Docker 修改网桥网段

场景：

服务器： centos7

在Docker上部署了 ExceptionLess 自动创建了网桥：excepitonless_default，默认占用了 172.19.0.0 网段

在华为云上的应用访问此服务器时，数据返回不到华为云上了。

由于华为云上的地址也是172.19.0.0网段上的。

所以返回数据时，直接找到docer 上去了。

解决方式：

修改 docer 上的 excepitonless_default 网桥网段，改成 172.30.0.0

操作：

1. 查看所有网桥

docker network ls

Docker 修改网桥网段

2. 查看网桥地址

ifconfig br-65fbae86767e

Docker 修改网桥网段

3. 查看网桥使用的具体信息

docker network inspect 65fbae86767e

内容如下，里面可看到具体的容器ID

[root@mestest ~]# docker network inspect 64c2fc45bd6e
