结论一：docker隔离性验证：在docker中运行的java为1.8,；主机中安装的java为1.7
[root@b6fb72b3a8bc /]# java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14,mixed mode)
[root@b6fb72b3a8bc /]# exit
exit
[root@localhost ~]#
[root@localhost ~]# java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (rhel-2.4.5.5.el7-x86_64 u51-b31)
OpenJDK 64-Bit Server VM (build 24.51-b03,mixed mode)
[root@localhost ~]#
结论二：docker镜像虚拟占用空间更小:docker中创建一个centos操作系统仅需要占用196.7MB的磁盘空间
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
docker.io/centos latest 8c59c0a396b7 7 days ago 196.7 MB
结论三：cpu消耗率：在主机中运行一个centos后，cpu利用百分比并无

缺点：
1、只支持64位的系统平台
附：docker装配记录
