The gateway Dockerfile hardcoded the linux_x64 gitleaks download, so an image built on/for aarch64 (Apple Silicon) baked in an x86_64 binary. It sat quiet until the git-gate pre-receive hook first invoked it, where the kernel refused the foreign-arch exec — `gitleaks: Exec format error` — failing every push through that gateway. Pick the asset + pinned SHA from the build's target architecture: TARGETARCH (auto-populated by BuildKit) with a `dpkg --print-architecture` fallback for a legacy builder, and hard-fail on any unsupported arch. Each arch keeps its own SHA256 verification, so no supply-chain regression. The existing integration test test_gateway_image.py:: test_gitleaks_binary_present_and_versioned execs `gitleaks version` in the built image, so it now passes on arm64 instead of hitting the same error.

# Gateway data-plane image (PRD 0024 bundle shape; PRD 0070 gateway).

#
|
|
# The egress / git-gate / supervise *data plane* — one image, run by
|
|
# the consolidated per-host gateway (PRD 0070). It is NOT the
|
|
# orchestrator control plane: that is the separate, lean
|
|
# `bot-bottle-orchestrator` image (Dockerfile.orchestrator, #384), which
|
|
# ships only python + the stdlib-only `bot_bottle` package and none of
|
|
# this image's mitmproxy / git / gitleaks payload.
|
|
#
|
|
# Collapses the prior per-daemon images (egress, git-gate,
|
|
# supervise) into one. A small stdlib-Python init supervisor at
|
|
# /app/gateway_init.py spawns all daemons, forwards SIGTERM, and
|
|
# propagates per-daemon stdout/stderr to the container log with a
|
|
# `[name]` prefix. See PRD 0024 for the rationale.
