# =============================================================================
# API Gateway (Kong) - Environment Configuration
# =============================================================================
# This file contains all environment variables needed for Kong API Gateway.
#
# Setup Instructions:
#   1. Copy this file: cp .env.example .env
#   2. Update values according to your deployment environment
#   3. Start services: ./deploy.sh up
#
# IMPORTANT: In production, change all default passwords and secrets!
# =============================================================================

# =============================================================================
# Kong Database Configuration
# =============================================================================
# PostgreSQL password for Kong database
# NOTE: Kong uses hardcoded database username 'kong' and database name 'kong'
#       Only the password is configurable via this variable
# SECURITY: Change this in production!
# Example command to generate: openssl rand -base64 32
KONG_PG_PASSWORD=kong_password

# =============================================================================
# Kong Admin GUI Configuration
# =============================================================================
# Admin GUI URL - Update to match your deployment domain
# Examples:
#   Development: http://localhost:8002
#   Production:  https://admin.yourdomain.com
KONG_ADMIN_GUI_URL=http://localhost:8002

# =============================================================================
# Monitoring Stack Configuration (Optional)
# =============================================================================
# Grafana Admin Password
# SECURITY: Change this in production!
# Example command to generate: openssl rand -base64 24
GRAFANA_ADMIN_PASSWORD=admin123

# Grafana Root URL - CRITICAL: Must match the actual URL users access Grafana from
# IMPORTANT: This affects CORS, redirects, and authentication!
# Examples:
#   Local development:           http://localhost:3030
#   Production with Nginx+SSL:   https://monitor.szaiai.com
#   Production without SSL:      http://monitor.szaiai.com
#
# If you use install-monitor.sh with domain "monitor.szaiai.com", set:
#   GRAFANA_ROOT_URL=https://monitor.szaiai.com
#
# Common mistake: Setting localhost when accessing via domain causes "origin not allowed" error!
# After changing this value, you MUST restart monitoring services:
#   ./deploy.sh monitoring down && ./deploy.sh monitoring up
GRAFANA_ROOT_URL=http://localhost:3030

# Docker network name for monitoring services
# Note: This should match the network created by docker-compose.yml
NETWORK_NAME=api-gateway_rwa-network

# =============================================================================
# Backend Services Configuration
# =============================================================================
# Backend server IP address for connectivity checks
# IMPORTANT: Update this to the actual IP where your microservices are deployed!
# You MUST also update service URLs in kong.yml to match this IP
# Examples:
#   Local development: 127.0.0.1
#   Remote server:     192.168.1.111
#   Same server:       127.0.0.1
#
# Default is example IP - CHANGE THIS to your actual backend server IP!
# If backend is on same server as Kong, use 127.0.0.1
BACKEND_SERVER_IP=192.168.1.111
