Configuration and Resource Allocation
After installing Docker Desktop, you may want to adjust the allocated system resources:
- Open Docker Desktop settings: Access the settings or preferences of the Docker Desktop application.
- Adjust resources: Go to the "Resources" section and modify the CPU, memory, and disk space allocations as needed.
- Apply and restart: Click "Apply and Restart" to save the changes and restart Docker Desktop.
With Docker Desktop installed, you can now run Docker commands with the CLI to communicate with the Docker daemon.
