Docker Build Kit

Docker has a lot of cool tricks that are kind of almost like hit, you know, it's tough to try and involve what they've got now. And so you kind of have to opt in for some of these things in different ways. So we say mount bind and I can bind files that are within my Docker context - which means in inside the folder that I'm doing the build. This effectively lets you add or replace the source files with this build time mount. But even if you may bring in a bunch of stuff with them and then delete them, there still is going to be big data about those layers.
