#
# Pre-built builder base image for LocalAI's C++ backends.
#
# This Dockerfile is the source of truth for the
# `quay.io/go-skynet/ci-cache:base-grpc-*` images that
# `.github/workflows/base-images.yml` builds and pushes. The output of a
# build is a fully-prepped builder layer containing:
#
# - apt build deps (build-essential, ccache, git, make, pkg-config,
# libcurl4-openssl-dev, libssl-dev, curl, unzip, wget, ca-certificates)
# - cmake (apt or, when CMAKE_FROM_SOURCE=true, compiled from
# ${CMAKE_VERSION})
# - protoc v27.1 at /usr/local/bin/protoc
# - gRPC ${GRPC_VERSION} compiled and installed at /opt/grpc
# - Conditional CUDA toolkit (BUILD_TYPE=cublas|l4t, SKIP_DRIVERS=false)
# including the cuda-13 + arm64 cudss/nvpl special case
# - Conditional ROCm/HIP build deps (BUILD_TYPE=hipblas)
# - Conditional Vulkan SDK 1.4.335.0 (BUILD_TYPE=vulkan)
#
# Variants built by the workflow (matrix in base-images.yml):
#
# base-grpc-amd64 ubuntu:24.04, CPU-only
# base-grpc-arm64 ubuntu:24.04, CPU-only
# base-grpc-cuda-12-amd64 ubuntu:24.04 + CUDA 12.8
# base-grpc-cuda-13-amd64 ubuntu:22.04 + CUDA 13.0
# base-grpc-cuda-13-arm64 ubuntu:24.04 + CUDA 13.0 (sbsa)
# base-grpc-l4t-cuda-12-arm64 ubuntu:22.04 + CUDA 12.x (legacy JetPack)
# base-grpc-rocm-amd64 rocm/dev-ubuntu-24.04:7.2.1 + hipblas
# base-grpc-vulkan-amd64 ubuntu:24.04 + Vulkan SDK 1.4.335
# base-grpc-vulkan-arm64 ubuntu:24.04 + Vulkan SDK ARM 1.4.335
# base-grpc-intel-amd64 intel/oneapi-basekit:2025.3.2 (sycl)
#
# This is a SINGLE-stage Dockerfile by design: the final image IS the
# builder base. The intermediate gRPC compile happens inside this same
# stage so consumer Dockerfiles in PR 2 can simply
# `FROM quay.io/go-skynet/ci-cache:base-grpc-<variant>` without needing a
# COPY --from=grpc step. /opt/grpc is the canonical install prefix and
# downstream builds will add it to CMAKE_PREFIX_PATH (or copy to
# /usr/local) the same way Dockerfile.llama-cpp does today.
#
# Install logic lives in .docker/install-base-deps.sh, which is also
# bind-mounted by the variant Dockerfiles' builder-fromsource stage.
# This guarantees bit-equivalence between the prebuilt CI base and the
# from-source local-dev path — both invoke the same script with the
# same env inputs.
