Selection of image build for reproducibility

let's say we want to reproduce a build that happened 6 months earlier. This includes running the same builder that was used originally (eg msbuild version). Is it possible to specify a sha or version of the builder images in the yaml, similar to how one would use container tags?

According to , there's only current and previous. That is not enough for our reproducibility requirements, where the original build environment must also match at the time of reproduction.

    We don't keep older images that are outside the previous-current-preview frame.
    But you can look at private build cloud hybrid solution or AppVeyor server which would allow you to work with your own set of build images.

    Thank you for the confirmation.

    What's the main reason behind why you don't have a history of images?
