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 1.30 introduces the recursiveReadOnly mount option, turning previously imperfect read‑only volume mounts into fully recursive read‑only mounts, while explaining compatibility requirements, required component versions, and usage examples with YAML manifests.
This article recounts a two‑year journey of moving from Ansible‑based EC2 deployments to a Kubernetes‑centric platform, detailing motivations, migration strategies, operational challenges, tooling choices, cost considerations, and practical lessons for teams contemplating a similar cloud‑native transformation.
Celebrating ten years since its first GitHub commit, this article chronicles Kubernetes’s origins, key milestones, community growth, recent technical shifts such as the removal of in‑tree cloud providers, and future directions driven by AI workloads and evolving ecosystem initiatives.
With Kubernetes clusters expanding across multiple environments, choosing the right cross‑cluster networking method is crucial; this article compares six approaches—underlay networks, overlay CNI meshes, Submariner, Skupper, KubeSlice, and others—detailing their core principles, advantages, and limitations to help you select the best fit.
CNCF has added a Cloud Native Artificial Intelligence (CNAI) category to its landscape, highlighting the deep integration of AI and cloud‑native technologies and outlining its significance for standards, tooling, and industry collaboration.
This article provides a comprehensive guide to Kubernetes Service networking, covering container network models, intra‑ and inter‑node pod communication, Service‑Pod relationships, Service types (ClusterIP, NodePort, LoadBalancer, ExternalName), CoreDNS resolution, kube‑proxy operating modes, source IP preservation strategies, and Ingress handling.
This guide compiles a comprehensive set of kubectl and Docker command snippets for retrieving logs, sorting pods, managing secrets, cleaning up resources, performing port‑forwarding, patching storage classes, and other routine Kubernetes and container operations, helping administrators streamline cluster maintenance tasks.
This guide walks through deploying a lightweight K3s cluster unified with virtual machines using Kube‑OVN for multi‑tenant VPC isolation, configuring shared internet via VPN, installing cloud‑hypervisor, setting up Multus for multi‑NIC containers, and provisioning a management web‑app with Tomcat and OpenVPN, providing a complete cloud‑native lab environment.
This article explains the challenges of load balancing traffic across multiple Kubernetes clusters, reviews the shortcomings of commercial, public‑cloud, Karmada, and simple DNS approaches, and details how the open‑source k8gb project uses DNS and CoreDNS to provide an automated, cloud‑native GSLB solution with failover and multi‑cloud support.
Kubernetes v1.30, released in 2024, introduces 45 major updates—including GA for pod scheduling readiness, interactive kubectl delete, CEL‑based admission control, container‑based HPA, new service trafficDistribution, indexed job success policies, volume manager reconstruction, hostIPs list, node log query, default node swap, and recursive read‑only mounts—providing a more conservative yet feature‑rich evolution of the platform.
