# Full CGC plugin stack — self-contained for local development and manual testing.
#
# Includes: Neo4j + CGC core + OTEL collector + OTEL processor.
# Add Xdebug listener with: -f docker-compose.dev.yml
#
# Quick start:
#   cp .env.example .env          # edit NEO4J_PASSWORD at minimum
#   docker compose -f docker-compose.plugin-stack.yml up -d
#   docker compose -f docker-compose.plugin-stack.yml logs -f
#
# With Xdebug (dev):
#   docker compose -f docker-compose.plugin-stack.yml -f docker-compose.dev.yml up -d
#
# Verify:
#   docker compose -f docker-compose.plugin-stack.yml ps
#   curl -s http://localhost:7474              # Neo4j Browser
#   grpcurl -plaintext localhost:4317 list    # OTEL gRPC endpoint (needs grpcurl)
