Ubuntu22下docker端口映射失效

端口未被占用, 防火墙未开的情况下, 在docker配置文件加上以下配置生效

vim /etc/docker/daemon.json

{
    "iptables": false,
    "ip-forward": true,
    "registry-mirrors": ["https://qhy6z317.mirror.aliyuncs.com"]
}

或者
cat <<EOF>> /etc/docker/daemon.json
{
    "iptables": false,
    "ip-forward": true,
    "registry-mirrors": ["https://qhy6z317.mirror.aliyuncs.com"]
}
EOF

然后重启docker
systemctl restart docker
