docker添加网桥并设置ip地址范围

不知道是因为二进制docker 19.03版本安装后不自动创建docker0网桥，还是其他什么原因，docker的网络模式里面的bridge网桥没有。害的我装个容器映射端口一直看不到端口，也不报错，定位半天才发现没有这个bridge网桥。废话不多说。开干！
先看一下当前情况：

由于是生产环境，所以先要把pod给驱逐一下，以免影响业务

首先说下，直接使用docker network create xx的方式是不行的。因为这种方式创建的网桥并没有挂到虚拟机上，所以不工作，可能需要一些其他的额外配置。这里就不去研究了。提一下，免得各位踩坑。
整个过程如下图，清晰可见。为了方便各位看官老爷，我把命令也复制出来。

[root@dashuaibi-server-103 jpserver]# ip a|grep docker0
[root@dashuaibi-server-103 jpserver]# brctl -h

	addif     	 	add interface to bridge
	delif     	 	delete interface from bridge
	hairpin   	  {on|off}	turn hairpin on/off
	setageing 	 		set ageing time
	setbridgeprio	 		set bridge priority
	setfd     	 		set bridge forward delay
	sethello  	 		set hello time
	setmaxage 	 		set max message age
	setpathcost	  	set path cost
	setportprio	  	set port priority
	show      	[  ]		show a list of bridges
	showmacs  			show a list of mac addrs
	showstp   			show bridge stp info
	stp       	 {on|off}	turn stp on/off

重启完了以后，重新跑要映射端口的容器，对比如下。之前没有添加网桥就没有端口，添加完网桥以后。端口正常映射

最后就是去除污点，让该节点重新恢复调度。
kubectl uncordon 10.168.0.103
