我正在运行Ubuntu,并安装了以下docker软件:
$ docker version
Client:
Version: 1.9.1
API version: 1.21
Go version: go1.4.3
Git commit: a34a1d5
Built: Fri Nov 20 17:56:04 UTC 2015
OS/Arch: linux/amd64
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
$ docker-compose -v
docker-compose version 1.7.0, build 0d7bf73
尝试运行docker-compose时,我收到以下错误提示:
$ sudo 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.
我尝试了以下方法:
systemctl unmask docker.service
systemctl unmask docker.socket
systemctl start docker.service
sudo service docker status

Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Sudo?
当我使用sudo运行时,docker似乎正在运行:
$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
$ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
我该如何解决这个问题?
systemctl
或者你正在使用的任何服务管理器吗? - Rickdocker
用户组中,就像我的提到的重复建议那样?您可以通过在 shell 上执行groups
来检查。 - Rick
