@liangyuanpeng
Karmada usually keeps Kubernetes dependencies consistent, that's the reason why we use v0.0.0-20230406110748-d93618cff8a2 (which is consistent with Kubernetes v1.28.5). Given the k8s.io/utils/pointer hasn't been deprecated in v1.28.5(deprecated in v1.29), so I think we can postpone this for a while until we bump Kubernetes v1.29. What do you think?

In addition, we are waiting for kubernetes-sigs/custom-metrics-apiserver#167 to bump Kuberentes dependencies v1.29.

[liangyuanpeng]

Thank you for your detailed explanation, it's make sense for me.

[RainbowMango]

Hi @liangyuanpeng We can get back on this now as the Kubernetes dependencies now is v1.29.4.

Bump k8s.io/utils to 20240102154912-e7106e64919e

We don't need to bump the version, right? We can cleanup the usage of deprecated packages though.

[liangyuanpeng]

I will update it ASAP.
