# Kamado Pool StartOS package image.

# Clones KamadoPool at a pinned SHA, builds the patched ckpool-solo
# binary, builds the Go api binary with embedded Svelte UI, then
# assembles a small runtime image that supervises both processes.

# TODO: set KAMADO_REPO + KAMADO_SHA to a pushed commit before
# running `make` — the defaults below are placeholders and the build
# WILL fail until the KamadoPool source repo is pushed to GitHub.
