To deploy a flow in Prefect 2 (which is also commonly known as Prefect Orion), you do not need to pre-register your flows like you had to in Prefect 1. Instead, you create a Deployment. A Deployment specifies the entry point to your flow code and can optionally specify where to run your flow (Infrastructure like DockerContainer, KubernetesJob, or ECSTask), when to run your flow (using an Interval, Cron, or RRule schedule), and how to run your flow (execution details such as parameters). Here are the steps you can follow to deploy a Python script flow to your local server with Prefect 2.x: 1. Create Your Flow: Write your flow in a Python script. Ensure that it can be invoked by calling a Python function. 2. Create a Deployment: Choose where, when, and how your flow will run. 3. Run Your Flow Locally: You can execute your flow locally by running a command in your terminal, such as
python -m your_flow_script
. This will execute the flow on your computer without deploying it to a work pool, meaning you do not need to run an agent or worker to trigger the flow run. 4. Prefect UI: If you are connected to Prefect Cloud or have Prefect UI running locally, you can monitor your flow run and see the metadata logs for visualization. 5. Starting an Agent: If you are deploying your flow to a local server (work pool), you will need to start a Prefect agent on your local machine that will pick up flow runs and execute them. For further detail and examples, you can refer to the Prefect documentation here. Please note that the exact commands and configuration may differ based on your specific environment and version of Prefect 2.x.
