Docker example not working on Debian 12 amd64

[durka]

I tried the Docker setup in the README but it isn't working. Is this a duplicate of #36?

Server:

$ docker run --rm -v ~/.ssh/id_rsa_cpu.pub:/key.pub -v ~/.ssh/id_rsa_cpu:/key -v /tmp --name cpud --privileged -itp 17010:17010 ghcr.io/u-root/cpu:main
