looking for help with this.. - but - conceptually, I want to build an ETL pipeline that is a series of deployments? based on the completion of the previous deployment. 1) is this the right architecture for prefect? 2) how do i trigger a deployment to run from the completion of a deployment in prefect? (CLI) not cloud.

You can run and await a deployment in python with

prefect.deployments.run_deployment

, so you can build a DAG there easily enough. You can pass data to downstream deployments by returning a PersistedResult or by writing to a shared a file/bucket path.
