使用docker-compose实现服务

version: '3.6'
services:
  redis:
    image: redis
  web:
    image: cfanbo/swoole4_php7:v1
    depends_on:
      - redis
    links:
      - redis
    volumes:
      - /Users/sxf/sites/msgserve:/usr/src/myapp
    command: "php src/push_server.php start"

容器环境为soole+php7
容器里的web目录为/usr/src/myapp,通过使用volumes来实现将物理机器上的目录挂载到窗口里,基中 php src/push_server.php start 是用swoole framework来搞的一个服务，需要依赖于redis容器。但 docker-compose up的时候，总是提示

msgserve_web_1 exited with code 0
Killing msgserve_redis_1  ... done

容器状态

CONTAINER ID        IMAGE                    COMMAND                  CREATED                  STATUS                      PORTS               NAMES

20a803504037        redis                    "docker-entrypoint.s…"   19 minutes ago           Up 14 seconds               6379/tcp            msgserve_redis_1

另一个redis容器正常的，看日志是“ Server is already running.”的，这种情况下如何解决?
