Go 1.22 module that polls CKPool's Unix socket control API, queries
Bitcoin Core over JSON-RPC, merges both into a thread-safe snapshot, and
serves it over REST. Layout:
api/
├── cmd/kamado-api/main.go signal-aware entrypoint
└── internal/
├── config/ env var loader with validation
├── ckpool/ socket client (4-byte LE length-prefixed wire
│ protocol verified against libckpool.c), typed
│ response models for poolstats/users/workers/
│ clients/uptime, + unit tests using a fake
│ unix socket server
├── bitcoind/ minimal JSON-RPC client, getblockchaininfo
│ and getnetworkhashps
├── state/ Aggregator that refreshes a merged Snapshot
│ on a ticker; readers get a copy under RWMutex
└── httpapi/ REST handlers on Go 1.22 ServeMux:
/api/health /api/pool /api/users
/api/workers /api/clients /api/snapshot
CKPool stores hashrate as "dsps" (diff shares per second); we convert
to H/s via the 2^32 constant used by GoBrrr-Pool and other clients.
Every stat CKPool exposes to its socket API is surfaced — useragent,
IP, per-client diff, per-worker best diff — closing the gap against
Bassin which only reads the 60-second stats files.
Dockerfile does a CGO_ENABLED=0 static build on golang:1.22-bookworm
with -trimpath -ldflags=-s -w. docker-compose now runs both ckpool and
kamado-api, sharing a named volume for /run/ckpool so the API can
dial the stratifier socket directly.
Deferred to Phase 2b (called out in README):
- Bitcoin Core ZMQ hashblock subscriber
- WebSocket push for real-time UI updates
- SQLite persistence (block history, best-share history)
- CKPool log tailer for "Solved and confirmed block" detection
Tests and build NOT run in this commit — Go isn't installed in the
dev environment. Run `make api-test` or `make api` to verify.
