一、创建桥接内网
docker network create net-db --subnet=172.16.0.0/24
docker network ls二、创建容器
docker run \
--name centos1 \
--network net-db \
--network-alias centos1 \
--ip=172.16.0.2 \
--privileged=true \
-dit \
-m 2G \
-w ~/ \
-v /root/docker/centos1:/root \
-p 30022:22 \
-p 30080:80 \
registry.cn-shanghai.aliyuncs.com/exposure/centos:7.8.2003_v1 \
/usr/sbin/init三、检查&进入容器
docker logs centos1
docker exec -it centos1 bash
