我试图创build一个Apache + PHPdocker容器，但我得到一个生成错误。
这是我的dockerfile，

CMD ["/usr/sbin/apache2", "-D", "FOREGROUND"] 这是构build输出，

最后，这是错误信息
The command [/bin/sh -c apt-get update] returned a non-zero code: 100
我已经尝试了几个解决scheme来解决这个问题，他们都没有为我工作。
例如，
Docker容器无法parsingUbuntu 14.04桌面主机上的DNS
命令[/ bin / sh -c apt-get update]返回一个非零的代码：100
谁能帮我这个？ 提前致谢。
您的问题与防火墙设置有关。 以root用户身份执行：
sudo iptables -L -n -v
列出所有防火墙规则并检查FORWARD链策略。 必须设置为接受Docker DNSparsing才能正常工作。
如果设置为DROP或REJECT，则执行：
sudo ufw disable
如果你没有安装ufw，那么执行：
sudo iptables -X sudo iptables -t nat -F sudo iptables -t nat -X sudo iptables -t mangle -F sudo iptables -t mangle -X sudo iptables -P INPUT ACCEPT sudo iptables -P FORWARD ACCEPT sudo iptables -P OUTPUT ACCEPT
