# Dockerfile for release builds - uses pre-compiled binaries
# This Dockerfile is optimized for CI/CD pipelines where binaries are pre-compiled
# using cross-rs for cross-platform builds, avoiding slow QEMU emulation.
#
# Uses scratch (empty) base image since musl binary is fully statically linked.
# CA certificates are copied from alpine for HTTPS support.
# Stage 1: Get CA certificates from alpine
FROM alpine:latest AS certs
RUN apk add --no-cache ca-certificates
# Stage 2: Final minimal image
FROM scratch
# ARG must be declared after FROM in multi-stage builds
ARG TARGETARCH
ARG TARGETVARIANT
# Copy CA certificates for HTTPS requests to docs.rs and crates.io
COPY --from=certs /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/

# The binary is expected to be at ./binaries/crates-docs-${TARGETARCH}
# TARGETARCH values: amd64, arm64 (set automatically by docker buildx)
