Rancher Desktop does not have a UI for increasing disk size. To increase it:
**On macOS or Linux:**
1. Stop Rancher Desktop completely
2. Create or edit the VM configuration file:
- **macOS**: `~/Library/Application Support/rancher-desktop/lima/_config/override.yaml`
- **Linux**: `~/.config/rancher-desktop/lima/_config/override.yaml`
3. Add or modify the disk size setting:
```yaml
disk: 100GB
```
4. Start Rancher Desktop
5. If Rancher Desktop was previously initialized, you may need to perform a factory reset (Preferences → Troubleshooting → Reset Kubernetes) for the disk size change to take effect.
**On Windows (WSL2):**
The disk is managed by WSL2:
1. Stop Rancher Desktop
2. Run: `wsl --shutdown`
3. Follow Microsoft's guide to increase WSL2 disk size: https://learn.microsoft.com/en-us/windows/wsl/disk-space
**Docker Desktop:**
1. Open Docker Desktop
2. Go to Settings → Resources → Disk image size
3. Increase to at least 60 GB (100+ GB recommended for MongoDB development)
4. Click "Apply & Restart"
