# The toolchain installer image. It does NOT run the cluster — it installs a toolchain
# onto the host and gets out of the way.
#
# This exists to kill a bootstrap paradox: a plain bash installer needs curl, jq
# and sha256sum to already be present, and a minimal Debian has none of them.
# It carries its own toolchain, so the only host prerequisite is Docker.
#
# Two variants from one file:
#   docker build -f ctrl/Dockerfile.deps --target deps        -t <slug>-deps        .
#   docker build -f ctrl/Dockerfile.deps --target deps-full -t <slug>-deps:full   .
#
# deps-full bakes every pinned binary in at build time. `docker save` it and
# you have the whole installer as one file to carry into an air-gapped network.

FROM debian:trixie-slim AS deps

# ca-certificates + curl: fetch and verify. graphviz + python3: render diagrams
# and validate the arch model, so the host never needs an apt package.
#
# docker-cli, NOT docker.io: we only ever talk to the host's daemon through the
# mounted socket, and under --no-install-recommends the docker.io package ships
# docker-init without the actual `docker` binary.

# The installer is the generated standalone kit, not deps.sh plus the files it
# reads. A kit is one file with its pins frozen in and is proven to run with
# nothing else from rig present — which is exactly what an image needs, and
# `make standalone` keeps it current. Pins are the same in every profile's kit.
