Do I need SingleStore Tools with the Kubernetes operator?
For most traditional SingleStore DB setups, Toolbox (or Tools) is used to manage, monitor, and interact with your cluster.
However, for a SingleStore Kubernetes cluster, the SingleStore Operator performs most of these functions and Toolbox should not be used. The SingleStore Operator configures memory settings and assures each memsql node has its dedicated resources. The SingleStore Operator must be aware of any changes made to the cluster, therefore, Toolbox will not be developed to manage a SingleStore Kubernetes cluster.
For scaling, making changes to a cluster, or making changes to a cluster's engine variables (for the most part) you should update the associated Kubernetes manifests and apply those changes against the cluster.
Their primary usage for Tools with a SingleStore Operator Kubernetes cluster is for Collecting a Kubernetes (SingleStore Operator) Cluster Report. Besides this function, the SingleStore Operator manages everything else on a Kubernetes cluster.
