The Civil Infrastructure Platform (CIP)’s Software Update Working Group, has announced the immediate availability of the CIP SWUpdate Lua Round Robin Handler:
https://gitlab.com/cip-project/cip-sw-updates/swupdate-handler-roundrobin
It is meant to augment SWUpdate’s core features ― such as the recent getroot() addition ― in order to provide a generic run-time dynamic target selection handler, chain-calling other SWUpdate handlers for the heavy lifting works. In its simplest form, such can be a round robin target selection in an A/B deployment scenario, i.e., when currently running on system A, flash system B and vice versa. As with SWUpdate, contributions are more than welcome! So, be invited to poke around and take a look at https://www.cip-project.org/about
