# sicabe-host-gateway — SATU port untuk docker-proxy + config-agent.
#
# CATATAN: ini varian LOKAL (build dari ./agent). Untuk DEPLOY dari registry
# (termasuk panel, dengan profile) pakai: deploy/stack/docker-compose.yml
#
# Hanya nginx (gateway) yang membuka port host; docker-socket-proxy dan
# config-agent bersifat internal (expose, tanpa port host). Satu API key
# (GATEWAY_API_KEY) diperiksa nginx, lalu request diarahkan berdasarkan path:
#   /_ping /version /info /events /containers/*   → docker-proxy
#   /healthz /env /dbt /ca /catalog(/<name>)      → config-agent
#
# Lihat: docs/desain-host-gateway-terpadu.md
#
# Cara pakai:
#   GATEWAY_API_KEY='<secret-kuat>' \
#   SICABE_DEPLOY_DIR=/path/ke/sicabe-doc/deploy \
#   AGENT_CA_HOST_PATH=/path/berisi/pem AGENT_CA_FILE=/ca/trino.crt \
#     docker compose up -d
#
# Opsional: AGENT_UID/AGENT_GID (default 1000:1000) — UID/GID yang dipakai
# config-agent saat menulis ke host, supaya file (katalog Trino, data OPA) tetap
# dimiliki user host dan bukan root.
#
# Panel (satu URL untuk proxy & config):
#   SICABE_HOSTS=[{"name":"h1","proxyUrl":"http://<host>:22375",
#                  "apiKey":"<GATEWAY_API_KEY>",
#                  "configUrl":"http://<host>:22375",
#                  "configApiKey":"<GATEWAY_API_KEY>","enabled":true}]
