@SidFaber, I’m not intending to resurrect a dead thread here, but I happened to find your article when doing some research for a project at work, and your writeup helped us weigh the pros and cons of ROS on Kubernetes.
Based on the issues with multicast you discussed, it seems like this probably isn’t the right fit for us now, but then we found this thread about the new FastDDS discovery server. Admittedly I’m pretty out of my depth on the networking stuff here, but it seems like the server is a pretty direct solution to the multicast issues.
Seeing as the thread is more recent than some of your articles, I was wondering if this is something you’d already seen & tested, or if it’s new and possibly helpful for this particular use case?
