No space left on device - Alpine - only 2 container nginx

Hi Docker Team,
Please help, when trying to download an image, Docker issues a message that “No space left on device”.

I only have one nginx image, two containers, and I see that I have space.
I have a virtual machine with 30 GB of disk, and 2 GB of RAM.
Alpine 3.15.4
Docker version 20.10.14

Images of the message, thank you.
