@Marvin Hi, I am using DeploymentEventTrigger, how could I get partial arguments from upstream deployment, and pass these arguments to triggered deployment?

To pass partial arguments from an upstream deployment to a triggered deployment using

DeploymentEventTrigger

, you can utilize Jinja templates to render the triggering event's parameters within your deployment's flow run. This allows you to dynamically pass the necessary arguments. Here's a concise approach: 1. Define Triggers: Use Prefect's

prefect.yaml

or the

.serve

and

.deploy

methods to define deployment triggers. You can include a list of triggers on any deployment in a

prefect.yaml

file. 2. Use Jinja Templates: Within your trigger definitions, you can incorporate Jinja templates to extract and pass specific parameters from the upstream deployment to the triggered deployment. 3. Pass Triggers: When deploying, pass the triggers using the

--trigger

arguments, which can be defined as a JSON string or a path to a

.yaml

or

.json

file. For more detailed guidance, you can refer to the Prefect documentation on automations and triggers. If you need further assistance with the syntax or examples, feel free to ask.
