This guide explains why Prometheus is ideal for Kubernetes monitoring, walks through installing Prometheus, configuring targets and alerts, deploying Alertmanager and Grafana via Helm, and demonstrates testing alerts with load generation, providing complete code snippets and visual results.
The US Air Force’s U‑2 reconnaissance aircraft has adopted a Jenkins‑driven CI/CD pipeline orchestrated by Kubernetes, enabling automated builds, repeatable deployments, rapid threat response, enhanced security, and resource savings, with a detailed step‑by‑step case study illustrating code management, pipeline configuration, container deployment, testing, and RBAC controls.
This guide walks you through setting up an automated code deployment workflow using Docker, Kubernetes Deployments, and a CI/CD tool like Jenkins, covering environment preparation, image building, deployment configuration, pipeline scripting, monitoring, and rollback strategies.
This guide explains how to design a Kubernetes‑based architecture for a large‑scale online store, covering component containerization, auto‑scaling mechanisms, high‑availability deployment, continuous delivery, and monitoring integration to handle traffic spikes reliably.
By integrating Kubernetes with DevOps practices, teams can automate deployment pipelines, achieve dynamic resource allocation, centralize monitoring with tools like Prometheus and Grafana, and treat infrastructure as code, resulting in faster, higher-quality software delivery and improved collaboration between development and operations.
This technical guide details a real‑world Kubernetes deployment, covering a 10‑node cluster specification, master‑worker architecture, containerized frontend and backend services, MySQL persistence, load‑balancing, step‑by‑step deployment procedures, and monitoring setup.
This article presents practical Kubernetes best‑practice cases—including horizontal autoscaling, service discovery with load‑balancing, and health‑check probes—to help engineers build more reliable, scalable, and self‑healing container deployments.
This guide explains how to design and deploy a highly available, scalable e‑commerce platform on Kubernetes by containerizing services, planning clusters, configuring replication, load balancing, persistent storage, monitoring, security, CI/CD pipelines, and provides complete YAML examples for frontend, backend, and database components.
This article introduces Kubernetes as an open‑source container orchestration platform, explains its core objects like Pods, Services, ReplicaSets, and Deployments, clarifies its relationship with Docker, and provides a step‑by‑step example covering deployment, exposure, scaling, rolling updates, and rollback using kubectl commands.
This guide introduces the most commonly used Linux command‑line tools, covering basic commands such as pwd, ls, cd, mkdir, rm, cp, mv and advanced utilities like grep, ps, top, tar, wget, curl, ssh, and scp, with examples and usage tips.
