Hi, I'm wondering if there's a simple solution to updating flows in prefect? For example, I have a flow script, I create the manifest of the flow, and then apply the deployment to prefect server. If for some reason I have to update that specific flows script, how do I go about letting prefect know that there's an update for the flow I previously deployed? Can prefect pull updates from github or any other third party service? Do I have to remove the flow and re-do the manifest and apply a new deployment? I'm just looking to understand if this type of functionality currently exists or if someone can point me to the right documentation when it comes to this type of functionality.

You don’t have to remove the flow. After updating the flow, you can update the deployment with the

prefect deployment build

command

the storage block only points to the location on remote storage -- this means that as soon as you reupload your code to S3 (you can do it using build CLI as Khuyen mentioned or upload it yourself), Prefect will automatically pick up the changes; in the same way if you use GitHub block, Prefect always clones the repo at runtime so you only need to remember to commit and push your code

So if I'm storing my flows in github and I have an a agent already running -- it clones done the flow from github and runs it. Then 5 minutes later I update the flow in github, the agent will not pull down the new changes from github until I re-run prefect deployment build once again? Am I tracking correctly what is being said?

you only need to commit + push your code, deployment only points to the storage

ahhh okay, gotcha. Thanks!

you can either follow this issue https://github.com/PrefectHQ/prefect/issues/6669 or use the workaround shared there
