🚨 Action Required: Ensure that you no longer use gcr.io/kubebuilder/kube-rbac-proxy images

[camilamacedo86]

⚠️ The image gcr.io/kubebuilder/kube-rbac-proxy is deprecated and will become unavailable.
You must move as soon as possible, sometime from early 2025, the GCR will go away.

Unfortunately, we're unable to provide any guarantees regarding timelines or potential extensions at this time. Images provided under GRC will be unavailable from March 18, 2025, as per announcement. However, gcr.io/kubebuilder/may be unavailable before this date due to efforts to deprecate infrastructure.

• If your project uses gcr.io/kubebuilder/kube-rbac-proxy, it will be affected.
  Your project may fail to work if the image cannot be pulled. You must take action as soon as possible.

• However, if your project is no longer using this image, no action is required, and you can close this issue.

Using the image gcr.io/kubebuilder/kube-rbac-proxy?

kube-rbac-proxy was historically used to protect the metrics endpoint. However, its usage has been discontinued in Kubebuilder. The default scaffold now leverages the WithAuthenticationAndAuthorization feature provided by Controller-Runtime.

This feature provides integrated support for securing metrics endpoints by embedding authentication (authn) and authorization (authz) mechanisms directly into the controller manager's metrics server, replacing the need for (https://github.com/brancz/kube-rbac-proxy) to secure metrics endpoints.

What To Do?

You must replace the deprecated image gcr.io/kubebuilder/kube-rbac-proxy with an alternative approach. For example:

• Update your project to use WithAuthenticationAndAuthorization:

  You can fully upgrade your project to use the latest scaffolds provided by the tool or manually make the necessary changes. Refer to the FAQ and Discussion for detailed instructions on how to manually update your project and test the changes.

• Alternatively, replace the image with another trusted source at your own risk, as its usage has been discontinued in Kubebuilder.
