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 --name dev --tag dev --storage-block gcs/dev
prefect deployment apply deployment.yaml
You should now see the entire project copied into your GCS bucket 
When you run the build and apply commands, you should expect output similar to:
Start an agent
prefect agent start --tag dev
You should see that your agent picked up the run:
You’re all set!
