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

 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
  保存之前文件内容:

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10001 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10002 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10003 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 10004 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

保存之后的文件内容:

-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
# Completed on Sat Nov 24 13:53:13 2018
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
