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

我的问题是,docker的默认路径。Sock不在docker daemon所在的位置。

我的默认地址是/home/user/。Docker,但是Docker守护进程在/var/bin中。

我确实设置了env变量来设置正确的地址,这解决了问题

export DOCKER_CONFIG = '/var/bin'

https://docs.docker.com/engine/reference/commandline/cli/

我在ubuntu上安装了docker desktop,所以这可能是问题所在,或者为什么我的DOCKER_CONFIG设置不正确。

其他回答

检查你是否正在使用Docker Machine:)

运行docker-machine env default就可以了。

因为根据文档:

Docker Machine is a tool that lets you install Docker Engine on virtual hosts, and manage the hosts with docker-machine commands. You can use Machine to create Docker hosts on your local Mac or Windows box, on your company network, in your data center, or on cloud providers like AWS or Digital Ocean. Using docker-machine commands, you can start, inspect, stop, and restart a managed host, upgrade the Docker client and daemon, and configure a Docker client to talk to your host. Point the Machine CLI at a running, managed host, and you can run docker commands directly on that host. For example, run docker-machine env default to point to a host called default, follow on-screen instructions to complete env setup, and run docker ps, docker run hello-world, and so forth.

https://docs.docker.com/machine/overview/

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

LINUX

你可以用这个答案https://stackoverflow.com/a/33596140/13997503 即使在使用这个之后,仍然会得到相同的错误。然后你可能已经安装了docker桌面,现在切换到docker引擎

可以使用此命令删除docker桌面服务文件

$ rm -rf ~/.docker

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.

我也有同样的问题。在CentOS 6.5中:

ps aux |grep `cat /var/run/docker.pid`

如果它显示不存在Docker守护进程,那么我输入:

docker -d

然后按Ctrl + D停止Docker。因为我们使用了-d选项,Docker将作为守护进程运行。现在我们可以做:

service docker start

然后我就可以做个分角。这是所有。

注意:如果这些不工作,你可以尝试yum更新,然后再重复这些,因为我yum安装在这些之前。
