The Kubernetes Integration Tax: Prometheus, Cilium and Production Reality
The article warns that the hidden "integration tax"—the effort required to wire CNCF projects together—dominates platform teams, consuming about 80% of their time. It highlights real‑world failures such as Prometheus missing ServiceMonitors for Cilium, duplicate kubelet metrics, and cert‑manager ACME challenges broken by ingress redirects. To tame the chaos, the author advocates a two‑repo GitOps model that centralizes Helm charts, pre‑wired ServiceMonitors, and embedded Cilium NetworkPolicies, while per‑customer repos hold only variable values. This pattern enables single‑click updates, reproducible disaster recovery, and consistent security posture across multi‑cloud clusters.
GPU Autoscaling on Kubernetes with KEDA: Building an External Scaler
KEDA’s default autoscaling ignores GPU metrics, leading to wasted accelerator capacity and higher energy use. To fix this, a custom DaemonSet called keda‑gpu‑scaler reads NVIDIA NVML data on each node and exposes utilization, memory, temperature and power metrics via KEDA’s...
How Jaeger Is Evolving to Trace AI Agents with OpenTelemetry
Jaeger is releasing version 2, rebuilding its core on the OpenTelemetry Collector to ingest traces, metrics, and logs via OTLP. The update adds three open standards—Model Context Protocol, Agent Client Protocol, and Agent‑User Interaction Protocol—to let engineers and AI agents collaborate...
Why Kubernetes Policy Enforcement Happens Too Late—And What to Do About It
Kubernetes policy enforcement often happens too late, after code is merged, leading to costly remediation. While CI/CD scans and admission controllers catch violations, developers lose context, creating feedback loops. Introducing review‑time enforcement—inline policy checks within pull requests—delivers faster, shared feedback...
Introducing Prempti: Policy and Visibility for AI Coding Agents
The Falco team launched Prempti, an experimental, user‑space service that adds policy‑driven visibility and enforcement to AI coding agents such as Claude Code. By intercepting each tool‑call—file reads, writes, shell commands—Prempti forwards the event to Falco’s rule engine, which can...
What Kubectl Debug Doesn’t Tell You: The Silent Evidence Gap
Kubernetes’ API design for ephemeral containers deliberately omits a persistent termination record, so a kubectl debug session’s exit code, duration, and target container disappear once the pod is updated. The `EphemeralContainerStatus` lacks a `lastState` field, unlike regular containers, causing vital...
When AI Agents Become Contributors: How KubeStellar Reached 81% PR Acceptance
In late 2023 the author built the KubeStellar Console, a multi‑cluster Kubernetes dashboard, using two AI coding agents alongside Go, React, and Helm. Initial weeks saw rapid code generation, but unchecked agent actions broke builds and caused cascading failures, prompting...
Building a Cloud Native Platform From the Ground up with Kairos, K0rdent, and Bindy
RBC Capital Markets built a cloud‑native platform that unifies node, cluster, and DNS lifecycle management using Kairos, k0rdent, and bindy. Immutable Kairos images eliminate node drift, while k0rdent (leveraging CAPI and k0s) declaratively provisions and upgrades 50+ clusters across hybrid...
A Decade of Governance: Cloud Custodian at 10 and Its Role in the Agentic AI Era
Cloud Custodian, an open‑source, stateless policy engine, celebrates its 10‑year anniversary as a CNCF incubating project. The tool now serves as a foundational cost‑optimization and security layer for the emerging agentic AI era, where autonomous agents provision GPU fleets, model‑serving...
How to Get Engineering Time Back From Kubernetes Upgrades
Kubernetes upgrades consume disproportionate engineering effort, especially for mid‑size EKS deployments where a single minor version bump across three regions can require four to six weeks of senior time. Industry reports show teams lose roughly 34 workdays per year to...
Benchmarking AI Agent Retrieval Strategies on Kubernetes Bug Fixes
The author benchmarked three Claude Opus‑based AI coding agents—RAG‑only, Hybrid (RAG + local), and Local‑only—against real Kubernetes pull‑request bugs. Each agent received only the issue description and a five‑minute window to produce a patch, with performance measured by speed, token usage, and...
Microcks Becomes a CNCF Incubating Project
The CNCF Technical Oversight Committee voted to promote Microcks to an incubating project. Microcks is an open‑source, cloud‑native platform that turns API contracts—including OpenAPI, AsyncAPI, gRPC, GraphQL, and SOAP—into live mock servers and contract‑testing suites. Since joining the CNCF sandbox...
The Tools Are Ready. So Why Are Most Cloud Native Teams Still Running Three Observability Stacks?
A February 2026 survey of 407 cloud‑native practitioners shows that 46.7% of organizations still run two to three observability tools, while only 7.4% have achieved a single unified stack. Teams cite dashboard and alert configuration (54%) as the biggest setup...
AI Sandboxing Is Having Its Kubernetes Moment
Anthropic unveiled its Mythos model, which independently discovered and exploited zero‑day vulnerabilities in major operating systems and browsers, including a 27‑year‑old kernel bug. The demonstration highlights the danger of running thousands of workloads on a shared Linux kernel in Kubernetes,...
Kubernetes for Platform Teams: Leveraging K0s and K0rdent
The blog demonstrates how combining the lightweight k0s distribution, the multi‑cluster orchestrator k0rdent, and Hosted Control Planes (HCP) on OpenStack creates a scalable, cost‑efficient Kubernetes platform. By centralizing the API server, etcd and controllers in a single management cluster, only...
