Dockerfile.cpu

# This vLLM Dockerfile is used to build images that can run vLLM on both x86_64 and arm64 CPU platforms.
#
# Supported platforms:
#   - linux/amd64 (x86_64)
#   - linux/arm64 (aarch64)
#
# Use the `--platform` option with `docker buildx build` to specify the target architecture, e.g.:
#   docker buildx build --platform=linux/arm64 -f docker/Dockerfile.cpu .
#
# Build targets:
#   vllm-openai (default): used for serving deployment
#   vllm-test: used for CI tests
#   vllm-dev: used for development
#
# Build arguments:
#   PYTHON_VERSION=3.13|3.12 (default)|3.11|3.10
#   VLLM_CPU_DISABLE_AVX512=false (default)|true
#   VLLM_CPU_AVX2=false (default)|true (for cross-compilation)
#   VLLM_CPU_AVX512=false (default)|true (for cross-compilation)
#   VLLM_CPU_AVX512BF16=false (default)|true (for cross-compilation)
#   VLLM_CPU_AVX512VNNI=false (default)|true (for cross-compilation)
#   VLLM_CPU_AMXBF16=false (default)|true (for cross-compilation)
