# Render Blueprint — deploy NetPulse Live (the real-time BGP anomaly monitor).
#
# To deploy:
#   1. Open https://dashboard.render.com/blueprints
#   2. "New Blueprint Instance" -> connect github.com/pauti04/netpulse
#   3. Render builds the Dockerfile and serves the live monitor on a
#      free .onrender.com subdomain in ~3 minutes.
#
# The `netpulse live` process taps the RIPE RIS Live BGP feed and serves a
# self-refreshing status page at / plus a JSON feed at /live/recent.
#
# Free-tier caveat: a free web service spins down after 15 min idle (so
# monitoring pauses when nobody's watching, and cold-starts in ~30s). For
# true always-on 24/7 monitoring, use Render's Starter plan or Fly.io with
# a payment method — change `plan: free` below to `plan: starter`.
