@Marvin In a deployment, how do I append to a default job variable for a specific run? For example, I have a docker work pool which has a default volume, but I want custom volumes to be included on a per run basis

To append custom volumes to a Docker work pool for a specific run in Prefect, you can override job variables when running flows. This can be done using the Prefect UI, CLI, or through automation actions. Here's a concise guide: 1. Using the Prefect UI: You can pass a dictionary of job variables in the custom run form. This allows you to include custom volumes for that specific run. 2. Using the CLI: You can specify job variables with the

-jv

or

--job-variable

flag to include custom volumes. 3. Automations: Automations can also use job variables, including those rendered from Jinja templates, to include custom volumes. For more detailed guidance, you can refer to the Prefect documentation on customizing infrastructure. If you need to start a worker for your Docker work pool, ensure the worker is running and ready to pick up jobs. You can manage this through the Prefect UI under the Workers tab. For further details on Docker work pools, visit the Prefect documentation on Docker infrastructure examples.
