我正在尝试通过docker-compose建立一个docker环境,但是会出错。
$ docker-compose build
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?
If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
Docker守护程序正在运行
$ sudo systemctl status docker

从centos7存储库安装的Docker:
$ docker --version
Docker version 1.13.1, build 4ef4b30/1.13.1
我尝试根据错误消息设置DOCKER_HOST,但问题仍然存在:
$ echo $DOCKER_HOST
127.0.0.1:2375
有什么想法吗?
答案 0 :(得分:0)
由于某种原因,我的系统中没有docker组,我的用户不属于docker组,并且docker socket文件不在docker组下。
以下命令解决了我的问题:
sudo useradd docker
usermod aG docker mansop
sudo chown root:docker /var/run/docker.sock
