# --- Builder stage ---
# Chainguard exception (workspace CLAUDE.md §9): the build stage stays on the
# upstream `rust` image because the workspace pins its toolchain via
# rust-toolchain.toml (channel 1.88.0) and needs rustup to honour that pin;
# cgr.dev/chainguard/rust free tier is :latest-only (floating toolchain), which
# would silently drift the compiler under a pinned, reproducible release build.

# Git sha for `corecruxd --version` / the boot banner. The build context does

# Release version: the v2 console reports the version at runtime (via the daemon
# API), so no build-time HTML stamping is needed. RELEASE_VERSION is retained as

# Chainguard wolfi-base (CLAUDE.md §9): rebuilt daily, zero-known-CVE target,
# minimal package set. Free tier requires the :latest tag (accepted).
FROM cgr.dev/chainguard/wolfi-base:latest

# Runtime packages:
# - ca-certificates: TLS trust for optional *opt-in* outbound features (sync,
#   remote embedding endpoints). The daemon dials nothing by default — see
#   scripts/assert-no-phone-home.sh.
# - curl: container HEALTHCHECK probe.
# - git: the update-posture probe (update.rs) shells out to `git fetch`/
#   `git rev-list` against the /repo bind mount on repo-checkout deploys to
#   compute ahead/behind. Without git the fetch silently fails and the banner
#   reports a confidently-wrong drift count from the stale cached tracking ref.
