Multi-stage Dockerfile clones KamadoPool at a pinned SHA, builds ckpool and kamado-api (with embedded Svelte UI), runtime image supervises both processes via tini + wait -n. Config covers bitcoind mainnet/testnet4 variant, payout address, coinbase tag, vardiff knobs, and log level. Web UI interface only — stratum :3333 requires a router port-forward or simpleproxy workaround because StartOS 0.3.x does not forward raw TCP on LAN. TODO before first build: pin KAMADO_REPO + KAMADO_SHA in the Dockerfile to a pushed commit.
