I use CentOS7 on vagrant to prepare docker environment. let’s start with install docker on CentOS
$sudo yum -y install epel-release
$sudo yum -y update
I use docker 1.12rc which require linux minimum 3.10.
$uname -r
3.10.0-327.22.2.el7.x86_64

$ sudo tee /etc/yum.repos.d/docker.repo <<-'EOF' [dockerrepo] name=Docker Repository baseurl=https://yum.dockerproject.org/repo/experimental/centos/7/ enabled=1 gpgcheck=1 gpgkey=https://yum.dockerproject.org/gpg EOF |
$sudo yum -y install docker-engine
Some case you will be installed previous version of docker (1.11xx) because you have some dependency package that pre-installed with previous version.
To check and remove that package use following command line.
$sudo yum -y remove $(rpm -qa|grep docker)
$sudo yum -y install docker-engine
