Install docker 1.3.0 on CentOS

install_docker.sh

#!/bin/bash

if ! which wget > /dev/null; then
  yum install -y wget
fi

export DOCKER_VERSION=1.3.0

pushd /tmp
  if [ ! -f /usr/bin/docker ]; then
    # First we install the docker-io package to have us setup all the nasty things
    wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
    rpm -ivh epel-release-6-8.noarch.rpm
    yum --enablerepo epel-testing install -y docker-io

    # Then we override with recent binaries and files
    wget https://get.docker.com/builds/Linux/x86_64/docker-$DOCKER_VERSION.tgz
    tar xzf docker-1.3.0.tgz
    sudo mv usr/local/bin/docker /usr/bin/

    wget https://github.com/docker/docker/archive/v$DOCKER_VERSION.tar.gz
    tar xzf v1.3.0.tar.gz
    mv docker-1.3.0/contrib/init/sysvinit-redhat/docker /etc/init.d/
    mv docker-1.3.0/contrib/init/sysvinit-redhat/docker.sysconfig /etc/sysconfig/docker
    chkconfig docker on
    nohup service docker restart
  fi
popd

Just a note that this would not work for CentOS 7 due to the switch to systemd

Right, this one is for CentOS 6.5
