尝试修改/etc/sysconfig中的Docker配置文件，Docker或Docker -network:

(…~ v1.17)

码头工人文件:

OPTIONS= -H fd://

或(v1.18):

docker-network文件:

DOCKER_NETWORK_OPTIONS= -H unix:///var/run/docker.sock

尝试将当前用户添加到docker组:

sudo usermod -aG docker $USER

然后注销并重新登录。

以下Docker的DOC站点:以非root用户管理Docker

1)创建Docker组

sudo groupadd docker 

2)使用户属于docker组，以获得docker组的权限。

sudo usermod -aG docker $USER

检查shell是否设置了DOCKER_HOST环境变量。

env | grep DOCKER_HOST

如果它存在，

unset DOCKER_HOST

然后这应该工作:

docker run hello-world

为了解决这个问题，我必须启用docker服务:

sudo systemctl enable /usr/lib/systemd/system/docker.service

I also had the same issue. The problem was in sockets allocated to docker-daemon and docker-client. First, permission was not set for the docker-client on docker.sock You can set it using "sudo usermod -aG docker $USER" Then check your bash file where the docker-client is running, For me it was on 0.0.0.0:2375, while docker-daemon was running on unix socket.(It was set in the configuration file of dockerd). Just comment the bash-line and it'll work fine. But if you want to make it work on TCP port instead of unix socket, change the configuration file of dockerd and set it on 0.0.0.0.2375 and keep the line in bash as it is if present or set it to 0.0.0.0:2375.

你试过关机再开机吗?: -)

我在Mac电脑上升级到Docker 1.10.1后也遇到了同样的问题。 我做了以下事情:

在Docker快速入门终端上

美元的出口 美元的出口

then

Docker-machine kill default

然后重启Docker快速启动终端

这解决了我的问题。
