# Compose override: exposes Redis on the host so remote probes can connect via a tunnel.
#
# Enabled automatically by setup.sh when the operator picks a tunnel option.
#
# The bind host is taken from REDIS_BIND_HOST in .env:
#   - 100.x.y.z  — Tailscale IP (recommended; only tailnet peers can reach it)
#   - 127.0.0.1  — localhost only (used with Cloudflare Tunnel / cloudflared running on the host)
#   - 0.0.0.0    — all interfaces (requires strict firewall rules)
#
# Do NOT set REDIS_BIND_HOST to 0.0.0.0 unless you know the host firewall
# blocks port 6379 from the public internet.
