Docker：添加镜像
在容器中添加镜像文件
例如，使用更新官方映像安装httpd，并将其添加为容器的新映像。该容器是在每次执行docker run命令时生成的，因此添加最新执行的容器如下
[root@linuxprobe ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
docker.io/centos latest 0584b3d2cf6d Less than a second ago 196.5 MB
# start a Container and install httpd
[root@linuxprobe ~]# docker run centos /bin/bash -c "yum -y update; yum -y install httpd"
