# ----------------------------------------------------------------------------
# Kamado Pool — development compose
#
# Spins up ckpool-solo and kamado-api pointing at a bitcoind. Expects
# bitcoind to be reachable at the host/port set in the env blocks below.
# For local testing, run bitcoind on regtest/testnet4 and set these via .env.
#
# ckpool and kamado-api share the `ckpool-sock` named volume so the API
# can dial /run/ckpool/stratifier directly.
