“docker pull ubuntu”不行 [英] "docker pull ubuntu " doesn't work

问题描述

我正在尝试跟踪停靠点你好世界的例子当我输入以下命令，我的密码没有任何反应：

I'm trying to follow the docker hello world example but when I enter the following command and my password nothing happens:

$ sudo docker pull ubuntu
[sudo] password for mike:

它几乎保持了这样的年龄。我已经尝试过两个不同的Ubuntu 12.04桌面，它总是一样的。

It literally stays like that for ages. I've tried on two different Ubuntu 12.04 desktops and it's always the same.

更新：实际发生的是一个新窗口被打开是非常小的，当我扩大它的窗口没有内容。如果我关闭窗口，我会收到消息：

UPDATE: What is actually going on is that a new window is opened which is extremely small, when I expand it the window has no content. if I close the window I get the message:

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 32 requests (32 known processed) with 0 events remaining.

更新2 ：原来这不是一个真正的问题，我正在运行的程序其实是不是docker 。 - 在Ubuntu上安装一个警告字， sudo apt-get install docker 安装另一个名为docker的程序，而不是虚拟化工具。

UPDATE 2: Turns out this isn't a real problem, the program I was running was in fact not docker. - A word of warning, sudo apt-get install docker on Ubuntu installs another program called docker, not the virtualization tool.

推荐答案

在 debian 和 ubuntu 包以及可执行文件/命令被称为 docker.io 。

On debian and ubuntu the package as well as the executable/command is called docker.io.

您应该更好地运行

$ sudo docker.io pull ubuntu

Btw .: docker 是（也）KDE3 / GNOME2 docklet应用程序的系统托盘。

Btw.: docker is (also) a "system tray for KDE3/GNOME2 docklet applications".
