docker - 将docker-compose链接到本​​地​​docker守护程序

Question

我将在Ubuntu“服务器”上运行docker-compose。
首先，我尝试了默认安装。未定义$DOCKER_HOST。然后我将其设置为unix:///var/run/docker.sock
我一直有:

$ 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守护程序已启动，我的 docker-compose.yml在Mac安装上工作正常。

仅供引用:

您可能需要为Docker设置其他环境变量。一种简单的方法是在运行docker-compose之前运行以下命令。

eval $(docker-machine env default)
