Some applications will use as much resources as possible, like Elasticsearch.
If you are running Docker for development and it uses up all your resources because of such application, you can configure the Docker backend to limit the amount of resources it can use.
If your Docker desktop is using WSL2 as backend, create a .wslconfig file in your user home folder in Windows with the following content
[wsl2]
memory=6GB
processors=4
Then, restart the WSL backend in Powershell
Restart-Service LxssManager
This will also restart Docker Desktop.
This will limit the resources Docker will use to only 6GB RAM and 4 core processors, leaving resources for your other applications and development tools.
