Exploring industry DevOps practices and technical expertise.
This guide walks you through provisioning a local Kubernetes environment using Terraform and Kind, installing essential tools like kubectl and ArgoCD, and deploying a cloud‑native continuous‑delivery pipeline, providing a repeatable setup for DevOps hands‑on training.
The article outlines essential continuous delivery, architectural, product, lean management, and cultural capabilities—such as version control, automated deployment, trunk‑based development, test automation, value‑stream visibility, lightweight change approval, and supportive leadership—that together drive high‑performance DevOps outcomes.
This tutorial walks through creating a complete GitOps CI/CD pipeline on OpenShift using Tekton for builds and ArgoCD for declarative continuous delivery, covering installation, secret management, pipeline definition, webhook configuration, and verification of automated deployments.
This article introduces KubeLinter, an open‑source tool that scans Kubernetes YAML files and Helm charts for best‑practice compliance, explains why it is useful, shows installation methods, provides usage examples, and details configuration and integration options for secure, production‑ready deployments.
This article explains how to perform data‑driven A/B testing in progressive delivery using Argo Rollouts Experiments on Kubernetes, covering the concepts, required resources, YAML manifests, command‑line steps, and the benefits of combining A/B tests with canary deployments.
This article outlines comprehensive best‑practice guidelines for building Kubernetes applications, covering scalability design, containerization, pod scope, configuration management, health probes, deployments, service discovery, storage, monitoring, security, and CI/CD integration to achieve robust, highly available workloads.
The 2023 CNCF user survey of Argo CD and Argo Rollouts reveals high adoption rates, strong Net Promoter Scores, dominant usage by DevOps and platform engineers, expanding production deployments, and growing ecosystem integrations, highlighting opportunities and challenges for the GitOps and progressive delivery landscape.
This article explains what multi‑architecture Docker images are, why they are useful, and provides step‑by‑step instructions for building them with traditional Docker commands or Docker buildx, integrating the builds into Jenkins and GitHub Actions pipelines, promoting images across environments, scanning for vulnerabilities, and important considerations to keep in mind.
The article explores David Farley's decades‑long experience in software engineering, highlighting his early automation work, contributions to the Agile Manifesto, the principles of Continuous Delivery, critiques of traditional waterfall methods, and practical guidance on Test‑Driven Development and learning‑oriented development to deliver business value.
This article reviews ten popular Kubernetes monitoring tools—including Helios, Prometheus, New Relic, Grafana, DataDog, Sysdig, Zabbix, AppDynamics, Dynatrace, and Sensu—detailing their key features and how they help improve performance, reliability, and observability of containerized applications.
