Installing docker is very simple:
<sxh bash>
yum install docker
</sxh>
<sxh bash>
service docker start
</sxh>
Now start the service and enable from boot:
<sxh bash>
sudo docker run hello-world ; chkconfig docker on
</sxh>
\\
To test if it has been installed properly you can run the following command:
<sxh bash>
sudo docker run hello-world
</sxh>
You are looking for the following line to see if it has been installed correctly:
<sxh bash>
Hello from Docker.
This message shows that your installation appears to be working correctly
</sxh>
