You can adjust the memory size for Docker by following these steps:

Stop Docker service: To stop the Docker service, you can use the command sudo systemctl stop docker.
Modify the Docker configuration file by locating the file, which is typically found in /etc/docker/daemon.json or /etc/default/docker, varying depending on the system and Docker version. Add the following content to the configuration file:

{
  "memory": "2g"
}

The memory size configured here is 2GB, and can be adjusted to another value as needed.

Save the changes and restart the Docker service: After saving the modifications, restart the Docker service by using the command sudo systemctl start docker.
Check if the memory settings are taking effect by using the docker info command to see if the Memory field displays the configured memory size.

By following the steps above, you can successfully configure the memory size for Docker.
