If there are too many packages to pin, then I assume there are too many package to audit changes in for each image build you do? If that is true, how do you hav

  I think we're talking about two different things. I'm thinking of pinning packages as say, my npm.lock specifies I will use version 2.2.19 of tailwind css. Or my Dockerfile has redis:6.2.6 as it's base image. Both of those are fully pinned, but nothing stops Tailwind or Redis from uploading new versions of the package and reusing the version number (I believe NPM actually disallows this, Docker hub does not). So my build is not technically reproducible. I can solve this by maintaining my own Docker registry, and my own NPM registry, but that's more work that just fully specifying versions in a configuration file. As for auditing changes, well most people don't. They update their dependencies and run their tests and if the tests pass, ship it! Most companies don't have a team auditing every single dependency that's pulled in, much less every update after a dependency has been approved. They simply trust the authors of Redis not to screw them. It's great if you do, I'm certainly not arguing against it, but it's far from the norm.

    You can reference docker images by their SHA digest which is immutable, e.g.: docker pull redis@sha256:619af14d3a95c30759a1978da1b2ce375504f1af70ff9eea2a8e35febc45d747
