#
# Self-hosted LiveSync WebPeer — Docker image
# Browser-based P2P peer daemon served by nginx.
#
# Build (from the repository root):
# docker build -f src/apps/webpeer/Dockerfile -t livesync-webpeer .
#
# Run:
# docker run --rm -p 8081:80 livesync-webpeer
# Then open http://localhost:8081/ in any modern browser.
#
# What is WebPeer?
# WebPeer acts as a pseudo P2P peer that runs entirely in the browser.
# It can replace a CouchDB remote server by replying to sync requests from
# other Self-hosted LiveSync instances over the WebRTC P2P channel.
#
# P2P (WebRTC) networking notes
# ─────────────────────────────
# WebRTC connections are initiated by the *browser* visiting this page, not by
# the nginx container itself. Therefore the Docker network mode of this
# container has NO effect on WebRTC connectivity.
# Simply publish port 80 (as above) and the browser handles all ICE/STUN/TURN
# negotiation on its own.
#
# If the browser is running inside another container or a restricted network,
# configuring a TURN server in the WebPeer settings is recommended.
