# syntax=docker/dockerfile:1.7
# karmic-kraken (local-inference-lab vLLM fork, dev/karmic-kraken) — GB10/Spark build.
#
# Clone-at-pin build, NO staged tarballs: the Dockerfile clones every source
# at the pins in versions.env and gates each one (HEAD commit + tree hash).
# A fresh clone of this repo + `bash build.sh` reproduces this image end to
# end. Current tip: vLLM 636afde9 (2026-10-08), which takes B12X from
# FlashInfer 0.7.1 (the standalone b12x repo is archived — no separate wheel).
#
# Runtime: CUDA 13.4.2 devel aarch64 base + torch 2.13.0 cu130 + flashinfer
# 0.7.1 (carries B12X as flashinfer/experimental/b12x + the top-level `b12x`
# import package). GB10 sm_121 fixes baked in (patch_cuda_sm12x.py, eugr
# patch set).
#
# Build: cd docker-images/karmic-kraken && TAG=... bash build.sh
