The Cloud Native Technology Community, part of the CNBPA Cloud Native Technology Practice Alliance, focuses on evangelizing cutting‑edge cloud‑native technologies and practical implementations. It shares in‑depth content, case studies, and event/meetup information on containers, Kubernetes, DevOps, Service Mesh, and other cloud‑native tech, along with updates from the CNBPA alliance.
Kubernetes v1.33 introduces the KubeletEnsureSecretPulledImages feature gate, which forces credential verification for cached private images, closing a ten‑year‑old security loophole that allowed Pods to reuse unauthorized images across namespaces regardless of imagePullPolicy settings.
This article analyzes typical Kubernetes security pitfalls—from weak authentication and overly permissive network policies to missing real‑time monitoring, exposed services, outdated versions, and default component settings—and provides concrete, layered mitigation steps and tool recommendations.
Kubernetes 1.33 introduces native sidecar support, enhanced namespace isolation, and dedicated GPU/TPU resource allocation, delivering 64 feature upgrades—including stable sidecar containers, dynamic resource APIs, and user‑namespace security—while providing practical adoption guidance for production environments.
This guide explains how to extract and restore a specific Kubernetes resource from an etcd snapshot using a lightweight, step‑by‑step process that avoids full‑cluster recovery, minimizes downtime, and works with tools like etcdctl, auger, and kubectl.
Korifi provides a Cloud Foundry‑style abstraction layer that simplifies Kubernetes application deployment and management, while OpenCost offers comprehensive, multi‑cloud cost visibility and optimization; together they enable developers to deploy apps easily, monitor pod‑level expenses, and make data‑driven resource allocation decisions.
This guide explains how to use the Kubernetes Resource Orchestrator (Kro) to define a reusable Resource Graph Definition for WordPress, install Minikube and Kro, and deploy multiple WordPress instances on a local Kubernetes cluster.
This article explains the challenges of live‑migrating KubeVirt virtual machines, how Kube‑OVN addresses network‑bridge limitations and IP changes, provides the required VM annotation, step‑by‑step migration commands, and details the multi‑stage migration process that keeps network interruption under 0.5 seconds with no TCP break.
The article examines three modern, cloud‑native and open‑source methods for deploying PostgreSQL—using the CloudNativePG operator on Kubernetes, leveraging Korifi’s self‑service platform, and adopting Neon’s compute‑storage separation—highlighting trends toward cloud‑native infrastructure, self‑service, and open‑source SaaS alternatives.
Scaling Kubernetes across dozens or hundreds of clusters requires standardized core services—networking, security, observability, and automation—so organizations should adopt templated configurations, GitOps tools, centralized monitoring, and automated certificate management to reduce complexity, improve security, and lower operational overhead.
The article introduces the Shift‑Down Security model for Kubernetes, explaining how moving security controls into the platform complements Shift‑Left practices, reduces vulnerabilities and configuration errors, and enables collaborative, automated, and adaptive protection across development, operations, and security teams in cloud‑native environments.
