can't Creating a site in Crafter CMS 3.1.0

Unable to Create site getting error notification

I followed the instructions given here : https://docs.craftercms.org/en/3.1/getting-started/quick-start-guide.html

Steps followed:

I cloned Crafter CMS Docker Compose repo from GitHub and then I started the container from authoring directory using the docker-compose up command And then I tried to Create a site in Crafter Studio but I got error notification which says "Unable to Create site: contact system administrator"

I am using Docker Desktop Community in my windows 10 64 bit

Docker - Version 2.0.0.3 (31259) Crafter CMS - Version 3.1.0 OS - Windows 10 64 bit Browser: Google Chrome

I expected site creation but I got error notification which says "Unable to Create site: contact system administrator"

Error Nofication :

The problem is RAM. You need to give it 8GB+ of RAM to be able to start all the services (including Elasticsearch).
