3. Describe information of Pod: `kubectl describe po <pod_name or container_name>`
4. Delete Pod: `kubectl delete po <pod_name or container_name>`
5. Create template for creating Pod `kubectl run <pod_name> --image=<image_name> --dry-run=client -o yaml > <file_name>.yaml` (this command only generated template file because of `--dry-run=client` option)&#x20;

    # For args it is CMD in docker if you add this property,it will override
    # CMD within image
    args: ["10"]
    ports:
    - containerPort: 80
    
```
