Struct RegisterCommandController 

pub struct RegisterCommandController { /* private fields */ }

Presentation layer controller for register command workflow

Coordinates user interaction, progress reporting, and input validation before delegating to the application layer RegisterCommandHandler.

Responsibilities

• Validate user input (environment name format, IP address format)
• Show progress updates to the user
• Format success/error messages for display
• Delegate business logic to application layer

Architecture

This controller sits in the presentation layer and handles all user-facing concerns. It delegates actual business logic to the application layer’s RegisterCommandHandler, maintaining clear separation of concerns.

Implementations

impl RegisterCommandController

pub fn new( repository: Arc<dyn EnvironmentRepository + Send + Sync>, clock: Arc<dyn Clock>, user_output: Arc<ReentrantMutex<RefCell<UserOutput>>>, ) -> Self

Create a new register command controller

pub async fn execute( &mut self, environment_name: &str, instance_ip_str: &str, ssh_port: Option<u16>, output_format: OutputFormat, ) -> Result<Environment<Provisioned>, RegisterSubcommandError>

Execute the complete register workflow

Orchestrates all steps of the register command:

1. Validate environment name
2. Parse and validate IP address
3. Create command handler
4. Register the instance
5. Complete with success message

Arguments

• environment_name - The name of the environment to register the instance with
• instance_ip_str - The IP address string of the existing instance
• ssh_port - Optional SSH port (overrides environment config if provided)
• output_format - Output format (text or JSON)

Errors

Returns an error if:

• Environment name is invalid
• IP address format is invalid
• Environment is not found or not in Created state
• SSH connectivity validation fails
