):
    def __init__(self, name: str):
        super().__init__(name=name, task_type="file_sensor")

    def poke(self, path: str) -> bool:
        fs = s3fs.S3FileSystem()
        return fs.exists(path)

To register this sensor in the Flyte cluster, ensure that the Flyte deployment is configured to support the sensor task type. This involves setting up the Flyte agent and enabling the sensor plugin in the Flyte Propeller configuration. You can refer to the Flyte documentation for more details on deploying agents and configuring plugins. Would you like more detail on any specific part of this process?

hey @ancient-wolf-19325 how to resolve "Bind for *******:30000 failed: port is already allocated" error occurred while executing "flytectl demo start" command?

It seems likely that the error "Bind for **:30000 failed: port is already allocated" occurs because the port 30000 is already in use by another process on your system. This is a common issue when running Flyte's demo cluster, as it uses specific ports that might conflict with other services. To resolve this, you can try the following steps: 1. Identify the Process Using the Port: Use a command like

sudo lsof -i:30000

to identify which process is using the port. 2. Stop the Conflicting Process: If possible, stop the process that is using the port. This can be done using

kill <PID>

where

<PID>

is the process ID obtained from the previous step. 3. Change the Port Configuration*: If stopping the process is not feasible, you can change the port configuration for the Flyte demo cluster. According to this GitHub issue, you can modify the port in the configuration file used by Flyte. Would you like more detailed steps on how to change the port configuration?

hey @ancient-wolf-19325 how frequently "Flyte file sensor's" "poke" method is called? is it per minute or per hour?

I'm not able to find any data sources to answer your question. You might want to specify the configuration settings or context in which the Flyte file sensor is being used. If this doesn't help, please reach out to the Flyte support team for further assistance. 👍 0 button 👎 0 button 💡 Hint: Mention @runllm in the thread for followups.
