Add the necessary repo to the instance:

cd /etc/yum.repos.d

sudo vim docker-ce.repo

Add these lines on top

[centos-extras]

name=Centos extras - $basearch

baseurl=http://mirror.centos.org/centos/7/extras/x86_64

enabled=1

gpgcheck=0

sudo yum install -y docker-engine

sudo systemctl start docker

sudo systemctl enable docker

sudo usermod -aG docker $USER

logout and login again 

docker ps -a

Now install Docker Compose.

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

check that was installed with

docker-compose -v

Because you always need it....

sudo yum install -y git
