How can I deploy a flow?

Prefect 2.0

In order to deploy your flow, you create a deployment, which informs Orion:

• where the flow is located (storage),
• and where to deploy your flow (flow_runner).

The Orion engine pulls the flow from the specified location and executes it on the infrastructure you defined in your FlowRunner configuration (e.g., a DockerFlowRunner deploys your flow as a Docker container). This tutorial shows how to specify and create a deployment.

Prefect 1.0

There are two components that need to be set on your flow in order to deploy it:

1. Storage - tells Prefect from where to pull the flow definition,
2. Run Configuration - tells Prefect how and where to deploy a flow run. By using labels, you can associate flows with specific agents.

Once that’s defined, you register your flow to the backend while specifying the flow path and the project name.

Note: You can think of Prefect 2.0 flow_runner as a replacement to Prefect 1.0 run_config.

Prefect 2.0 All flow runs, even those started locally, are recorded in the Orion backend. Thus, there is nothing else you need to do besides calling your main flow function. Additionally, you can start a flow run by creating and executing a deployment, attaching a schedule to your deployment, or triggering a run from the UI or API. Here is an example: prefect deployment execute 'flow_name/deployment_name’ Prefect 1.0 There are several ways to start a flow run recorded in a backend. You can …
