我已经搜索了我的问题的答案，但在文档或社区中找不到任何东西。我试图理解为什么当我通过ID删除Docker映像时，会删除多个项目。所有删除行中的哈希值指的是什么?

您应该尝试使用"rmi"而不是"rm">
docker image rm命令"删除一个或多个容器"不是容器映像。检查容器及其ID "docker ps -a"命令
但是，docker rmi命令表示rm = remove i = image。用于移除docker镜像。记住容器是从映像创建的。"docker镜像"或"docker镜像";显示图像、存储库、TAG和图像ID。docker rmi <删除图像。注意，即使可以使用"docker>
