# syntax=docker/dockerfile:1.7
# Pool-Stack Docker Compose Dev Build
#
# Builds the BlockDAG node + nodeworker, mining-pool,
# and the cpu-miner from LOCAL CLONES of the source repositories.
# Build inputs are provided as named BuildKit contexts from compose:
#
#   stack_src          -> stack-redis repo root
#   blockdag_corechain -> local clone of blockdag node source
#   pool_src           -> local clone of mining pool source
#   cpu_miner_src      -> local clone of cpu miner source
#   dashboard_src      -> local clone of redis-dash source
#
# Optional snapshot import: SNAPSHOT_PATH copies a .bdsnap from the build context
# (see compose / Makefile). No URL download. Datadir matches node.conf.
