I've been attempting to move an application to the cloud for a while now and have most of the services set up in pods running in a k8s cluster. The last piece has been giving me trouble, I need to set up an image with an older piece of software that cannot be installed silently. I then attempted in my dockerfile to install its .net dependencies (2005.x86, 2010.x86, 2012.x86, 2015.x86, 2015.x64) and manually transfer a local install of the program but that also did not work.

Is there any way to run through a guided install in a remote windows image or be able to determine all of the file changes made by an installer in order to do them manually?

You can track the changes done by the installer following these steps:

  • start a new container based on your base image 
docker run --name test -d <base_image>
  • open a shell in the new container (I am not familiar with Windows so you might have to adapt the command below)
docker exec -ti test cmd

  • Run whatever commands you need to run inside the container. When you are done exit from the container

  • Examine the changes to the container's filesystem:

docker container diff test

You can also use docker container export to export the container's filesystem as a tar archive, and then docker image import to create an image from that archive.

  • The issue I'm having is installing something into the windows container. The software that must be installed on this image is only available in an attended installer. – Foolish Dave Feb 19 '20 at 20:29
  • My answer solves exactly that problem if you follow the steps. – Mihai Feb 20 '20 at 04:02
  • The installer requires that you utilize the install gui, there are no command line arguments or prompts to run it. – Foolish Dave Feb 20 '20 at 14:19
