# MeshCore Hub - Environment Configuration
# Copy this file to .env and customize values
#
# Configuration is grouped by service. Most deployments only need:
# - Common Settings (always required)
# - MQTT Settings (always required)
# - Packet Capture Settings (for observer nodes)
#
# The Collector, API, and Web services typically run as a combined "core"
# profile and share the same data directory.
#
# -----------------------------------------------------------------------------
# QUICK START: Observer Node
# -----------------------------------------------------------------------------
# For an observer node capturing mesh traffic, you need:
#
#   MQTT_HOST=your-mqtt-broker.example.com
#   MQTT_PORT=1883
#   MQTT_USERNAME=your_username
#   MQTT_PASSWORD=your_password
#   MQTT_TLS=false
#   SERIAL_PORT=/dev/ttyUSB0
#
# Serial ports are typically /dev/ttyUSB[0-9] or /dev/ttyACM[0-9] on Linux.
# -----------------------------------------------------------------------------
# -----------------------------------------------------------------------------

# =============================================================================
# COMMON SETTINGS
# =============================================================================
# These settings apply to all services

# Docker Compose project name
# Used as a prefix for container names (e.g., hub-api) and volume names
# (e.g., hub_data). Change per instance when running multiple deployments
# on the same Docker host (e.g., hub-prod, hub-beta, hub-stg).
# For multi-instance setups, see the "Multi-Instance Deployment" section in README.md.
COMPOSE_PROJECT_NAME=hub

# Domain name for this instance (only needed for Traefik deployments)
# Used by docker-compose.traefik.yml to configure routing rules
# TRAEFIK_DOMAIN=meshcore.example.com

# Router priority for Traefik (higher = matched first)
# Use a higher value for more specific subdomain instances to avoid
# conflicts with wildcard routes from other instances on the same host.
#   Production:  10 (default)
#   Staging:     20
#   MQTT broker: 30
# TRAEFIK_PRIORITY=10

# Docker image version tag to use
# Options: latest, main, v1.0.0, etc.
IMAGE_VERSION=latest

# Logging level (DEBUG, INFO, WARNING, ERROR, CRITICAL)
LOG_LEVEL=INFO

# Base directory for runtime data (database, etc.)
# Default: ./data (relative to docker-compose.yml location)
# Inside containers this is mapped to /data
#
# Structure:
#   ${DATA_HOME}/
#   └── collector/
#       └── meshcore.db    # SQLite database
DATA_HOME=./data

# Directory containing seed data files for import
# Default: ./seed (relative to docker-compose.yml location)
# Inside containers this is mapped to /seed
#
# Structure:
#   ${SEED_HOME}/
#   └── node_tags.yaml    # Node tags for import
SEED_HOME=./seed

# =============================================================================
# MQTT SETTINGS
# =============================================================================
# MQTT broker connection settings for collector and API services
# Uses the MeshCore MQTT broker (WebSocket transport with subscriber auth)
# See: https://github.com/michaelhart/meshcore-mqtt-broker

# When using an external broker, set the hostname/IP
# For native (non-Docker) installs, use "localhost" (the Python default)
