Is there any facility to pass a `--build-arg` for a Dockerfile to the prefect register CLI command?

Hey @Leon Kozlowski, just got to looking at this and I think you’re right
l
It looks like that should be correct but I’m getting a 
TypeError
Copy code
TypeError: build() got an unexpected keyword argument <MY_ARGUMENT>
I could be wrong on this but, when running the 
docker.APIClient().build(…)
function here I believe they 
build_kwargs
on prefect side should be passed 
buildargs
on the docker side
k
Could you show me how you used it?
l
Copy code
# Building flow storage via `prefect.storage`
flow.storage = Docker(
    dockerfile="Dockerfile",
    env_vars=config.ENVIRONMENT_VARIABLES,
    image_name=config.DOCKER_IMAGE_NAME,
    image_tag=config.DOCKER_IMAGE_TAG,
    registry_url=config.DOCKER_REGISTRY_URL,
    build_kwargs={"MY_ARGUMENT": os.getenv("MY_ARGUMENT")},
)  # pragma: no cover
k
Will give it a shot.
Try
Copy code
flow.storage = Docker(
    build_kwargs={"buildargs":{"MY_ARGUMENT": "YO"}},
)
