无法连接到主机上映射的Docker容器端口

标签: docker iptables

我在docker-compose文件中定义了docker容器,并开始将docker-compose与映射端口一起使用。

主机具有两个具有不同IP的网络接口。

interface-1 -> connects to the internet

interface-2 -> Connect to the LAN

我能够通过interface-1连接到docker容器,但是当我尝试使用interface-2时,连接失败:

尝试使用curl 10.0.0.4:8222进行连接会触发以下

  

无法连接到10.0.0.4端口8222:网络无法访问

发出netstat -tulpn表示主机正在侦听映射的端口

docker-compose ps显示:
