linux程序只监听了ipv6端口,linux – Docker只会将转发的端口绑定到IPv6接口
有没有办法告诉docker只将转发的端口绑定到IPv4接口？
我在Digital Ocean上运行了一台禁用IPv6的机器：
# echo '1' > /proc/sys/net/ipv6/conf/lo/disable_ipv6
# echo '1' > /proc/sys/net/ipv6/conf/lo/disable_ipv6
# echo '1' > /proc/sys/net/ipv6/conf/all/disable_ipv6
# echo '1' > /proc/sys/net/ipv6/conf/default/disable_ipv6
# /etc/init.d/networking restart
ifconfig报告没有启用IPv6的接口：
# ifconfig

当我启动一个新的docker容器并要求它在容器中将8000转发到8000时,它只在IPv6接口上执行.有没有办法让它只绑定到IPv4接口？
# docker run -p 8000:8000 -i -t colinsurprenant/ubuntu-raring-amd64 /bin/bash
# lsof -OnP | grep LISTEN
