Hey all, I am trying to run flows using Docker as infrastructure. I’ve set the pull policy to never because I’m currently performing tests and the image is not public — in other words, I am forcing the agent to use the local ones. So far, so good. The issue arises when running the flow, the container will try to run

python -m prefect.engine flow_uuid

, it fetches the flow but then tries to copy files into the same folder, in this case

deployment.path

is the

cwd

&

pwd

which in turn means that

.

resolves to

deployment.path

— making the

filesystems.LocalFileSystem.get_directory

copy the files into themselves (through

shutil.copytree

) which ends up in a HUGE error like so:

[<redacted for brevity>, '.', 'c', 'f', 'g', "'", '>', ' ', 'a', 'n', 'd', ' ', "'", '.', '/', '.', 'i', 's', 'o', 'r', 't', '.', 'c', 'f', 'g', "'", ' ', 'a', 'r', 'e', ' ', 't', 'h', 'e', ' ', 's', 'a', 'm', 'e', ' ', 'f', 'i', 'l', 'e', '<', 'D', 'i', 'r', 'E', 'n', 't', 'r', 'y', ' ', "'", '.', 'f', 'l', 'a', 'k', 'e', '8', "'", '>', ' ', 'a', 'n', 'd', ' ', "'", '.', '/', '.', 'f', 'l', 'a', 'k', 'e', '8', "'", ' ', 'a', 'r', 'e', ' ', 't', 'h', 'e', ' ', 's', 'a', 'm', 'e', ' ', 'f', 'i', 'l', 'e']

With regards to Prefect’s code, I have a solution, just check if both paths match and don’t copy in that case, but I’d like to get some feedback from the Prefect team before reporting a bug and sending in a fix — i.e. if I am doing something wrong.
