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?


当前回答

更简单的解决方案是在/etc/default/docker文件中添加以下条目

出口http_proxy = " http://HOST "

并重新启动docker服务

服务docker重启

其他回答

另一种情况:如果您的docker网络适配器是禁用的,它将失败与此错误。适配器被命名为“vEthernet (DockerNAT)”或类似的名称。显然,这个适配器以某种方式参与了正常的docker pull行为。让它回来解决问题。

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$

我今天在使用1.10.1时遇到了这个问题,现有的解决方案都不起作用。我试着重新启动,升级,重新生成证书…

我注意到我在机器上创建了很多网络。去除后用:

docker network ls | grep bridge | awk '{print $1}' | xargs -n1 docker network rm

DNS又开始工作了。

注意:您可以忽略有关预定义网络的错误

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

如果你在代理之后,它是不够的,设置HTTP_PROXY和HTTPS_PROXY env。您应该在创建机器时设置它。

参数为——engine-env:

docker-machine create -d "virtualbox" --engine-env HTTP_PROXY=http://<PROXY>:<PORT> --engine-env HTTPS_PROXY=<PROXY>:<PORT> dev
