Centos7.0-安装docker

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
