# 负载均衡配置

sdocker-compose 部署其他服务时，需指定 labels

下面以微服务举例：

假如有两个微服务，端口号分别为 1001，1002。

user 服务对应 1001 端口，video 服务对应 1002 端口。

	version: "3"

	services:
	user-service:
	image: your/user-service-image
	labels:
	- "traefik.http.routers.user-service.entrypoints=http"
	- "traefik.http.routers.user-service.rule=Host(`domain.com`) && PathPrefix(`/user/`)"
	- "traefik.http.services.user-service.loadbalancer.server.port=1001"

	video-service:
	image: your/video-service-image
	labels:
	- "traefik.http.routers.video-service.entrypoints=http"
	- "traefik.http.routers.video-service.rule=Host(`domain.com`) && PathPrefix(`/video/`)"
	- "traefik.http.services.video-service.loadbalancer.server.port=1002"
