Not in my experience. Any concrete examples off the top of your head, where it's more work than setting up pipes in python manually?

Fill in the blank to run a docker container which opens the file with user-provided path in (say) vim.

docker run --rm -it ...?

Now run a container doing the exact same thing ("docker-in-docker").

docker run --rm -it -v $DOCKER_HOST:/var/run/docker.sock ...?

    Never used docker before, but this seems to work:

        docker run --rm -it debian bash -c 'vim -- "$1"' _ "$user_provided_path"

      Looks relatively safe to me, though it doesn't seem to work because debian:latest doesn't have vim in it (so I'm skeptical of your implicit claim of having tried it), and, if $user_provided_path is empty, it defaults to browsing the filesystem. But there are a lot of characters there that are specifically there to avoid footguns; without them, it would seem to work, but it would fail when $user_provided_path contained special characters.

      The version I tested was

          docker run --rm -it debian bash -c 'apt update; apt install -y vim; vim -- "$1"' _ "$user_provided_path"
