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.
During a traffic peak the CPU surged and thread dumps revealed many MySQL Statement Cancellation Timer threads; this article analyzes the root cause in the MySQL driver, Druid pool and MyBatis configuration, and provides concrete steps to eliminate the unwanted timer threads.
This article explains Linux disk I/O performance metrics, benchmark methods, observation tools like iostat, pidstat, and iotop, and walks through a practical case of diagnosing and resolving an I/O spike caused by the jbd2 journaling process.
This tutorial explains digital certificate fundamentals, common formats, the principles of one‑way and two‑way HTTPS authentication, and provides step‑by‑step Kubernetes configurations—including secret creation and Ingress setup—to implement secure TLS communication.
This article explains the different server storage types—including mechanical HDDs, solid‑state SSDs, various interfaces, RAID arrays, and network‑attached storage—while covering their structures, performance characteristics, Linux device handling, and how to choose the right solution based on cost, capacity, speed, and reliability.
This article explains how to use GitLab CI and Kubernetes namespaces to automate building, testing, and deploying containerized services, ensuring environment isolation, resource control, traceability, and low operational overhead without introducing additional platforms.
This article compares traditional independent config centers with Kubernetes as a config center, explains how to simplify environment variable handling, automatically generate Dockerfiles, and manage build and runtime images in Go projects, offering practical tips and code examples for containerized service deployment.
