Hi there! I’m looking at transitioning to Prefect 2.0 and trying to wrap my head around some of the new stuff. In my existing workflow, I construct a flow programmatically by walking a set of yaml files. This has the effect of needing the

add_task

method from the

flow

class. I don’t think the new API has this. Is there a way to iteratively add tasks to a flow?

Hey Kevin could you provide some more context for what you're trying to achieve by "adding" tasks to the flow, generally speaking if you just need to loop through files and perform the same or similar actions on them you should just be able to write a for loop to do so from a single task

hi @Mason Menges - sure! We allow users in our organization to add entries to a set of yaml files in a directory. Each entry defines a job with the job name, resource requirements (cpu/mem), the docker image they should run out of, an entrypoint, and crucially any other jobs it might depend on upstream. Each job launches a batch run in our docker orchestration tool (

nomad

- it’s a lot like

kubernetes

) and polls the api until the job either times out, fails, or completes successfully. I load these yaml files into a single dictionary, loop through them once to add them to a flow, and then loop through them again to set dependencies. What I’m left with is a single flow with a few different subtrees. I then register the flow with the prefect api and run them on a schedule.
