最近在使用dokcer过程中出现了很多因网络问题导致的服务异常,比如:reids端口开放在了公网上,白天上班发现程序流程出错,后来查redis的操作日志发现每天晚上有执行flushall命名。还有就是在搭建overlay网络时,开始不太熟悉docker的,就按照网络上的配置0.0.0.0:2360,结果三台服务器在晚上都被用来挖矿。</p><p> 上面出现的当然都是被黑的,还有测试环境搭建了flannel网络时,ping通但是telnet不通的怪异现象。</p><p> 等等,上面所有的问题都与docker iptables、 linux iptables、ufw、firewalld 相关。所以今天就打算来补习下linux防火墙。</p></div><div class="article-info
