# Ruflo v3.5 — Optimized Production Image
# Multi-stage Alpine build with --omit=optional for <100MB image
#
# Build:
#   docker build -t ruflo:lite -f v3/@claude-flow/cli/docker/Dockerfile .
#
# Run:
#   docker run --rm ruflo:lite ruflo --version
#   docker run --rm ruflo:lite ruflo doctor
#   echo '{"jsonrpc":"2.0","id":1,"method":"initialize"}' | docker run --rm -i ruflo:lite
#
# Size comparison:
#   npx ruflo@latest (cold): ~1.3GB, 914 packages, 35s startup
#   ruflo:lite image:        <100MB, ~60 packages, <5s startup

# --ignore-scripts skips preinstall cache scanning (no-op in CI)

# Prune heavy optional transitive deps that npm still resolves.
# These are all optionalDependencies of @claude-flow/cli — the CLI
# works fine without them (graceful fallbacks built in).
#   agentic-flow: 238MB (ONNX runtimes, OpenTelemetry, Anthropic SDK)
#   @opentelemetry: 135MB (transitive via agentic-flow)
#   onnxruntime-node/web: 158MB (ML inference, not needed for CLI)
#   @anthropic-ai: 72MB (SDK, only needed when calling API directly)
#   @xenova: 45MB (transformers.js, not needed for CLI)
#   agentdb: 37MB (optional memory backend)
#   @ruvector: 28MB (optional neural patterns)
#   ruvector: 9MB (optional intelligence)
#   onnx-proto: 22MB (protobuf for ONNX)
#   tiktoken: 23MB (token counting, optional)
#   @img: 16MB (image processing, not needed)
#   better-sqlite3: 10MB (native, optional — sql.js used instead)
