KEP 6030: Dynamic Resize of Memory-Backed Volumes [alpha]

[natasha41575]

New KEP for Dynamic Resize of Memory-Backed Volumes (alpha targeting 1.37)

Issue link: #6030

This KEP proposes extending the In-Place Pod Vertical Scaling infrastructure to support dynamic resizing of memory-backed emptyDir volumes without pod disruption.

A working proof-of-concept implementation based on the proposed design can be found at kubernetes/kubernetes#138301. The goal of the PoC is to demonstrate the simplicity and feasibility.

Antigravity was used to help with research and writing. However:

• I thoroughly reviewed / fact-checked all claims made by AI to the best of my ability, including running manual tests, combing through the codebase, cross-checking documentation, and prototyping code changes to ensure technical feasibility.
• All design ideas came from humans.
