[camilamacedo86]

Description

⚠️ 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.

We sincerely apologize for any inconvenience this may cause.

Hi @camilamacedo86, thanks for notifying. We've already removed dependency on kube-rbac-proxy in #3833 for ASOv2.
Will discuss what do we do with ASO v1 in our weekly meeting.

At this point, ASOv1 is deprecated and usage is pretty low. We should reach out to the customers we know haven't moved yet and make sure they're aware of this so they're not surprised though.

I think most of them are mirroring both the ASOv1 and kube-rbac-proxy images, but I'm not 100% sure about that.

[matthchr]

We've contacted customers still using ASOv1 and notified them they need to move. ASOv2 customers may also be impacted if they're running older versions of ASO, which I haven't explicitly reached out about, but it at least should be easy to fix if anybody gets impacted.

We will leave this issue open until after March 18, 2025.
