# OpenStudio Development Configuration
# ⚠️  Copy this file to .env and replace ALL 'changeme' values with strong, unique passwords
#     before running in any environment — especially production.

# Development Mode
# - docker: Run all services in Docker (recommended for most users)
# - local: Run signaling server locally with hot reload (for core development)
DEV_MODE=docker

# Local Development Port (only used when DEV_MODE=local)
# Note: Docker mode always uses port 6736
LOCAL_SIGNALING_PORT=6736

# Icecast credentials — CHANGE THESE before deployment
ICECAST_SOURCE_PASSWORD=changeme
ICECAST_ADMIN_PASSWORD=changeme

# TURN server — CHANGE THIS before deployment
COTURN_PASSWORD=changeme

# Icecast connection (server-side)
#
# ICECAST_HOST / ICECAST_PORT tell the signaling server where to reach Icecast
# for two things: (a) streaming source connection, (b) the public /stream/*
# listener proxy. They must point to wherever Icecast actually listens.
#
#   - docker-compose dev: localhost:6737 (default — Icecast container maps to 6737)
#   - system Icecast (apt install icecast2): localhost:8000 (Debian/Ubuntu default)
#   - reverse-proxied behind Caddy/nginx: still the local Icecast — Caddy fronts the
#     signaling server, which in turn proxies /stream/* to ICECAST_HOST:ICECAST_PORT
#
# Mismatch → /stream/* returns 502 Bad Gateway.
# PUBLIC_DOMAIN is your public hostname. Only deploy/docker-compose.prod.yml
# uses it, to set the Icecast stream directory hostname.
PUBLIC_DOMAIN=studio.example.com
