Question

当我使用命令docker ps -a时，它会列出几个带有存储库<none>的图像。我假设他们与另一张图片有关，因为时间戳相似。我只是想知道他们的目的是什么？

~~构建映像时，docker会创建临时容器，以便从一个步骤移动到另一个步骤。~~ 但是这些“＆lt; none＆gt;”图像是别的东西;它们是在使用与已经拉出的存储库/标记相同的存储库/标记构建映像时创建的。它们被称为悬空/未标记图像。您可以通过以下方式清理它们：

docker rmi $(docker images -f "dangling=true" -q)

Docker镜像 - 显示存储库<无>的多个图像
