Docker No space left

failed to register layer: open /root/.yarn/berry/cache/minimist-npm-1.2.8-d7af7b1dce-10c0.zip: no space left on device

I may have messed something with the permissions of the docker user

“no space left” has nothing to do with permissions. It is what it says, you have no space left. If you see you have, it could be that by the time you check the free space, files were already deleted or never even actually stored since there was nt enough space for the whole data.

I try. I’m new, how can I do this?

It is not about Docker anymore. Yoiu need more space on your system. 3.4 GB is really not much. Not just for Docker, for anything. And if you can, use a separate partition for Docker (/var/lib/docker), so when container or images use a lot of space, it will not fill up your root partition and only docker will be affected…How much space you need, it depends on what you do. I personally would not start with less then 20GB, but if you build lareg images or volumes, create an even larger partition. If you have no free space to use for a new partition, you can add a new disk.
