How can I allocate more memory to the Windows VM that Docker for Windows is using when I run a Windows container?

The Dockerfile for my image is very simple right now:

FROM openjdk:11.0-windowsservercore-ltsc2016
RUN mkdir artifactory
ADD artifactory-pro-6.3.3 artifactory/
# systeminfo for debugging purposes only
RUN systeminfo
RUN C:\\artifactory\bin\artifactory

The output of the systeminfo call includes the following:

As you can see, the "Virtual Memory: Max Size" and "Total Physical Memory" attributes are set to be only 1023 MB. My docker info includes the following:

I am using the following command to start my container:

docker run -it --name testing -m 8G artifactory-server:latest

Yet only 1G appears to be available. This is problematic, as when I attempt to start Artifactory, the Java Runtime Environment runs out of memory, and the container isn't spun up.

This is my first foray into Docker for Windows, so it's possible I have something misconfigured. Potential solutions that I have run into make references to VirtualBox, which I don't have due to its incompatibility with Hyper-V and running Windows containers.

I don't see the "Advanced" settings that some others seem to see, which makes me question whether I have the correct version of Docker at all. Here is a picture of what I see.

EDIT: Upon research, it appears that the reason I don't see the Shared Drives, Network, and Kubernetes tabs in the Settings menu is due to the fact that they're only available for Linux containers.

Any direction would be greatly appreciated.

Thank you!
