# Development Container Entrypoint

# This script starts all development services when the container starts,
# both with VS Code Dev Containers and with plain podman-compose.
#
# Services started:
#   - Nginx (HTTPS proxy: Vite 5173 -> 443, Bugsink 8000 -> 8443, API 3001)
#   - Bugsink (error tracking) on port 8000
#   - Logstash (log aggregation)
#   - PM2 (process manager) running:
#     - flyer-crawler-api-dev: API server (port 3001)
#     - flyer-crawler-worker-dev: Background job worker
#     - flyer-crawler-vite-dev: Vite frontend dev server (port 5173)
#
# ADR-014: This architecture matches production (PM2 managing processes)
# ADR-050: Logs are written to /var/log/pm2 for Logstash integration
