Prefect 1.0 -> 2.0 Question: Is there a reason that

Deployment.build_from_flow

requires a

.prefectignore

file? Currently have all of those flows in a pip installable python module, would be nice to be able to override that rather than need to skip upload in the build, and then separate calls to

apply()

and

upload_to_storage(...)

.

Prefectignore file is an important concept to guard against uploading code you may not want to get uploaded to remote storage. Of you don't create it, Prefect will generate that for you automatically

Not if you're only using the

build_from_flow

. If you work through the tutorial at https://docs.prefect.io/tutorials/deployments/#deployment-creation-with-python but don't bother doing the CLI - the file doesn't exist in the directory and isn't mentioned as a requirement - the

prefect deployment build

command auto-generates the file where the python api does not.
