Create a GCS block
First, go to the Prefect UI and create a GCS block:
Create a deployment from CLI
This will assume that you want to run your flow in a local process, i.e. using a Process block. To use a different type of infrastructure, check recipes for Docker and Kubernetes.
prefect deployment build flows/hello.py:hello -n dev -q dev -sb gcs/dev -a
You should now see the entire project copied into your GCS bucket 
Start an agent
prefect agent start -q dev
You should see that your agent picked up the run:
You’re all set!
