 OpenCat for Team的开源实现

+## docker-compose

+```
+version: '3.7'
+services: 
+  opencatd:
+    image: mirrors2/opencatd-open
+    container_name: opencatd-open 
+    restart: unless-stopped
+    ports:
+      - 80:80
+    volumes:

+
+## Q&A
+关于证书?
+- docker部署会白白占用掉VPS的80，443很不河里,建议用Nginx/Caddy/Traefik等反代并自动管理HTTPS证书.
+
+没有服务器?  
+- 可以白嫖一些免费的容器托管服务:如:koyeb 或者其他
