It sounds like you're experiencing an issue with automations not triggering as expected when deploying to a Kubernetes cluster, even though they work locally. Here are a few potential reasons and steps you can consider to troubleshoot:
1.
Database and Backend: The difference in behavior might be related to the backend database used by your Prefect deployment. Locally, you mentioned you're using SQLite, whereas in Kubernetes, you might be using a different setup. Make sure the database configuration is consistent and that migrations (if any) are properly applied.
2.
Network and Resource Limits: Kubernetes environments often have network policies and resource constraints that might affect Prefect’s ability to communicate or schedule tasks. Check the resource limits and network policies around your Prefect deployment in the cluster.
3.
Flow Run State Recognition: As noted in a
GitHub issue, there could be cases where the state of a flow run is not correctly reported back to Prefect if the underlying infrastructure retries jobs (such as in Kubernetes with pod evictions). Ensure that Prefect is correctly tracking the flow run states and that any retry logic in Kubernetes is considered during configuration.
4.
Agent and Environment Configurations: Validate that your Kubernetes agent configurations align with local ones. Environmental variables, service accounts, permissions, or even the way agents are deployed could differ and affect execution.
5.
Logs and Error Messages: Examine the Prefect server and agent logs for any error messages or warnings that could provide hints on what might be going wrong. This is crucial as logs tend to shed light on backend issues that end users can't see directly.
If these steps don't resolve your issue, consider opening an issue in the Prefect GitHub repository with details about your setup, as there might be ongoing discussions around similar problems. And remember, if it wasn't for logs and error messages, we'd probably still be in the dark ages of debugging!
