I’ve created simple script for installing latest Docker Compose on CoreOS: https://gist.github.com/marszall87/ee7c5ea6f6da9f8968dd

#!/bin/bash
mkdir -p /opt/bin
curl -L `curl -s https://api.github.com/repos/docker/compose/releases/latest | jq -r '.assets[].browser_download_url | select(contains("Linux") and contains("x86_64"))'` > /opt/bin/docker-compose
chmod +x /opt/bin/docker-compose

Just run it with sudo

запускать через

/opt/bin/docker-compose up -d
