容器指定：docker 创建容器时指定容器ip的实现示例

docker network ls

docker network create --driver bridge --subnet=172.18.12.0/16 --gateway=172.18.1.1 mynet

docker network inspect mynet

docker run -e TZ="Asia/Shanghai" --privileged -itd -h hadoop01.com --name hadoop01 --network=mynet --ip 172.18.12.1 centos /usr/sbin/init

docker exec -it hadoop01 /bin/bash

yum install -y net-tools

yum install -y openssh-server
yum install -y openssh-clients
systemctl start sshd.service

useradd brock
passwd brock

docker run -e TZ="Asia/Shanghai" -p 6001:22 --privileged -itd -h hadoop01.com --name hadoop01 --network=mynet --ip 172.18.12.1 centos /usr/sbin/init

route -p add 172.18.12.0 MASK 255.255.255.0 10.0.75.2
