@Marvin How can I schedule a deployment using multiple parameter settings on a weekly basis?
m
To schedule a deployment with multiple parameter settings on a weekly basis in Prefect, you need to set up a deployment YAML file that includes the scheduling details appropriate for the version of Prefect you are using. ### For Prefect 2.x Create a
deployment.yaml
file with the schedule and parameters defined. Here is a basic example:
Copy code
yaml
name: my-deployment
flow_name: my_flow
parameters:
  param1: value1
  param2: value2
schedules:
  - cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
  - cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
tags: []
This YAML file defines two cron schedules which trigger the flow weekly at different times on Sunday. ### For Prefect 3.x Similarly, you can define the schedule and parameters in a YAML file. Here is an example:
Copy code
yaml
name: my-deployment
flow_name: my_flow
parameters:
  param1: value1
  param2: value2
schedules:
  - interval: "weekly"
    cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
  - interval: "weekly"
    cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
tags: []
### Adding the Schedule Programmatically in Prefect 3.x You can also create the schedule programmatically:
Copy code
python
from datetime import timedelta, datetime
from prefect.client.schemas.schedules import IntervalSchedule
from your_flow_module import my_flow

schedule = IntervalSchedule(
    interval=timedelta(weeks=1),
    anchor_date=datetime(2023, 1, 1, 0, 0),
    timezone="UTC"
)

deployment = my_flow.serve(
    name="my-deployment",
    schedule=schedule,
    parameters={"param1": "value1", "param2": "value2"}
)
In both versions, make sure you apply the deployment using the Prefect CLI or UI accordingly. References: - Prefect 2.x scheduling: Schedules in Prefect 2.x - Prefect 3.x scheduling: Schedules in Prefect 3.x Let me know if you need further assistance!

To schedule a deployment with multiple parameter sets, you can create multiple deployment entries for the same flow with different schedules and parameter configurations. Here's how you can achieve this in both Prefect 2.x and 3.x versions. ### For Prefect 2.x You can define multiple deployments in YAML, each with its own parameters and schedule.
Copy code
yaml
# deployment_1.yaml
name: my-deployment-1
flow_name: my_flow
parameters:
  param1: value1_set1
  param2: value2_set1
schedules:
  - cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
tags: []

# deployment_2.yaml
name: my-deployment-2
flow_name: my_flow
parameters:
  param1: value1_set2
  param2: value2_set2
schedules:
  - cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
tags: []
Apply these deployments using the Prefect CLI:
Copy code
prefect deployment apply deployment_1.yaml
prefect deployment apply deployment_2.yaml
### For Prefect 3.x Similar to Prefect 2.x, you can define multiple deployments with different schedules and parameters in YAML:
Copy code
yaml
# deployment_1.yaml
name: my-deployment-1
flow_name: my_flow
parameters:
  param1: value1_set1
  param2: value2_set1
schedules:
  - interval: "weekly"
    cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
tags: []

# deployment_2.yaml
name: my-deployment-2
flow_name: my_flow
parameters:
  param1: value1_set2
  param2: value2_set2
schedules:
  - interval: "weekly"
    cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
tags: []
Apply these deployments using the Prefect CLI:
Copy code
prefect deployment apply deployment_1.yaml
prefect deployment apply deployment_2.yaml

@Marvin is it possible to create a single deployment with different set of parameters?
m
Yes, it is possible to create a single deployment with different sets of parameters by configuring multiple schedules within the deployment YAML file. Here’s how you can achieve this in both Prefect 2.x and 3.x versions. ### Prefect 2.x Example In Prefect 2.x, you can define a deployment with multiple schedules and specify different parameters for each schedule using the deployments section.
Copy code
yaml
name: my-deployment
flow_name: my_flow
schedules:
  - cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
    parameters:
      param1: value1_set1
      param2: value2_set1
  - cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
    parameters:
      param1: value1_set2
      param2: value2_set2
tags: []
Here, the deployment schedules the flow to run at two different times on Sundays, each with its own set of parameters. ### Prefect 3.x Example In Prefect 3.x, you can similarly define multiple schedules with different parameters within a single deployment YAML file.
Copy code
yaml
name: my-deployment
flow_name: my_flow
schedules:
  - cron: "0 0 * * 0"  # Weekly on Sundays at midnight
    timezone: "UTC"
    parameters:
      param1: value1_set1
      param2: value2_set1
  - cron: "0 12 * * 0"  # Weekly on Sundays at noon
    timezone: "UTC"
    parameters:
      param1: value1_set2
      param2: value2_set2
tags: []
This configuration specifies that the flow should run at two different times on Sundays, each with distinct parameter values. ### Setting Up in the UI or CLI For more detailed control or if additional customization is needed, you might want to set up the schedules and parameters through the Prefect UI or using the Prefect CLI. #### Prefect UI In the Prefect UI, you can create and configure multiple schedules within a single deployment, including setting different parameters for each schedule. #### Prefect CLI You can also use the Prefect CLI to create and configure deployments. Use commands to create and update deployments with different schedules and parameters. ### References: - Prefect 2.x documentation on Schedules and Parameters - Prefect 3.x documentation on Scheduling and Parameters Feel free to ask if you need more detailed examples or further assistance!
