Suppose I have a flow. In the flow, I want to run a task which is delivered to me as a container. Is there an easy way to have a task simply be “run this container with these arguments”, analogous to

docker run --rm --mount type=bind,source=$SRC,target=$DEST -it thing:label arg1 arg2 …

? My gut feeling is that the

DockerContainer

block should support this but I’m getting a feeling it is for another purpose than this, since I don’t see how to pass the arguments or mess around with the mounts

hi @Daniel Lyons - you should be able to use

DockerContainer

for this

In [6]: from prefect.infrastructure.container import DockerContainer
   ...:
   ...: DockerContainer(
   ...:     image="alpine:latest",
   ...:     command=["echo", "Arguments received:", "arg1", "arg2"]
   ...: ).run()

where

DockerContainer

should also accept `volumes`

will it also accept

mount

?
