修改 Docker 配置,开启容器的 IPv6 功能

修改 Docker 配置,开启容器的 IPv6 功能

以下配置会增加一段自定义内网 IPv6 地址，开启容器的 IPv6 功能，以及限制日志文件大小，防止 Docker 日志塞满硬盘 ：

cat > /etc/docker/daemon.json << EOF
{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "20m",
        "max-file": "3"
    },
    "ipv6": true,
    "fixed-cidr-v6": "fd00:dead:beef:c0::/80",
    "experimental":true,
    "ip6tables":true
}
EOF

systemctl restart docker
