我试图更改IP docker0的地址172.17.0.1到192.168.149.5，即ens33的IP地址。我搜索了很多参考网站，但没有成功。如何在CentOS 7上设置docker0的IP地址？

I tried to change IP address of docker0 172.17.0.1 to 192.168.149.5, the IP address of ens33. I searched many ref site, but I can't make it. How can I set the ip address of docker0 on CentOS 7?

推荐答案

首先，docker配置文件的位置取决于docker版。如果您使用了一些较新的泊坞窗，则其配置将位于/etc/docker/daemon.json中。
将以下代码放入配置文件中，然后重新启动docker daemon，将更新docker bridge的IP。

First, the position of docker configuration file depends on the docker version. If some newer docker you used, its configuration will be in /etc/docker/daemon.json. Put the following code into the configuration file and restart the docker daemon, the IP of docker bridge will be updated.

{
  "bip": "192.168.1.1/24"
}
