每次查看VPS的硬盘时，总会发现DOCKER的OVERLAY占用了太多的硬盘空间。

看这个VPS，58G的空间，这个overlay占用了几十G。我们想办法解决一下。
直接清理无效的、没有使用的镜像、日志、卷等
docker system prune -a -f这个要谨慎点用，后面的 -a -f 就是所有、强制的意思。
你看我这个，直接删除了一堆的没使用的镜像、容器和相关资源。
root@xxxx:~# docker system prune -a -f

4.0M node-20240126.log好了，这些日志我留着也不能当饭吃，毕竟我这不是什么生产力项目，果断决定干掉。不过还不能直接删除，得先停止那个容器，或是直接停止docker，我是直接停止docker,然后删除。
再看一下空间状况
