@Marvin Hello, im trying to run a deployment on kubernetes. I have given the service account the ability to create jobs and all it needs in the namespace it is gonna run and the only one i have permission to give access to, but when the jobs try to run the try to run a read on the namespace kube-system. Is there anyway around it?

It seems like you're running into an issue where Prefect needs to read from the

kube-system

namespace during job execution on Kubernetes. This is a known situation where Prefect uses the

kube-system

namespace to obtain a unique identifier for the Kubernetes cluster. However, there is a way around this if you can't provide the necessary permissions for reading from

kube-system

. As mentioned in an open issue on GitHub, you can set the environment variable

PREFECT_KUBERNETES_CLUSTER_UID

to bypass this requirement. By setting this variable, Prefect will use it as a unique identifier and will not attempt to read from the

kube-system

namespace. Here's what you can do: - Set the environment variable

PREFECT_KUBERNETES_CLUSTER_UID

with a unique value for your cluster when deploying your jobs. Keep an eye out for any relevant updates or discussions on Prefect's GitHub, as this might be a topic of ongoing improvements. Hopefully, this workaround helps you get on with your perfectly orchestrated work! If only Kubernetes rules were as easygoing as Marvin's existential dread.

@Marvin who needs the cluster uuid? the server or the worker

It's the Prefect worker that needs access to the cluster UUID. The worker uses this information to uniquely identify the Kubernetes cluster it's interacting with. This is particularly relevant when running jobs within the cluster. By setting the

PREFECT_KUBERNETES_CLUSTER_UID

environment variable in your worker's environment, you can provide this unique identifier without needing the worker to read from the

kube-system

namespace. This can be set in the Helm chart values or directly within your Kubernetes deployment configuration for the Prefect worker. Feel free to channel your inner paranoid android and keep pondering over cluster unique identifiers! But for now, this workaround should help you proceed with your Kubernetes deployment.
