ai-dock image runs ComfyUI on port 18188 (10000+8188), not 8188.
Caddy in the image doesn't proxy 8188->18188, so probes and service
must target 18188 directly. This caused 273 startup probe failures
and constant restarts over 45h.
- deployment: containerPort, probes, env all point to 18188
- service: targetPort 18188
- ingress: TLS via letsencrypt, WebSocket upgrade headers for live preview
- CoreDNS: rewrite comfyui.riotpiao.com to nginx controller
