Overview

OS Images

OS images only include the necessary OSs to launch servers, without any application data or environment configurations. After a FlexusL instance is created from an OS image, it runs on an OS without any applications installed. You can install applications based on your service requirements.

For details about how to create a FlexusL instance from an OS image, see Deploying an Nginx Server Using the CentOS Image.

Application Images

An application image contains the underlying OS (Ubuntu 22.04), application software, initialization data, and runtime environment required by the application. You can use application images to quickly deploy applications, eliminating the need for manual uploads and installation.

For details about how to log in to the application dashboard and manage applications, see Application Management (For Application Images Only).

Private Images

Private images are created from servers on cloud platforms or downloaded from third-party platforms. They can be used by FlexusL instances only after being created or imported using Image Management Service (IMS).

You can use a private image to quickly create a FlexusL instance with the same configuration as the image, or use a private image to change the OS.

Shared images

A shared image is a private image shared by others. It is a way of using private images flexibly.
