-### Kube RBAC Proxy
-
-A workload will be created to run the image [gcr.io/kubebuilder/kube-rbac-proxy:<tag>][proxy-images] which is
-configured in the `config/default/manager_auth_proxy_patch.yaml` manifest. It is a side-car proxy whose purpose
-is to protect the manager from malicious attacks. You can learn more about its motivations by looking at
-the README of this project [github.com/brancz/kube-rbac-proxy](https://github.com/brancz/kube-rbac-proxy).
-
-Kubebuilder has been building this image with support for multiple architectures by default.( Check it [here][proxy-images] ).
-If you need to address any edge case scenario where you want to produce a project that
-only provides support for a specific architecture platform, you can customize your
-configuration manifests to use the specific architecture types built for this image.
