# 本章小结

本章介绍了 Docker 镜像的获取、列出、删除以及构建方式。

| 操作      | 命令                                       |
| ------- | ---------------------------------------- |
| 拉取镜像    | `docker pull 镜像名:标签`                     |
| 拉取所有标签  | `docker pull -a 镜像名`                     |
| 指定平台    | `docker pull --platform linux/amd64 镜像名` |
| 用摘要拉取   | `docker pull 镜像名@sha256:...`             |
| 列出所有镜像  | `docker images`                          |
| 按仓库名过滤  | `docker images nginx`                    |
| 列出虚悬镜像  | `docker images -f dangling=true`         |
| 只输出 ID  | `docker images -q`                       |
| 显示摘要    | `docker images --digests`                |
| 自定义格式   | `docker images --format "..."`           |
| 查看空间占用  | `docker system df`                       |
| 删除指定镜像  | `docker rmi 镜像名:标签`                      |
| 强制删除    | `docker rmi -f 镜像名`                      |
| 删除虚悬镜像  | `docker image prune`                     |
| 删除未使用镜像 | `docker image prune -a`                  |
| 批量删除    | `docker rmi $(docker images -q -f ...)`  |

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://yeasy.gitbook.io/docker_practice/di-yi-bu-fen-ru-men-pian/04_image/summary.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
