This Post will give you an introduction to Docker BuildKit & Buildx What is buildkit? Buildkit is a project made by moby it’s working on top of docker to give you ability to have custom volumes while building images (caching, secret, etc.) Using buildkit you cat easily cache package managers (even if you change packages), change network mode per-layer, secret files only for one layer, ssh keys (cloning a repo), or running one layer as privileged, and also faster than normal docker :)
