What is Docker command does in centos?

Hi All,

What is the use of docker command in centos? And what are docker containers and its functionality,
can any one give an example for docker containers and where do we use them exactly?

from this url i found dockers can be installed on only Centos7 , “http://docs.docker.com/v1.8/installation/centos/

Thanks in advance…

Docker nothing but command line virtulization. Containers are nothing but files (Configured files). These containers are run through dockers. Containers acts like operating system when they are run. You can run any number of Operating systems through dockers. The advantage of docker are there are no limitations for sharing the hardware resources.

We can just link the directories in containers and any operating system can use the same directories.
