Docker for a clean Zcash install

Do you know any Dockerfile (i’m looking for the list of commands) for running a new node from 0?
Also, it is possibile to store the blockchain in the host memory instead the docker filesystem?

This is probably the best one: https://github.com/zcash/zcash/pull/3908/files

There is a Dockerfile and also instructions on how to use.

This uses Docker volumes for the params and data directories. You could use bind mounts and the zcash.conf file in that example is mounted in that fashion but it’s the same for directories too.
