===Running a docker container===
Now that we have downloaded the centos6 image it's time to give it a spin. To start the cento6 container we can issue the follwoing command:
docker run -t -i centos:centos6 bash
This will tell docker to run the centos6 container interactiveley from the local centos repo and start bash. After a few seconds you will be presented with the bash prompt inside the centos6 container:
bash-4.1#
and to check if we are really inside the centos6 container we can display the release version:
cat /etc/redhat-release
which will result in:
CentOS release 6.5 (Final)
From here you can use the normal commands like yum etc.
To exit the container you give the normal 'exit' command, which will stop the centos6 container and bring you back to the prompt of your local server.
To run a container in the background, you need to issue to docker run command with the -d flag instead of the -i flag
