VPS 上的磁盘空间不够, 查了一下文件, 发现有很多文件, 特别是 Docker 安装目录当中有些文件非常大. 怎样理解其中的文件呢. Docker 相关的文件是否可以想办法缩小?

Try to clean up the logs in the image where docker is running. Maybe you can clear some space.
Try this: Shellscript to delete orphaned docker volumes https://registry.hub.docker.com/u/martin/docker-cleanup-volumes/
When you execute remove, you do not clear the cache files pulled down by docker pull, the logs generated by the mirror and other files. The more you pull, the larger the files will become until the disk is full.
