New 'tls' union config (disabled by default) spins up an
stunnel4 process inside the container that terminates TLS on
a configurable port (3334 by default) and forwards decrypted
stratum traffic to 127.0.0.1:${STRATUM_PORT}.
Cert is self-signed, generated once on first start with a
10-year validity and persisted at /root/.kamado/tls/ so the
fingerprint stays stable across restarts. SHA-256 fingerprint
is printed to container logs on each startup so users can
pin it on their miners. Miners must connect with
verification disabled (no CA trust chain for a private pool).
Runtime image grows by ~3MB for stunnel4 + openssl. The
supervisor loop now waits on three PIDs and tears all of them
down together if any one exits.
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.
