Explore dynamic cluster scaling using discontiguous CIDRs in this conference talk by Rahul Joshi and Sudeep Modi from Google. Learn how to overcome IP address limitations when horizontally scaling Kubernetes clusters by adding nodes and pods. Discover the benefits of making IP addresses a mutable resource that can be added post-cluster creation, enabling cluster growth on demand. Understand how disjointed CIDRs can help fit clusters into fragmented IP spaces, addressing a common challenge for enterprise customers. Gain insights into GKE's solution for customers and the lessons learned during implementation. Consider proposed ideas for natively solving this issue in Kubernetes to enhance cluster scalability and flexibility.
