Docker provides instructions for how to install Docker on CentOS7: [https://docs.docker.com/installation/centos/](https://docs.docker.com/installation/centos/)

Roughly:

```
curl -O -sSL https://get.docker.com/rpm/1.7.0/centos-7/RPMS/x86_64/docker-engine-1.7.0-1.el7.centos.x86_64.rpm
yum localinstall --nogpgcheck docker-engine-1.7.0-1.el6.x86_64.rpm
service docker start

```

Then to test:

```
docker run hello-world

```
