Hello everybody! I’m not quite sure how to use prefect, so can I ask you for advice? I want to run code on github with prefect-server. I have registered a block, registered a deployment, and in the flow log it seems that the code is being pulled, but nothing in particular is being executed. I only have the python code with the flow on github now, but do I have to put something else on github to get the code on github to run? I don’t know how to execute the code.
From local I ran the following code
Copy code
from prefect_github.repository import GitHubRepository


@flow(log_prints=True)
def git_flow(repo_name: str = "git_flow"):
    github_load = GitHubRepository.load("git_flow")

if __name__ == "__main__":
    git_flow.serve(name = "git_flow")

You need some execution environment where you code can run. Your existing flow is using 
.serve()
, which is creating a deployment on your behalf when it is executed on local. If you don't have as much experience with execution environments, I would recommend a serverless offering like Google Cloud Run or AWS ECS. You'll want to create a deployment and configure your code storage (GitHub) and a serverless worker/work pool. Creating a deployment Push work pools (a special way of using serverless with Prefect) AWS ECS example

Thank you for your reply. I would like to build on-premise due to my internet situation. I was missing an explanation, but I also ran the following and the flow is visible in the web UI.
Copy code

In addition I ran the following commands
Copy code
prefect deployment run 'get-itemname/github-get-itemname'
Sorry, the name of the flow has been changed as it contains personal information. It has a different name to the code above.
I’ve read through the prefect documentation and didn’t understand how to use github storage, so I’m sorry if I’ve misunderstood something...
I just noticed that I couldn’t pull from git. There seems to be a problem with the code. I’ll look into it a bit more. Thank you very much.
