Installing the AI Plugin for a Lite Server

Description

NodeTaskHub is a plugin that manages elastic nodes efficiently. It sends tasks and enables automated O&M for ModelArts Lite Servers. It supports high-frequency operations such as Ascend software upgrade, real-time detection, and fault diagnosis, reducing manual intervention risks and ensuring stable and efficient AI service processes.

The Lite Server task center provides you with multiple task templates for creating tasks. Task delivery depends on the NodeTaskHub plugin installed on the Lite Server. For some public images of the Lite Server, the NodeTaskHub plugin is preset. You can choose to automatically install the plugin when purchasing the Lite Server. If it is not installed, manually install it by referring to the following content.
