# Kamado Pool StartOS package image.
#
# Clones the KamadoPool repo at a pinned SHA, then inlines the ckpool,
# ui, and api build stages (mirroring ckpool/Dockerfile and api/Dockerfile
# in the upstream repo). Final runtime image has both binaries plus the
# StartOS entrypoint that supervises them.
#
# TODO: set KAMADO_SHA to a real pushed commit before running `make`.
# The placeholder below is a valid 40-char hex string to keep tooling
# happy but the clone checkout will fail until this is updated.
