 We are extending Kubernetes by creating an [operator](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/). This involves creating a custom [controller](https://kubernetes.io/docs/concepts/architecture/controller/) and a couple of [Custom Resources](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/). We are using the open source tool [kubebuilder](https://github.com/kubernetes-sigs/kubebuilder) to scaffold our operator files.

 ## Logging
 
-Thundernetes does not attempt to solve game server logging. There are various solutions on Kubernetes on this problem e.g. having a sidecar that will grab all stdout/stderr output and forward it to a logging aggregator.

 ## E2E testing
 
 We are using [kind](https://kind.sigs.k8s.io/) and Kubernetes [client-go](https://github.com/kubernetes/client-go) for end-to-end testing scenarios. Kind dynamically setups a Kubernetes cluster in which we dynamically create and allocate game servers and test various scenarios.
