手动删除卷和容器中的文件后，如何强制Docker释放存储空间？ [英] How to Force Docker to release storage space after manual delete of file in volumes and containers?

问题描述

我的存储空间问题很少。我删除了一些大文件，例如日志文件（在找到大文件的unix之后）。

问题是手动删除了某些Docker文件（在/ var / lib /码头工人/ ...）。删除Docker文件后，我可以看到剩余空间没有变化。 Docker不释放空间。

我重新启动服务Docker，然后问题就解决了。

如何强制Docker从（设备映射器，卷，映像等）释放空间？

解决方案

Docker清理工作根本不存在，您基本上可以自己完成。正如此博客文章中指出的，有多种方法可以实现，但是我宁愿使用第三种方法，方脚本，例如： docker-clean 清理docker留下的一些混乱局面。 / p>

I have few issues with storage spaces. I deleted few big files such as log files (after find unix of big files).

The problem is that delete manually some file of Docker (in /var/lib/docker/...). After deletion of Docker files, I can see that the space left does not change. Docker does not release space.

I restart the service Docker and I the problem persit.

How can I force Docker to release space from (devicemapper, volume, images, ...) ?

解决方案

Docker cleanup job is rather non-existing and you are basically in charge of doing it yourself. There are ways of doing that as pointed out in this blog-post, yet I rather use third-party scripts, e.g.: docker-clean to clean up some of the mess docker leaves behind.
