Hi I ve been going through the Prefect tutorials using a free account I ve gotten the basic Hello World flow to run using the local agent but now I m trying to get it to run via the kubernetes agent using MacOS desktop docker I ve run the command line k8s agent as follows `prefect agent kubernetes start` When I kick off the hello world flow this indeed starts a job container on my desktop k8s which appears to start up fine and have the values that I configured eg correct image However it stays in a running state for several minutes until it errors out as follows `urllib3 exceptions MaxRetryError HTTPSConnectionPool host= port=443 Max retries exceeded with url graphql Caused by NewConnectionError lt urllib3 connection HTTPSConnection object at 0x7f5455f07710 gt Failed to establish a new connection Errno 3 Tempor` Here s the code for my flow ```import prefect from prefect import task Flow from prefect run configs import KubernetesRun task def hello task logger = prefect context get logger Hello world flow = Flow hello flow2 tasks= hello task flow run We could run our flow locally using the flow s run method but we ll be running this from Cloud flow run config = KubernetesRun env= PREFECT LOGGING LEVEL DEBUG image= prefecthq prefect latest labels= flow register project name= tester ```

my impression is that it s trying to store something in my home directory but has somehow had that configured wrongly

Kevin Kho · Answer

Hey < Ryan Sattler> it looks like you don t have Storage defined which uses `LocalStorage` and the default behavior is that it will save it in the home directory The issue here is that the `KubernetesRun` created a new pod and then looks for it locally there but doesn t find the Flow A lot of users use `DockerStorage` with `KubernetesRun` where they package everything up in a container and then pass it to the `KubernetesRun` so that the flows can be pulled from inside the container You can also use something like `S3` storage or `Git` storage and Prefect will pull the flow down and run it on top of the image specified `prefecthq prefect` in your case

hmm thanks Kevin I ll have a look into that
