场景:centos7.3.1611上,docker版本Server:
Version: 17.05.0-ce
API version: 1.29 (minimum version 1.12)
连个容器A,B连接在缺省的docker0 bridge网络上,A 通过publish port方式将80映射到主机的8080上。此时从主机外部访问主机host的IP:8080端口是正常(docker自动添加了相关iptable 放行规则),此时从容器B 访问 hostip:8080则提示被拒绝。原因是:
[root@docker1 ~]# iptables -t filter -nL INPUT -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination

iptable filter表中的input链里的最后拒绝rule(此时目的地址是本地ip,match input 链)
