• --image-id=image_id: Defines the image template to create the instance, ensuring consistency and compliance with specific application requirements.

Example Output:

Instance successfully created with ID: i-abcdef1234567890
Domain: example.com
State: pending

Use Case 3: Gather Information on a Particular Instance

Code:

VBoxManage cloud --provider=provider_name --profile=profile_name instance info --id=unique_id

Motivation for Use: Gathering detailed information on a specific instance helps in understanding the instance’s current status, configuration, and usage. This is essential for performance analysis, troubleshooting, and management reporting.

Explanation:

• --provider=provider_name: Specifies which cloud provider’s API to interact with.
• --profile=profile_name: Designates the user profile for authentication and additional settings.
• instance info: Specifies the action to retrieve information about a particular instance.
• --id=unique_id: Clearly identifies which instance’s data is to be retrieved, ensuring accuracy.

Example Output:

Instance ID: i-unique123
State: running
Memory: 8GB
CPU: 4
IP Address: 192.168.1.10

Use Case 4: Terminate an Instance

Code:

VBoxManage cloud --provider=provider_name --profile=profile_name instance terminate --id=unique_id

Motivation for Use: Terminating instances is key to cost management and resource optimization in cloud environments. It ensures that no unnecessary resources are consuming budget or system capacity.

Explanation:

• --provider=provider_name: Ensures the termination process is executed in the correct cloud environment.
• --profile=profile_name: Uses the specified credentials for securing the process.
• instance terminate: The action within the command aimed at ceasing the operation of a virtual machine.
• --id=unique_id: The specific identifier of the instance to be terminated, preventing accidental or erroneous actions.

Example Output:

Instance with ID i-unique123 has been successfully terminated.

Use Case 5: List Images within a Specific Compartment and State

Code:

VBoxManage cloud --provider=provider_name --profile=profile_name list images --compartment-id=compartment_id --state=available

Motivation for Use: This command is essential for identifying available images that can be used for new instance deployments. Keeping track of images ensures efficient resource management and version control.

Explanation:

• --provider=provider_name: Points to the intended cloud service provider.
• --profile=profile_name: Specifies which user settings to apply.
• list images: The action focusing on retrieving details about images.
• --compartment-id=compartment_id: Filters images by specific projects or groups within the organization.
• --state=available: Limits the results to images ready for deployment.

Example Output:

Image ID: img-12345
Display Name: Ubuntu 20.04 LTS
State: available
Compartment ID: compartment_id

Use Case 6: Create a New Image

Code:

VBoxManage cloud --provider=provider_name --profile=profile_name image create --instance-id=instance_id --display-name=new-image --compartment-id=compartment_id

Motivation for Use: Creating custom images from existing instances is critical for scaling and rapid deployment of standardized environments. This command helps to capture the state of an existing setup for future use.

Explanation:

• --provider=provider_name: Specifies the targeting of the cloud provider.
• --profile=profile_name: Identifies the user profile for operation.
• image create: The command initiates the creation of a new disk image.
• --instance-id=instance_id: Defines the source instance from which to create the image.
• --display-name=new-image: Provides a human-readable name to easily identify the created image.
• --compartment-id=compartment_id: Assigns the image to a specific compartment, aiding organization and management.

Example Output:

Image created successfully with ID: img-67890
Display Name: new-image

Use Case 7: Retrieve Information about a Particular Image

Code:

VBoxManage cloud --provider=provider_name --profile=profile_name image info --id=unique_id
