如何从任何码头仓库中拉一张图像？ [英] How to pull a single image from any docker repository?

问题描述

码头仓库包含多个图像。可以从Repository中拉出特定的图像。

当我使用：

  docker pull ubuntu 
  

它下拉了大约8-10个不同版本的ubuntu。 / p>

解决方案

如果有一个特定的图片被标记，可以使用--tag =（或-t）你想要的图像这个命令也有一个简写形式，它只使用图像名称和标签之间的一个冒号。

所以如果你想要标记为量子的ubuntu版本，您可以使用：

  docker pull ubuntu：quantal 
  

较长的表单将是：

  docker pull --tag =量子ubuntu 
 docker pull --t quantal ubuntu 
  

这仍然会拖动历史层用于构建最终的图像，但是将比ubuntu的所有图层更小的子集。

[更新以包含本文从下面的简写。谢谢！]

The docker repositories contains multiple images. Is it possible to just pull the specific image from Repository.

When I use:

docker pull  ubuntu

It pulls down around 8-10 different versions of ubuntu.

解决方案

If there's a specific image that's tagged, you could use the --tag= (or -t) operator to pull the specific image you're looking for. There's a shorthand form for the command as well, which uses just a colon between the image name and the tag.

So if you want the version of ubuntu that's tagged as quantal, you could use:

docker pull ubuntu:quantal

The longer forms would be:

docker pull --tag="quantal" ubuntu
docker pull --t quantal ubuntu

This will still pull the historical layers used to build the final image, but will be a smaller subset than all of the layers for ubuntu.

[Updated to include Ben's note on shorthand from below. Thanks!]
