Containerfile

# Build Linux wheels for context-server (local podman/docker helper).
#
# ORT's prebuilt static libraries need glibc >= ~2.38 (__isoc23_*,
# __libc_single_threaded), so classic manylinux_2_28 images cannot link.
# Ubuntu 24.04 (glibc 2.39) matches that requirement.
#
# GitHub Actions builds wheels natively on ubuntu-24.04 with rust-cache instead
# of this image (see .github/workflows/ci.yml / release.yml).
#
# Local:
#   ./scripts/build-wheel.sh
#   VERSION=2026.716.1 ./scripts/build-wheel.sh
#
# Extract without the helper:
#   podman build --build-arg VERSION=2026.716.1 -t context-server-wheel -f Containerfile .
#   cid=$(podman create context-server-wheel)
#   podman cp "$cid:/out/." ./dist/ && podman rm "$cid"
