I want to generate/get a Dockerfile for an image that is pushed to registry, one that I don't have locally, without docker pull that image. I know it's possible to do this with docker CLI if the image already exists locally.

    I don't think this is possible, even when the image exists locally. How would you do that? – Henry Nov 20 '20 at 05:40

  • You can create a tar ball and can load it – Ashok Nov 20 '20 at 09:00
  • I think you cannot generate Dockerfile even if you load image locally using tarball. All you can do is use "docker inspect " command to get all info about image. then generate Dockerfile yourself from there. even this method have some limitations – Rezwan Nov 20 '20 at 10:02
