    # 容器內使用pm2-runtime，而不是pm2，參考https://stackoverflow.com/questions/55936473/docker-exits-with-code-0-when-using-pm2-start

    networks:
      my_net:

pm2啟動命令pm2-runtime

這裡注意容器內使用pm2-runtime，不能用pm2，否則報

Docker exits with code 0 when using pm2 start

原因在於pm2是後臺執行，docker容器不知道pm2應用的啟動，使用pm2-runtime可以進行前端執行，請檢視stackoverflow。
