rose-ash/docker-compose.dev-sx-host.yml

# host-on-sx live service — the SX web host (lib/host) served by the native
# http-listen server via lib/host/serve.sh. Joins the sx-dev project + externalnet
# so Caddy can reverse_proxy a subdomain to it (blog.rose-ash.com). Isolated from
# the sx_docs server: separate container, separate port.
#
# Usage:
#   docker compose -p sx-dev -f docker-compose.dev-sx-host.yml up -d sx_host
#   docker compose -p sx-dev -f docker-compose.dev-sx-host.yml logs -f sx_host
#   docker compose -p sx-dev -f docker-compose.dev-sx-host.yml down
