I was able to setup a prefect agent in kubernetes (GKE), and now I'm a little confused on next steps. If you are to create a flow deployment, does that code deployment need to be in a storage block? I'm assuming it will have to be. I tried a flow run without the storage block and got an error saying it couldn't find the flow (and it referenced my local computer's path).

In my understanding, yes you need the storage block. I recently tried this out by for example creating a new flow file, deployment etc. on my local machine, and then doing

prefect deployment build … --apply

without a storage block configured, while having my prefect config setting

PREFECT_ORION_UI_API_URL

pointing to my remote development server that actual hosts prefect and it’s agents. Without storage block configured, I got an error as well. The moment I configured a storage block, e.g. azure blob storage, then it worked

This is correct, for KubernetesJobs, local storage is not supported, so remote storage has to be configured: https://docs.prefect.io/concepts/infrastructure/?h=kubernetesjo#kubernetesjob https://docs.prefect.io/concepts/storage/
