🕢 Deployments now support multiple schedules 🕐

With today’s release, we’re excited to roll out initial support for using multiple schedules with Deployments! You can now use multiple schedules in the following ways:

  • Specifying schedules in a Deployment YAML file
  • Creating Python-based Deployments with the Deployment class
  • New CLI commands: prefect deployment schedule <create, delete, pause, resume, ls, clear>
  • New UI components aware of multiple schedules

Coming soon, we’ll round out support for multiple schedules in other areas, such as:

  • When running a flow with flow.serve() and flow.deploy()
  • When using prefect deploy

The easiest way to get started with multiple schedules is to try out the new CLI commands:

$ prefect deployment schedule ls happy-flow/my-deployment
                       Deployment Schedules
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━┳━━━━━━━━┓
┃ ID                                   ┃ Schedule        ┃ Active ┃
┡━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━╇━━━━━━━━━━━━━━━━━╇━━━━━━━━┩
│ c7d3ddc4-9a5a-4dec-bd59-eed282ae55d5 │ cron: 0 0 1 * 1 │ True   │
└──────────────────────────────────────┴─────────────────┴────────┘

$ prefect deployment schedule create happy-flow/my-deployment --interval 60
Created deployment schedule!

$ prefect deployment schedule ls happy-flow/my-deployment
                         Deployment Schedules
┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━┓
┃ ID                                   ┃ Schedule           ┃ Active ┃
