1. 安装docker
请参考 Linux系统在线安装docker任意版本完整教程
2. dockers启动一个容器查看容器ip
docker run -d --name nginx -p 80:80 nginx #启动一个容器
docker ps -a #查看容器正常运行
docker inspect --format '{{ .NetworkSettings.IPAddress }}' nginx ##查看nginx容器ip
[root@ecs-214609 ~]# docker inspect --format '{{ .NetworkSettings.IPAddress }}' nginx
172.17.0.2
[root@ecs-214609 ~]#
3. 修改docker网卡的IP
修改Docker宿主机的Docker网络
可以在Docker主机上修改/etc/docker/daemon.json文件,添加如下内容
[root@ecs-214609 docker]# cat /etc/docker/daemon.json
{"registry-mirrors" : ["https://mj9kvemk.mirror.aliyuncs.com"],"bip": "192.168.1.5/24","exec-opts":["native.cgroupdriver=systemd"]
}
[root@ecs-214609 docker]# systemctl restart docker
############### "bip": "192.168.1.5/24", 是新添加的
这会将Docker容器分配IP的子网修改为192.168.1.0/24,并且默认网关设置为192.168.1.1。
重启Docker后生效,此后创建的容器会在此子网分配IP
4.验证修改后的结果
[root@ecs-214609 docker]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host valid_lft forever preferred_lft forever

[root@ecs-214609 docker]#
#############看到docker0的IP变化了
docker restart nginx #重启nginx容器
docker ps -a #查看状态
docker inspect --format '{{ .NetworkSettings.IPAddress }}' nginx #查看容器ip
[root@ecs-214609 docker]# docker inspect --format '{{ .NetworkSettings.IPAddress }}' nginx #看到容器IP变化了
192.168.10.1
[root@ecs-214609 docker]#
到这里就成功了！
