When kubernetes starts the openfire cluster, it can only find the primary node, but other nodes can’t. The author can help solve it. The official can issue a k8s document about openfire cluster.
Openfire should run fine on Kubernetes. However, we do not provide specific instructions for that, as we do not have the experience. If someone in the community would be willing to provide a guide, that would be very welcome.
