With the recent v1.35 release of Kubernetes, support for a kubelet configuration drop-in directory is generally available. The newly stable feature simplifies the management of kubelet configuration across large, heterogeneous clusters. With v1.35, the kubelet command line argument --config-dir is production-ready and fully supported, allowing you to specify a directory containing kubelet configuration drop-in files. All files in that directory will be automatically merged with your main kubelet configuration. This allows cluster administrators to maintain a cohesive base configuration for kubelets while enabling targeted customizations for different node groups or use cases, and without complex tooling or manual configuration management. The problem: managing kubelet configuration at scal
Phase 4 / Search Layer
Find transmissions by signal, source, or topic.
Search returns normalized transmission metadata and canonical links only. This keeps the frontend clean while the ingestion system remains separate.
This article is a mirror of an original that was recently published to the official etcd blog. The key takeaway? Always upgrade to etcd v3.5.26 or later before moving to v3.6. This ensures your cluster is automatically repaired, and avoids zombie members. Issue summaryRecently, the etcd community addressed an issue that may appear when users upgrade from v3.5 to v3.6. This bug can cause the cluster to report "zombie members", which are etcd nodes that were removed from the database cluster some time ago, and are re-appearing and joining database consensus. The etcd cluster is then inoperable until these zombie members are removed. In etcd v3.5 and earlier, the v2store was the source of truth for membership data, even though the v3store was also present. As a part of our v2store deprecation
