Spring Boots Integration test with postgres using Docker

I use CentOS7 on vagrant to prepare docker environment. let’s start with install docker on CentOS

Install Epel Release


$sudo yum -y install epel-release
$sudo yum -y update


Check linux kernel

I use docker 1.12rc which require linux minimum 3.10.

$uname -r
3.10.0-327.22.2.el7.x86_64


Add Docker Repository

$ 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

Install docker


$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
