Lets a smoke-test harness pick its own image tag without racing the default fabro:latest, and points future agent sessions at bin/dev/docker-build.sh so they don't hand-roll a throwaway Dockerfile. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Build a local fabro Docker image from the current working tree.
|
|
#
|
|
# The Docker image uses musl binaries for a small Alpine-based runtime. We
|
|
# compile fabro-cli for the target musl triple inside rust:1-bookworm using
|
|
# cargo-zigbuild (zig as the C compiler + linker). Cargo registry and target
|
|
# dir are cached in named volumes so subsequent runs are incremental.
|
|
#
|
|
# Usage:
|
|
# bin/dev/docker-build.sh # host arch, build image at end
|
|
# bin/dev/docker-build.sh --arch amd64 # force amd64 (uses QEMU on non-amd64 hosts — slow)
|
|
# bin/dev/docker-build.sh --tag fabro:smoke # tag image as fabro:smoke (default: fabro)
|
|
# bin/dev/docker-build.sh --arch arm64 --compile-only
|
|
# # stage binary only; skip `docker build`
|
|
# # (useful for multi-arch buildx verification)
