你的报错是：
php_network_getaddresses: getaddrinfo failed
百度搜搜：https://blog.csdn.net/ownfire/article/details/7850890
网络加载问题。
php_network_getaddresses: getaddrinfo failed: Name or service not known https://packagist.phpcomposer.com could not be fully loaded
你用的是composer的中国镜像把？ 不知道是不是中国镜像挂了，还是怎么情况，
你可以切换成国外镜像试试：
http://www.fancyecommerce.com/2017/04/19/composer-默认地址改为中国镜像地址，以及中国镜像地址/
要么你就先用百度网盘的地址， https://github.com/fecshop/yii2_fecshop_docker
往下看，会看到百度网盘的地址，里面是完整文件压缩包
