Centralized Firmware Upgrader for OpenWrt

Hi everyone,

the latest OpenWISP 2020-12 release which was just released today includes the first version of the new Firmware Upgrader module, which at the time of writing supports only OpenWRT and provides the following features:

  • Stores information of each upgrade operation which can be seen from the device page
  • Automatic retries for recoverable failures (eg: firmware image upload issues because of intermittent internet connection)
  • Performs a final check to find out if the upgrade completed successfully or not
  • Prevents accidental repeated upgrades
  • Single device upgrade
  • Mass upgrades
  • Possibility to divide firmware images in categories
  • Possibility of writing custom upgraders for other firmware OSes or for custom OpenWRT based firmwares
  • Configurable timeouts
  • Extensible

There's still work to do to improve this module, but at least the first version is now available in the official release and we can start collecting feedback.

I publish it here in the hope that it will be useful to some OpenWRT users.

great work.
i would love to see it upstreamed into Openwrt

quality code... thanks for sharing! ( and all the effort behind the scenes )

Thanks for your support.

What do you mean exactly for being upstreamed?

The agent (openwisp-config) is present in the official packages but needs to be updated.
OpenWISP needs to be installed on at least one server.
