Creating dockerfile without docker daemon

[nezygis]

Hello, is it possible to use cog to create a dockerfile which would later be used to build image with kaniko? The problem is that we do not want to use the docker daemon in our builds. Maybe an option to extract the dockerfile before running the docker build?

Hi @nezygis. Yes, you can create a Dockerfile with Cog by running cog debug.

$ cog debug > Dockerfile

@mattt thank you! that works for the dockerfile but when I'm trying to build the image it fails on:
COPY .cog/tmp/build4132123682/cog-0.0.1.dev-py3-none-any.whl /tmp/cog-0.0.1.dev-py3-none-any.whl

.cog/tmp/build.. directory does not exist. is there an additional build step that I need to run?

EDIT: it seems like it is due to the cleanup command being executed. is there any way to avoid it when running debug?
