Topology Aware Subsetting

Enhancement Description

• One-line enhancement description (can be used as a release note): Enabling simple per-service topology aware routing configuration.
• Kubernetes Enhancement Proposal: https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/2004-topology-aware-subsetting
• Discussion Link: https://groups.google.com/g/kubernetes-sig-network/c/wXd1D_fKjqU/m/QnStObQRBAAJ
• Primary contact (assignee): @robscott
• Responsible SIGs: sig-network
• Enhancement target (which target equals to which milestone):
  • Alpha release target 1.20
  • Beta release target 1.21
  • Stable release target 1.24

This is an evolution of #536. I think this is different enough that it deserves a new KEP + issue, but I'm open to feedback on that.

Thanks for this, as a reminder by Enhancements Freeze (Oct 6th), in order to be included in the release:

• The KEP must be merged in an implementable state
• The KEP must have test plans
• The KEP must have graduation criteria.

/milestone v1.20

FTR: Double checked the inflight PR and it meets the above criteria (and wow those test plans!!!). It just needs to merge by next week Tuesday October 6th
