summary
An interactive debugger for Dockerfiles that embeds BuildKit and hooks LLB ops to provide breakpoints, source-level inspection and the ability to spawn an interactive shell at any instruction, reproducing that instruction’s root filesystem and execution environment. It lets users supply a debugger image (so tools work on scratch/busybox), reuses BuildKit cache to speed iterations, integrates with IDEs via the Debug Adapter Protocol (VS Code, Neovim, Emacs) and runs rootless via rootlesskit.
