查看docker镜像配置

cat /etc/docker/daemon.json

输出结果

修改docker镜像配置支持ipv6备份文件/etc/docker/daemon.json

cp  /etc/docker/daemon.json /etc/docker/daemon.json.bak

修改文件/etc/docker/daemon.json(注意只追加不覆盖)

{ "experimental": true, "ip6tables": true, "ipv6": true, "fixed-cidr-v6": "2001:db8:1::/64"}

重启docker

systemctl restart docker
