# Multi-stage build para axon-server (Rust)
#
# §Fase 12.a — `axon-rs` consume `axon-frontend` vía path dep
# (`../axon-frontend`), por lo que el build context de Docker debe
# ser la raíz del monorepo, no `axon-rs/`. Invocar desde el root:
#
# docker build -f axon-rs/Dockerfile -t axon-server:1.4.x .
#
# Builder uses rust:latest because aws-sdk-secretsmanager (M3) and time-core
# pull in MSRVs ≥ 1.91.1 — too recent to pin to a specific image tag without
# a rust-toolchain.toml. Add a rust-toolchain.toml to lock the compiler version
# once the MSRV stabilizes across all deps.
#
# Runtime is ubuntu:24.04 (noble, glibc 2.39) to match what rust:latest links
# against. debian:bookworm-slim only ships glibc 2.36 which causes startup failures.
# Stage 1: Builder
# hadolint ignore=DL3007
