@Marvin how can I override the task definition of my work pool's base job template on a per-deployment basis? I want to provide a different task definition ARN in each deployment using the Python SDK. Give a code example if you can.

It seems that the provided example does not quite match your request, as it's a general example of defining and running tasks within a flow in Prefect, and not specific to deploying with a customized base job template for AWS ECS task definitions. Customizing the Task Definition on a per-deployment basis can be done when setting up a deployment. You would customize your deployment script for each environment and specify the AWS ECS task definition ARN for that environment. However, to provide an accurate code example, it would help to know which part of the Prefect deployment you're looking at or what the equivalent functionality in Prefect is, especially since you mention you're using Python SDK which suggests you're working with Prefect 2.x - something I'm not familiar with yet. If you are looking to override ECS task definitions within a Prefect Deployment using the Python SDK, the functionality might be incorporated within configuring DeploymentSpecs, Infrastructure specs or similar components in the new version. I'd suggest further examining the documentation or recent changes that might have been made in Prefect 2.x, especially around deployments, infrastructure, and ECS. For a specific code example, I would need to find more relevant information. Would you like me to continue searching the Prefect documentation or GitHub issues for more related information?
