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：

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
sshd      1275             root    3u     IPv4 ... TCP *:22 (LISTEN)

docker    9629 9698        root    7u     IPv6 ... TCP *:8000 (LISTEN)

解决方法

我遇到了同样的问题：

使用以下命令编辑/etc/modprobe.d/blacklist.conf：

blacklist ipv6

和/ etc / default / grub：

GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 console=ttyS0"

然后update-grub并重启.
