This guide explains how KubeVela, as a declarative application delivery control plane, leverages GitOps with FluxCD to provide end‑to‑end workflows, infrastructure and application deployment, multi‑cloud strategies, and automated CI/CD pipelines for both platform operators and developers.
This guide walks through deploying Loki via Helm, configuring the OpenTelemetry Collector to use a filelog receiver and Loki exporter, and enabling Kubernetes event collection, providing step‑by‑step commands and YAML snippets for a complete logging pipeline in a Kubernetes cluster.
This guide walks through installing OpenTelemetry Collector on a Kubernetes cluster using Helm, configuring DaemonSet and Deployment collectors, integrating Prometheus for metrics, and customizing receivers, processors, and exporters to achieve comprehensive observability of nodes, pods, containers, and cluster resources.
This guide walks through automating frontend development tasks—using Husky for Git hooks, lint‑staged for staged file filtering, commitlint for standardized commit messages, ESLint and @typescript-eslint for code checking, and Prettier for formatting—providing installation commands, configuration snippets, and practical usage tips for React + TypeScript projects.
This guide walks through the two most typical Nginx HTTP‑to‑HTTPS redirection setups—direct client access and proxy‑mediated access—showing why the simple 301 rule works in the first case, why it fails with an upstream proxy, and how to correctly use request headers and Nginx variables to achieve reliable redirects.
Container runtimes are essential for managing containers in Kubernetes, and this article explains their core functions, compares Docker and containerd, details the CRI interface, explores supported backends, and provides practical command references to help you choose the optimal runtime for cloud‑native deployments.
This guide explains how to containerize a React front‑end application using Docker, set up CI/CD pipelines with GitHub Actions, optimize builds with pnpm caching and buildx for multi‑architecture images, inject environment variables, and deploy the resulting container to Kubernetes.
This guide explains how to customize Nightingale monitoring alerts to include the number of pending alerts, the recovery metric value, and a link to view active alerts, using a small Python script, webhook integration, and template modifications, along with necessary database queries and Prometheus API calls.
This guide demonstrates how to collect and store metrics, traces, and alerts in OpenObserve by configuring Prometheus remote_write, integrating OpenTelemetry SDKs and Collector, and setting up alert templates and destinations, complete with Kubernetes deployment examples, dashboard creation, and query techniques.
OpenObserve is a Rust‑based, cloud‑native observability platform that offers log, metric, and trace collection with up to 140‑times lower storage costs than Elasticsearch, supports both single‑node and HA deployments, provides a built‑in UI, and includes detailed installation and query examples for Kubernetes environments.
