# Wavelength (waved) Multi-Stage Build
#
# Builds the waved client daemon and wavecli tool from local source.
# The baselib/ submodule must be present since go.mod uses a local replace.
#
# Usage:
#   docker build -t waved:local .
#   docker run waved:local --network=regtest --wallet.type=lnd --lnd.host=lnd:10009
#
# The default build uses the default tag set, which excludes the swap and
# wallet RPC subservers. To get the everyday wallet verbs (balance, send,
# recv, activity, ...) the daemon needs both optional tags:
#
#   docker build --build-arg GOTAGS="wavewalletrpc swapruntime" -t waved:wallet .

# --- Builder ---
FROM golang:1.26.0-alpine AS builder

# Optional Go build tags, taking the same space-separated value as the
# Makefile's tags= parameter (see build-wavewalletrpc). Empty by default so an
# unqualified `docker build` keeps producing the default tag set: no existing
# image silently grows a wallet RPC surface. Note that wavewalletrpc requires
# swapruntime alongside it; the pair is what the daemon checks.
ARG GOTAGS=""
