#### docker运行报错docker0: iptables: No chain/target/match by that name. ####

最近在一个新的服务器上装服务，没有安装`iptables` ,后来安装了`iptables` 之后，忽然发现我的`docker` 不能运行了。  
  注意，可能别人的不行，我这个原因是，开始在新服务器上没有安装`iptables` ，先安装的`docker` ,后来才停用默认的`firewall` ,安装了`iptables`,就出现了这样的问题。其他原因，我不知道这方法可行不？先看错误：  
  运行时报出了以下错误：

启动docker服务报错
    Error response from daemon: No such container: yn-userservice-30000
    26126ca87430b74c3987817492cc890e72c36e2fec10d807e362a12f22365160
    /usr/bin/docker-current: Error response from daemon: driver failed programming external

     destination 172.17.0.2:30000 ! -i docker0: iptables: No chain/target/match by that name.

后来在网上找了下，发现解决办法很简单，如下：

###### 1、停止docker服务 ######

输入如下命令停止docker服务

systemctl stop docker  或者service docker stop

停止成功的话，再输入`docker ps` 就会提示出下边的话：

Cannot connect to the Docker daemon. Is the docker daemon running on this host?

###### 2、保存 iptables ######

输入如下命令：

iptables-save >  /etc/sysconfig/iptables

我发现 防火墙的配置文件`/etc/sysconfig/iptables`前后文件如下，当然我是看不懂了，我也就会设置个入站端口

###### 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 容器名字
