Port Management

The AutomateLinux daemon acts as a central registry for application ports, allowing cross-component service discovery.

CLI Usage

Use the high-level d command (which aliases daemon send) to manage ports.

Setting a Port

Registers a port for a specific key (e.g., pt for Public Transportation).

d setPort --key pt --value 3001

Getting a Port

Retrieves the currently registered port for a specific key.

d getPort --key pt

Listing All Ports

Displays a list of all registered applications and their assigned ports.

d listPorts

Deleting a Port

Removes the port mapping for a specific key.

d deletePort --key pt

How it Works

Persistence

The daemon stores these ports in the settings table of its MySQL database. The keys are automatically prefixed with port_ (e.g., port_pt).

Integration

Component logic (like in mainCommand.cpp or InputMapper.cpp) can retrieve these values using the SettingsTable manager:

string port = SettingsTable::getSetting("port_pt");
if (!port.empty()) {
    string url = "http://localhost:" + port;
}

Port Allocation Scheme

• 3000-3499: App prod/dev ports (2 per app, sequential)
• 3500+: Special operational ports (WebSocket servers, bridges, etc.)

Current Port Registry

[!NOTE] Port management is useful for macros that need to launch browsers or proxy services to specific local addresses without hardcoding them in the binary.
