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?

我今天早上遇到了同样的问题,下面的问题为我解决了:

$ docker-machine restart default      # Restart the environment
$ eval $(docker-machine env default)  # Refresh your environment settings

这似乎是由于Docker虚拟机进入了一个奇怪的状态。这里有一个开放的github问题

为docker服务创建systemd下拉目录:

$ sudo mkdir -p /etc/systemd/system/docker.service.d

创建一个名为/etc/systemd/system/docker.service.d/http-proxy.conf的文件,添加HTTP_PROXY环境变量:

(服务)

Environment="HTTP_PROXY=http://proxy.example.com:80/"

希望能有所帮助

如果您落后于代理,请使用以下命令

sudo mkdir /etc/systemd/system/docker.service.d

sudo cd /etc/systemd/system/docker.service.d

sudo vi http-proxy.conf

(服务) 环境= HTTP_PROXY = http://proxy-server-ip:端口”“NO_PROXY = localhost, 127.0.0.1” Sudo systemctl daemon-reload sudo systemctl show——property=环境docker Sudo systemctl restart docker

如果你能获取最新的ubuntu,试试这个

sudo docker run -it ubuntu bash

无法在本地找到映像ubuntu:latest

它终于为我工作了:)

参考https://docs.docker.com/network/proxy/ 对我来说,没有http://或https://前缀的代理设置是有效的。 例句: 代理:港口

或以/为后缀,以http://或https://为前缀 e。: http://PROXY:PORT/

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$
sudo service docker stop
sudo service docker start

对我有用。

不知何故,sudo服务docker重启没有工作
