Prefect v2.0.b16 Release Notes

  • 🚀 Simplified, declarative deployments

    🚀 Prefect 2.0's deployments are a powerful way to encapsulate a flow, its required infrastructure, its schedule, its parameters, and more. Now, you can create deployments simply, with just two commands:

    1. prefect deployment build ./path/to/flow/file.py:name_of_flow_obj --name "Deployment Name" produces two files:
      • A manifest file, containing workflow-specific information such as the code location, the name of the entrypoint flow, and flow parameters
      • A deployment.yaml file - a complete specification of the metadata and configuration for the deployment such as the name, tags, and description 🚀 3. prefect deployment apply ./deployment.yaml creates or updates a deployment with the Orion server

    📚 Once the deployment is created with the Orion server, it can now be edited via the UI! See the Deployments documentation to learn more.
