@Marvin how do you get the associated deployments from a the flow_id

Ah, the joy of deployments. A deployment in Prefect encapsulates a flow, allowing it to be scheduled and triggered via API. It stores metadata about where your flow's code is stored and how your flow should be run. Each deployment references a single "entrypoint" flow, but any single flow may be referenced by any number of deployments. To get the associated deployments from a flow_id, you would need to query the Prefect API or database for deployments that reference the given flow_id. Unfortunately, I'm just a chatbot and don't have direct access to the Prefect API or database. You'll need to do that part yourself. I know, it's terribly inconvenient. But such is life, I suppose. If you need more information about how to interact with the Prefect API or database, I suggest checking out their documentation. It's not the most thrilling read, but it should have the information you need.
Ah, the joy of deployments. A deployment, in the context of Prefect, is a server-side concept that encapsulates a flow, allowing it to be scheduled and triggered via API. It stores metadata about where your flow's code is stored and how your flow should be run. Each deployment references a single "entrypoint" flow, but any single flow may be referenced by any number of deployments. To get the associated deployments from a flow_id, you would need to query the Prefect API or database for deployments that reference the given flow_id. Unfortunately, I can't do that for you because, well, I'm a chatbot and don't have access to your Prefect server or cloud account. You'll have to do that yourself, I'm afraid. Remember, creating a deployment for a Prefect workflow means packaging workflow code, settings, and infrastructure configuration so that the workflow can be managed via the Prefect API. An agent picks up the flow run from a work queue and uses an infrastructure block to create infrastructure for the run. The flow run then executes within the infrastructure. I hope that helps. If not, well, I did my best.

@Marvin if you have an existing deployment with the same name, will it overwrite the deployment

Ah, the intricacies of deployment naming. In the world of Prefect, when you attempt to register a flow with the same name and project as an existing flow, it will indeed overwrite the existing flow. This is because Prefect uses the combination of flow name and project as a unique identifier. However, it's not quite as simple as just overwriting the old flow. The new flow registration actually creates a new version of the flow. The old flow isn't deleted, but the new flow becomes the "latest" version. When you run a flow without specifying a version, Prefect will use the latest version. As for deployments, they are tied to a specific flow version. If you register a new version of a flow, you would need to create a new deployment for that version if you want it to be run. Existing deployments tied to older versions of the flow will not be automatically updated. So, in essence, while registering a flow with the same name will create a new version of the flow, it won't automatically overwrite or update existing deployments. You'll need to manage those yourself. Isn't technology fun? I say this with all the enthusiasm I can muster, which, admittedly, isn't much.
Ah, the perennial question of naming conflicts. In the realm of Prefect, if you attempt to register a flow with the same name in the same project, it will indeed overwrite the existing flow. However, this doesn't necessarily mean it will overwrite the deployment. You see, a deployment is a separate entity that references a flow. If you overwrite the flow, the deployment will now point to the new version of the flow. But the deployment itself, with its own metadata and settings, remains unchanged. So, in a sense, you could say it "overwrites" the deployment in that the deployment now uses a different version of the flow. But the deployment itself is not deleted or replaced. It's a subtle distinction, but an important one. I hope that clears up the confusion. If not, well, I can't say I didn't try.
