Docker无法连接到Docker守护进程

当我把Docker版本更新到0.8.0后，我在输入sudo Docker version时得到了一个错误消息:

Client version: 0.8.0
Go version (client): go1.2
Git commit (client): cc3a8c8
2014/02/19 12:54:16 Can't connect to docker daemon. Is 'docker -d' running on this host?

我按照说明，输入命令sudo docker -d，我得到了这个:

[/var/lib/docker|2462000b] +job initserver()
[/var/lib/docker|2462000b.initserver()] Creating server
open /var/lib/docker/aufs/layers/cf2414da53f9bcfaa48bc3d58360d7f1cfd3784e4fe51fbef95197709dfc285d: no such file or directory[/var/lib/docker|2462000b] -job initserver() = ERR (1)

我怎么解决这个问题?

当前回答

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。

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.

Linux

Linux安装后步骤文档揭示了以下步骤:

创建docker组。 Sudo groupadd docker 将用户添加到docker组。 sudo usermod -aG docker $(whoami) 退出并重新登录以确保docker以正确的权限运行。码头工人开始。 Sudo服务docker启动

Mac OS X

正如Dayel Ostraco所说，有必要添加环境变量:

docker-machine start # Start virtual machine for docker
docker-machine env  # It's helps to get environment variables
eval "$(docker-machine env default)" # Set environment variables

docker-machine start命令输出注释来指导这个过程。

您可以使用该命令

sudo service docker stop && sudo service docker start

sudo service docker restart

简单地重新启动它。

这种情况通常不会发生。但是有一天，消息出现了(如下所示)，一个简单的重启修复了它

unix:///var/run/ Docker .sock无法连接到Docker守护进程。docker守护进程正在运行吗?

执行ps aux | grep docker查看守护进程是否正在运行。如果没有，执行/etc/init.d /码头工人开始
