RUN apk add --no-cache py-pip
Pin docker-compose versions to the time of release - Otherwise the docker-compose version is the latest available at time of build, which may not be compatible or expected - The latest `COMPOSE_VERSION` can be taken by setting the argument blank (or leaving it as is in the case of `latest`) - pip requires the `.*` to denote that we want the latest patch level, eg. just putting `docker-compose==1.11` installs `1.11.0` instead of `1.11.2` - The extra `${COMPOSE_VERSION:+==}` is because pip errors out with `docker-compose==` Fixes #4

RUN pip install "docker-compose${COMPOSE_VERSION:+==}${COMPOSE_VERSION}"
