我刚刚在他们的网页上安装了Docker-Toolbox

我从Docker快速入门终端开始,如下所示

                        ##         .
                  ## ## ##        ==

bash-3.2$ 

但当我尝试执行docker拉hello-world时,这是我看到的

bash-3.2$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.
bash-3.2$ 

怎么了?

我有同样的问题与boot2docker和修复它重新启动它:

boot2docker restart

其他回答

在Windows 7上,如果你认为你落后于代理

Logon to default machine $ docker-machine ssh default Update profile to update proxy settings docker@default:~$ sudo vi /var/lib/boot2docker/profile Append from the below as appropriate # replace with your office's proxy environment export"HTTP_PROXY=http://PROXY:PORT" export"HTTPS_PROXY=http://PROXY:PORT" # you can add more no_proxy with your environment. export"NO_PROXY=192.168.99.*,*.local,169.254/16,*.example.com,192.168.59.*" Exit docker@default:~$ exit Restart docker machine docker-machine restart default Update environment settings eval $(docker-machine env default)

以上步骤略有调整,但请参见故障排除指南:https://docs.docker.com/toolbox/faqs/troubleshoot/#/update-varlibboot2dockerprofile-on-the-docker-machine

我在VBOX 5.10中使用Docker VM在我的MAC(主机)上运行Docker时遇到了这个问题。这是一个网络问题。简单的解决方法是向VBOX映像添加一个桥接网络。您可以使用虚拟机附带的NAT配置,但需要将ssh端口从50375更改为2375。

我猜您有网络问题。你背后有代理人吗?它是否有可能过滤到docker的连接。IO或阻塞docker用户代理?

我安装了工具箱,运行了你的测试。它工作得很好,在这里:

Hello from Docker.
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

bash-3.2$

在Windows系统上,当我从工作网络转移到家庭网络时,就发生了这种情况。

要解决这个问题,运行:

docker-machine停止 docker-machine开始 docker-env "C:\Program Files\Docker Toolbox\ Docker -machine.exe" env |调用表达式

在Windows 10上。只需右键单击systray docker图标-> Settings…-> Rest ->重启Docker
