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 SIG Network and the security response committee announced the deprecation of Ingress NGINX, outlining its limited maintenance until March 2026, the reasons behind its retirement, and recommended migration paths such as Gateway API or other ingress controllers.
With the rise of the X‑as‑Code paradigm, developers face increasingly complex toolchains and infrastructure; this article explains how platform engineering builds developer portals and capability platforms to deliver efficient, standardized, self‑service cloud‑native development, covering infrastructure evolution, challenges, and open‑source toolsets.
This article explains why Kubernetes namespaces are essential for logical isolation, outlines their core functions such as resource naming separation, RBAC scopes, quota limits and network policies, and provides practical commands, YAML examples, troubleshooting tips, and automation strategies for managing namespaces at scale.
This article dives into advanced Kubernetes troubleshooting techniques, covering persistent volume claim pending errors, event and audit log analysis, dashboard deployment, health probes, temporary containers, and node‑level debugging to help DevOps engineers resolve complex cluster issues efficiently.
This guide walks DevOps engineers through ten essential Kubernetes troubleshooting techniques—covering CrashLoopBackOff, ImagePullBackOff, NotReady nodes, Pending pods, and OOMKilled errors—with step‑by‑step commands, log analysis, and resource management strategies to quickly diagnose and resolve common cluster issues.
Gateway API replaces the traditional Ingress API with a more powerful, standardized, role‑oriented model that supports advanced L4/L7 routing, multi‑protocol traffic, and seamless service‑mesh integration, addressing Ingress’s limitations in scalability, portability, and complex configuration for both platform and application teams.
Kubernetes 1.34, released on August 27 2025, brings mature security defaults, cost‑saving features, and operational improvements such as ServiceAccount token image pulls, KYAML output, per‑deployment HPA tolerance, admission policy mutation, and dynamic resource allocation, all of which are crucial for DevOps teams to test before production rollout.
Kubernetes 1.34 will debut KYAML, a strict YAML subset that adds JSON‑style rules to reduce indentation errors and quoting ambiguities, aiming to make configuration files more reliable while preserving comments and flexibility for cloud‑native workloads.
An analysis of recent Kubernetes cost benchmarks reveals chronic over‑provisioning, with up to 40% idle CPU and 57% idle memory, and offers six community‑validated, actionable automation techniques—including flexible instance selection, arm migration, custom autoscaling, bin‑packing, VPA, and safe Spot usage—to dramatically reduce cloud spend.
This article explains how Kubernetes' reconciliation loop, originally designed for stateless resources, can be extended to manage stateful workloads like PostgreSQL databases using Operators such as CloudNativePG and Atlas, providing a declarative, GitOps‑friendly workflow for provisioning, upgrading, and schema migration.
