Container take too much memory

LXD

I only download the docker and Nvidia driver and Nvidia toolkit in one lxd container. But when I try to publish the container to an image. I find that it cost nearly 800GB. I use df -h，it output

Filesystem                Size  Used Avail Use% Mounted on
zfs-pool/containers/desk   28T  765G   27T   3% /

tmpfs                     504G     0  504G   0% /sys/fs/cgroup

I am confused about it. How can I find out what file cost such a big memory?

Seems about right for the NVIDIA stack, it can easily be over 1GB large.

Though if you just freshly installed things, maybe you also have the package files around? If so, try running apt-get clean.

To figure out what’s using the space, you’ll have to run something like du -sch on the various directories.
