Answer 1

感觉像是用完了swap内存，试下

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
/sbin/mkswap /var/swap.1
/sbin/swapon /var/swap.1

具体看下这里

Answer 2

proc_open(): fork failed - Out of memory

内存用完了，fork 不了子进程了。

file could not be downloaded: php_network_getaddresses

无法访问到对应的网络地址，一般是地址访问不通或者本地网络环境有问题

Answer 3

file could not be downloaded: php_network_getaddresses

重启下docker服务, 再试就OK了.
