Sorry, it works. It took time for us to sort our the internal problem.
BTW, what would you say to making each robot as a single-node cluster (as opposed to worker node) and build a multi-cluster system for multi-robots?
Some cloud-side guy is telling me that Kubernetes is designed to orchestrate containers not nodes, which means that ‘nodeSelector’ is simply a guideline to K8s, not a rule that K8s should follow. In that case, it’s not guaranteed to run the talker at a specific node as we wanted to.
