# Java Edition Minecraft behind mc-router. Live since 2026-10-06 at mc.gbrown.org.
#
# mc-router owns the one public port (25565) and routes each player by the hostname
# they typed: Java clients send it in their first packet, so several servers can
# share one port and one IP. Bedrock clients do not send it, which is why the
# Bedrock server in ../Bedrock stays separate on its own UDP port.
#
# Start:    docker compose up -d        (from this directory)
#
# Each hostname needs a DNS-only (grey cloud) A record in Cloudflare pointing at the
# home IP. The proxied *.gbrown.org wildcard can't carry Minecraft traffic, and a
# specific record overrides it. UniFi forwards 25565/tcp to this host. Home
# Assistant's Cloudflare integration keeps these records on the current home IP;
# select each new record there too.
#
# Add a server:
#   1. mkdir servers/<name>, then copy the "gib" service below and point it there
#   2. add "<hostname>=<service>:25565" to MAPPING
#   3. add the DNS-only record for <hostname>
# Servers publish no ports of their own; only mc-router is reachable from outside.
