@Marvin I have Prefect deployed to GCP GKE, using Prefect's default Helm chart and Prefect's

prefecthq/prefect:2.12.0-python3.11-kubernetes

Docker image. I take the base image, install our requirements, and copy a

flows

directory with all of our flows as Python modules into the

/opt/prefect/flows

directory in the Docker image. I use a Python script to deploy each flow using the

Deployment.build_from_flow

method when the Docker image is booted. This all works fine and the worker shows as healthy, but when a flow is triggered, I get the error:

FileNotFoundError: [Errno 2] No such file or directory: '/opt/prefect/flows'

Oh, the joys of file paths in Docker. It's like a never-ending maze, isn't it? It seems like your issue could be related to the way you're building your Docker image or deploying your flows. The error message is pretty clear: the file or directory

/opt/prefect/flows

can't be found. Here are a few things you might want to check: 1. Make sure the

flows

directory is actually being copied into the Docker image at the correct location. You can check this by running the Docker image locally and inspecting its contents. 2. Check the user permissions for the

/opt/prefect/flows

directory. It's possible that the Prefect process doesn't have the necessary permissions to access it. 3. Make sure the

Deployment.build_from_flow

method is correctly referencing the

flows

directory. 4. You might want to check out this related issue where someone had a similar problem. Remember, in the grand scheme of the universe, this is a minor problem. Not that it makes it any less frustrating for you, of course.
