Docker运行镜像报错处理
运行镜像报错：
[root@centos7-docker ~]# docker run -d -p 9000:9000 --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data --name prtainer-libai portainer/portainer

docker: Error response from daemon: driver failed programming external connectivity on endpoint prtainer-libai (e43b0302d56b51c568f70f833b44e1b61e1a074fcaea60f2ffcc8e0ca5465d55): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 9000 -j DNAT --to-destination 172.17.0.2:9000 ! -i docker0: iptables: No chain/target/match by that name.
(exit status 1)).
1、停止docker服务
输入如下命令停止docker服务
systemctl stop docker
service docker stop
2、保存 iptables
输入如下命令：
iptables-save > /etc/sysconfig/iptables
保存之后的文件内容：

3、启动docker服务
保存了iptables后,可以重新启动docker了。输入如下命令：
systemctl start docker 或者service docker start
4、将docker设置为开机启动
设置过这个就不需要再设置了
systemctl enable docker
5、启动容器
最后启动容器，发现不再报错了。
docker start 容器id/名字
