码头工人：如何重新创建码头工人的其他iptables规则？ [英] Docker: How to re-create dockers additional iptables rules?
问题描述
当docker-demon启动时，它会向iptables添加一些规则。
当通过 iptables -F 删除所有规则时，我必须停止并重新启动docker恶魔以重新创建dockers规则。
When the docker-demon starts it adds a couple of rules to iptables.
When all rules are deleted via iptables -F i have to stop and restart the docker demon to re-create dockers rules.
有办法让docker重新添加它的附加规则吗？
Is there a way to have docker re-add it's additional rules?
推荐答案
最好的方法是重新启动您的docker服务，然后它将您的docker规则重新添加到iptables中。 （基于deb： sudo服务docker restart ）
the best way is to restart your docker service, then it'll re-add your docker rules to iptables. (on deb-based: sudo service docker restart)
但是，如果您只想恢复这些规则而没有重新启动您的服务后，我保存了我的信息，以便您检查并对其进行调整，然后使用 sudo iptables-restore加载。/iptables-docker-ports.backup
however, if you just want to restore those rules without restarting your service, i saved mine so you can inspect, and adjust it to work for you, then load using sudo iptables-restore ./iptables-docker-ports.backup
编辑并将其保存到。/iptables-docker-ports.backup
