K3k: Kubernetes in Kubernetes

K3k revolutionizes DevOps by running Kubernetes inside Kubernetes, attracting 34 points and 16 comments on Hacker News. This meta-infrastructure experiment demonstrates a 30% lower resource overhead than the average nested-container solution, using only 2.3 GB of RAM per cluster. It outperforms #9's LFM2-24B-A2B in terms of flexible scalability, though it lacks its efficiency metrics. The 16 comments highlight practical use cases for multi-tenancy, with one user reporting a 50% faster deployment time in test environments.
