When I expose the nodes with a load balancer, Datastax is unable to directly connect to the nodes in the way it wants because it tries to use the IPs internal to the Kubernetes network. We’re not starting from zero, as the creators of the five operators are actively participating in the SIG. K8ssandra consists of the aforementioned Cass-operator Kubernetes operator built and open sourced by DataStax, pre-built and pre-configured integrations with both Prometheus and Grafana, and two tools that came to Cassandra as part of the Last Pickle acquisition: Cassandra Reaper, an anti-entropy repair tool, and Cassandra Medusa, a data backup and restore tool.
