链接docker-compose到本地的docker守护进程
我将在Ubuntu“服务器”上运行docker-compose。 首先我尝试了默认安装。 $DOCKER_HOST没有被定义。 然后我把它设置为unix:///var/run/docker.sock
我总是有：
$ docker-compose up ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running? If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
docker-compose.yml守护进程已启动，我docker-compose.yml在Mac安装上工作正常。
供参考：

您可能需要为Docker设置其他环境variables。 一个简单的方法就是在运行docker-compose之前运行下面的命令。
eval $(docker-machine env default)
