that's still largely a "container" or "sandbox", using the same kernel features, and some package / provisioning manager

I use Dagger, which is BuildKit based underneath, and aligns closely with Dockerfiles, but is far more flexible and is accessible from many programming languages

so in this sense "it's not my own take", but both of these are our own "take" on assembling several pieces of technology to realize a certain application feature. It's the feature that is the "dime-a-dozen" and most people largely don't care what technologies you choose to deliver that feature
