Docker: Installation on Centos 6

System Setup

Have the following setup;

• Centos 6.7 (Note; Docker and Centos 6 are not a great fit, recommended Centos 7 for the 3.10 kernel; see http://www.projectatomic.io/blog/2015/07/docker-centos-6-and-you/)
• EPEL installed and configured (rpm -iUvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm)
• System updates applied (yum update -y)
• SELinux disabled
• IPtables disabled (not even sure this is required but is was disabled on the box)

Install Docker

  yum -y install docker-io
  service docker start
  chkconfig docker on

Thats it!
