Can't connect to docker from docker-compose

Question

I installed docker-machine 0.1.0 and docker-compose 1.1.0 on Mac OS 10.8.5.
Docker-machine is running normally and able to connect by docker-machine ssh.

Answer 1

Answer from @srfrnk works for me.

In my situation, I had the next docker-compose.yml file:

  nginx:
    build:
      context: ./
      dockerfile: "./docker/nginx.staging/Dockerfile"
    depends_on:
      - scripts
    environment:
      NGINX_SERVER_NAME: "some.host"
      NGINX_STATIC_CONTENT_OPEN_FILE_CACHE: "off"
      NGINX_ERROR_LOG_LEVEL: debug
      NGINX_BACKEND_HOST: scripts
      NGINX_SERVER_ROOT: /var/www/html
    volumes:
      - ./docker-runtime/drupal/files:/var/www/html/sites/default/files:rw
    ports:
      - 80:80

./docker-runtime owner and group - is root when the other files owner - my user. When I tried to build nginx

Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

I added ./docker-runtime to .dockerignore and it is solved my problem.
