# docker-compose.override.lite.yml
#
# Docker Compose override file for "lite" configuration (resource-constrained environments).
# This file extends docker-compose.yml with reduced resource limits and replica counts.
#
# Usage:
# docker compose -f docker-compose.yml -f docker-compose.override.lite.yml up -d
# docker compose -f docker-compose.yml -f docker-compose.override.lite.yml down
#
# Makefile integration:
# make compose-lite-up # Applies this override
# make compose-lite-down # Applies this override
#
# Key differences from base docker-compose.yml:
# - Gateway: 2 replicas (vs 3), reduced CPU/memory
# - Nginx: Reduced CPU/memory limits
# - Postgres: Reduced CPU/memory limits
# - Redis: Reduced CPU/memory limits
# - Monitoring: Uses "monitoring-lite" profile with reduced resources
