Is there a Windows Docker containers eqivalent to tmpfs volumes?

Question

On Linux I can mount RAM via tmpfs as a volume into my Linux containers if I need fast file access for temporary data.

Linux example:

docker run -it --rm --tmpfs /ram-disk:size=1G ubuntu

Is there an eqivalent for Windows containers? (Not Linux containers on WSL2!)

My specific use case looks like this: I have a computer with 128 GB RAM and Windows 11, running a GitLab runner that processes pipelines via Docker CI. Only one container with a RAM disk should run at a time, as this largely utilizes the system resources anyway. I would like to show this container 80 GB RAM as a file system, which is empty when the container is started and whose contents are discarded when the container is stopped.

Answer 1

The tmpfs is not available for Windows. You can use volumes or bind mounts, but these require actual disks.
