### Cluster Creation Tools
-A common example is that not all Kubernetes clusters are created exactly the same way, meaning the configuration to monitor them may be slightly different. For [kubeadm](examples/jsonnet-snippets/kubeadm.jsonnet) and [bootkube](examples/jsonnet-snippets/bootkube.jsonnet) and [kops](examples/jsonnet-snippets/kops.jsonnet) clusters there are mixins available to easily configure these:

### Internal Registry
Some Kubernetes installations source all their images from an internal registry. kube-prometheus supports this use case and helps the user synchronize every image it uses to the internal registry and generate manifests pointing at the internal registry.
