Docker Compose to CoreOS

Question

I'm currently learning Docker, and have made a nice and simple Docker Compose setup. 3 containers, all with their own Dockerfile setup. How could I go about converting this to work on CoreOS so I can setup up a cluster later on?

web:
  build: ./app
  ports:
    - "3030:3000"
  links:
    - "redis"

newrelic:
  build: ./newrelic
  links:
    - "redis"

redis:
  build: ./redis
  ports:
    - "6379:6379"
  volumes:
    - /data/redis:/data

taken from https://docs.docker.com/compose/install/

the only thing is that /usr is read only, but /opt/bin is writable and in the path, so:

sd-xx~ # mkdir /opt/
sd-xx~ # mkdir /opt/bin
sd-xx~ # curl -L https://github.com/docker/compose/releases/download/1.3.3/docker-compose-`uname -s`-`uname -m` > /opt/bin/docker-compose

sd-xx~ # chmod +x /opt/bin/docker-compose

sd-xx~ # docker-compose
