# v2.8 — boocontext sidecar container.
# Multi-stage build: Go shim from golang:1.24-alpine, boocontext MCP aggregator
# from node:20-alpine, then an alpine:3.20 runtime holding both.
#
# The shim spawns boocontext as a child MCP process over stdio NDJSON,
# translating HTTP requests to MCP tools/call.
#
# To stage the fork source for a Docker build:
#   tar -czf codecontext/fork.tar.gz -C /opt/forks/boocontext \
#     --exclude=.git --exclude=node_modules --exclude=dist

# Stage 1: Go shim builder
