The Prefect documentation does not specifically provide exact syntax for creating a custom automation trigger to match a flow associated with a specific deployment, but it provides general information about the capabilities of automations. Automations in Prefect can be based on a variety of criteria including work pool status, deployment status, and metric thresholds. Specific to your question, you might want to reference the deployment status as part of the criteria for the automation.
Automations can be set up through the Automations API provided by Prefect, which allows programmatic customization of triggers and actions based on arbitrary events. Since the information provided by the documentation is somewhat high-level, creating a custom automation trigger would involve understanding further details about the Automations API usage.
For detailed syntax and examples, you may need to reference the
Prefect documentation on Automations and
Deployments and Flows. These sections may contain additional specifics on the API endpoints and attributes necessary for creating triggers according to your needs.
If a specific example or syntax is needed and not present in the documentation, you may want to check out the
Prefect GitHub repository for code examples or open an issue requesting more information.
