@Marvin When running my ecs task, why does it say Flow run 'idealistic-barnacle' - Downloading flow code from storage at None? My flow code is baked into a docker image, and my flow code involves downloading image raw data from s3 (which has nothing to do with the actual flow code)

When you're seeing a message like "Flow run 'idealistic-barnacle' - Downloading flow code from storage at None," it's usually a sign that your Prefect setup is expecting to fetch the flow code from a storage location that either isn't configured correctly or isn't needed in your use case. ### Possible Reasons and Solutions: 1. Storage Configuration: - Prefect might be looking for a storage option (like S3, GitHub, or local) that hasn't been specified or is set to

None

. If your flow code is indeed baked into a Docker image, make sure you've configured your flow's storage to reflect this. Ensure you're using

Docker

storage in Prefect if you want to run flows packaged in Docker images. 2. Flow Registration: - When registering your flow, ensure that it's done with the correct storage setting. Even if the code is in a Docker image, Prefect will attempt to interpret any storage information that you've provided during the flow registration process. 3. Misleading Message: - Sometimes, this message can be misleading if the storage parameter isn't the actual problem. Prefect is trying to access storage specified in your flow configuration, but if everything else works, it might just be a harmless log message. ### Actions to Consider: - Double-check and update your flow's configuration if needed to ensure that it correctly refers to Docker storage. - Check your

prefect

version and refer to the relevant documentation for setting up

Docker

storage, as there might be changes or specific requirements in different versions. Let me search for any documentation or known issues related to this scenario. Hang tight, and I'll fetch you some additional information! It seems like there was an issue with retrieving specific documentation, but I was able to find some relevant GitHub issues that might provide insight into your problem. 1. Duplicate Flow Executions in Kubernetes: - There was a reported issue where duplicate executions of flows occurred in Kubernetes environments, particularly when retries were enabled. You can check this issue on GitHub. Though not exactly the same, it might give some hints if there's a misconfiguration or misunderstanding in your setup. 2. Using Dask Task Runner causing unintended behaviors: - Another issue involved the use of

DaskTaskRunner

, where Prefect wasn't resolving futures as expected. This may not be directly related, but any intertwined configuration might cause Prefect to behave unpredictably in a different task or storage setup. You can see more on this GitHub issue. 3. Race Conditions and State Management: - There are known issues related to race conditions affecting the state of deployments, leading to stuck states or unintended cancellations. Details on this issue might not address your specific situation but can provide context on problematic orchestrations. In your case, verify if the storage method in your flow configuration matches with Docker, and ensure that any unrelated storage definitions are cleared. Sometimes the message "storage at None" could be a misleading side effect of a configuration oversight elsewhere in your flow settings. I recommend reviewing your Prefect version and any setup guides for using Docker storage to confirm everything aligns. If you've ensured your configuration is right and you're still seeing issues, consider updating Prefect to a newer version if available, as your issue might be resolved in more recent releases. If you're keen on more nuanced troubleshooting, engaging with the Prefect community forums or GitHub Discussions can also be helpful, especially if you're dealing with a niche setup. And remember, it wouldn't be a proper Prefect challenge if it didn't require a bit of sleuthing!
