# Production pool server: builds native deps then runs the mining pool.
# Requires Redis and MySQL at runtime (see docker-compose or env config).
#
# Build context must be the parent directory (zano-upstream/), e.g.:
#   docker build -f zano-nodejs-pool/Dockerfile -t lethean-pool .
#
# Runtime env:
#   REDIS_HOST, REDIS_PORT  — Redis connection
#   MYSQL_HOST, MYSQL_USER, MYSQL_PASS, MYSQL_DB  — MySQL connection
#   (or mount a config.json over /app/config.json)
