Limit WSL2 Memory Usage when using Docker for Windows

You can limit docker-windows memory usage by adjusting some parameters in wsl2 configuration.

First, close any instances of Docker Windows currently running and create a new file named .wslconfig in your user home directory, like C:\Users<username>:

[wsl2]
memory=4GB
processors=5

Save the file, open a Power Shell window with administrator privileges and execute the following command to restart any WSL2 instances and apply the new confiuguration:

Restart-Service LxssManager

After this, just restart Docker-Windows to get an instance of WSL2 with the new configuration applied.

Extremely helpful. I have 12GB of RAM and docker was consuming almost 10GB.

I limited docker to 2GB and it's working better than after.

Thanks a lot.
