I am new to Docker and am trying to cut corners in building Docker images. I heard that Coiled could be used to generate Docker images from Conda environment yamls. I have done this, but now I would like to be able to go from this image to a Docker file.

I use the code snippet from this post to generate a Dockerfile from the image.

sudo docker history [image_id_or_name] --no-trunc $argv  | tac | tr -s ' ' | cut -d " " -f 5- | sed 's,^/bin/sh -c #(nop) ,,g' | sed 's,^/bin/sh -c,RUN,g' | sed 's, && ,\n  & ,g' | sed 's,\s*[0-9]*[\.]*[0-9]*[kMG]*B\s*$,,g' | head -n -1

I get this result. So my question is, can this be used with docker build to rebuild the image, or does the fact that this image was made with Coiled mean this is not possible?

    It's almost doable, but the first statement (ADD) and the 8th from the bottom (COPY) are the statements that were used, but they copied files from the host that you might not have. The ADD is the one that was used to created the base OS image. The COPY statement is probably the app source code that you might have access to. – Hans Kilian May 03 '22 at 17:01
  • Thank you for the quick response. I suspected as much from the COPY statement and I do have access to that file. Can the ADD statement be substituted from something like `FROM nvidia/cuda:10.2-base-ubuntu18.04`? To my understanding all it is doing to define the OS to use. – Noah_Seagull May 03 '22 at 17:13
  • The base image is something basic, like `debian` or `ubuntu`. The nvidia/cuda image adds a lot of stuff that would show up in the history. As you can see here, the ubuntu Dockerfile matches the first 2 statements well: https://github.com/tianon/docker-brew-ubuntu-core/blob/5ed9ebdc8e9050d5b327c7ce3cda08b62cd28f67/bionic/Dockerfile. For comparison, this is nvidia/cuda: https://gitlab.com/nvidia/container-images/cuda/blob/master/dist/11.6.0/ubuntu1804/base/Dockerfile – Hans Kilian May 03 '22 at 18:11
