This article explains how to design and implement a Kubernetes platform inspection system that combines Bash scripts and Prometheus queries to monitor cluster health, core component status, and node resources, providing actionable alerts and a flexible automation framework.
This article outlines a typical operations incident workflow, identifies four key stages where large language models can assist, discusses implementation challenges, introduces the Ops framework and Copilot design, and shares practical examples and a real‑world case to help engineers adopt AI‑driven fault management.
This article walks through extending a simple Prometheus Exporter into a full-featured API monitoring solution using Gin-Vue-Admin, detailing backend task scheduling, database schema, multi-protocol checks (HTTP, TCP, DNS, ICMP), dynamic cron management, and frontend integration for managing and visualizing health metrics.
This guide walks you through constructing a complete GitOps‑based CI/CD pipeline using GitLab, GitLab Runner on Kubernetes, Maven, SonarQube, Harbor, Argo CD, and Kustomize, covering code commit, build, test, image publishing, automated deployments, and advanced rollout strategies such as blue‑green and canary releases.
Learn step‑by‑step how to install NVIDIA’s GPU‑operator on a Kubernetes cluster, configure GPU nodes, deploy a Blender workload for GPU‑accelerated rendering, monitor GPU metrics, and troubleshoot common issues, enabling seamless GPU scheduling and graphics rendering in cloud‑native environments.
This article walks through deploying the open‑source LLM serving tool Ollama and the Open‑WebUI interface on a Kubernetes cluster using Helm, covering GPU considerations, configuration files, service exposure, and model management with practical code examples.
This article explains why organizations adopt multi‑cluster Kubernetes for high availability, hybrid‑cloud scaling, and fault isolation, outlines the preparatory steps, compares Federation v1 and v2, introduces Karmada as a CNCF project, and shares practical non‑federated deployment, monitoring, traffic management, and migration techniques with code examples.
This article explains how Ceph cache pools work, compares read‑only and write‑back cache types, provides step‑by‑step commands for creating and configuring cache pools, adjusting CRUSH rules to target SSDs, and outlines safe removal procedures for both cache modes.
This guide explains role‑based access control (RBAC), shows how to map users to roles and permissions, and provides a complete Jenkins pipeline example—including role configuration, permission assignment, and validation—for admin, development, and operations teams.
This tutorial walks through using the Ruoyi project to set up a full CI/CD pipeline with Jenkins, custom Docker base images, Kubernetes deployments, and automated notifications, covering environment preparation, pipeline design, Dockerfile creation, Jenkins configuration, GitLab webhooks, and deployment verification across DEV, UAT, and PROD stages.
