如何查看docker镜像内容 [英] How to see docker image contents

问题描述

我做了一个 docker pull 并且可以列出下载的图像.我想看看这张图片的内容.在网上搜索了但没有直接答案.

I did a docker pull and can list the image that's downloaded. I want to see the contents of this image. Did a search on the net but no straight answer.

推荐答案

您可以使用该图像运行交互式 shell 容器并探索该图像具有的任何内容.

You can just run an interactive shell container using that image and explore whatever content that image has.

例如:

docker run -it image_name sh

或者关注带有 entrypoint

docker run -it --entrypoint sh image_name

或者，如果您想查看映像的构建方式，即其 Dockerfile 中的步骤，您可以:

Or, if you want to see how the image was build, meaning the steps in its Dockerfile, you can:

docker image history --no-trunc image_name > image_history

这些步骤将被记录到 image_history 文件中.

The steps will be logged into the image_history file.
