Overview

The Attendedsysupgrade Server project, developed during GSoC 2017, simplifies the sysupgrade process for upgrading firmware on devices running OpenWrt or similar distributions. It offers tools that allow a user to reflash the router with a new firmware version, including all packages, without the need for opkg.

Features

API for Custom Firmware Images: This project is based on an API that allows users to request custom firmware images with selected pre-installed packages.
Web Interface (OpenWrt Firmware Selector): Users can access a simple web interface developed in vanilla JavaScript for device search based on model names and to request firmware images via the ASU API.
luci-app-attendedsysupgrade Package: Provides a tool under System > Attended Sysupgrade that allows users to request and flash a new firmware image with the current set of packages.
CLI Tool (owut): With OpenWrt SNAPSHOT-r26792 or newer, the CLI app auc was replaced with owut to offer a comprehensive CLI tool for device upgrades.
Server Functionality: The project includes a server that listens for image requests, automatically generates valid images, and caches them in a Redis database for faster access.

Summary

The Attendedsysupgrade Server project simplifies the firmware upgrade process for OpenWrt devices by providing tools like a web interface, CLI tool, and server functionality. Users can request custom firmware images, flash them with pre-installed packages, and automate the upgrade process using this project. The installation guide using Podman and podman-compose makes it easy to set up the server for production or development environments.
