This guide presents essential cURL commands for service health checks, API testing, file transfer, debugging, Kubernetes interactions, monitoring, load balancing, and webhook triggering, demonstrating how the versatile tool can streamline automation, CI/CD pipelines, and daily DevOps tasks.
This guide explains why traditional monitoring falls short in cloud‑native environments and shows step‑by‑step how to install and configure the Prometheus Operator on Kubernetes using Helm, including custom image settings, storage configuration, and verification of the deployed services.
This article provides a comprehensive overview of Kubernetes architecture, detailing the control plane components, worker node services, and the end‑to‑end workflow that enables automated deployment, scaling, and management of containerised applications in cloud‑native environments.
This step‑by‑step guide walks you through initializing a Kubernetes controller project with kubebuilder, writing the Reconcile logic, debugging and performance monitoring, building and pushing Docker images, and deploying the controller using Helm charts, while also covering metrics collection, RBAC configuration, and best practices for cloud‑native workloads.
This guide walks you through installing the kubectl cert-manager plugin via krew or offline, checking certificate renewal status, manually renewing certificates, and understanding key timestamps, all to streamline Kubernetes certificate management and boost operational efficiency.
This guide explains how to monitor Longhorn storage in Kubernetes by collecting metrics with Prometheus, configuring scraping, verifying data collection, and visualizing everything in Grafana, enabling proactive performance tuning and reliable operations.
This guide walks you through preparing three AlmaLinux servers, disabling firewalls and SELinux, installing Containerd as the CRI, adding Kubernetes repositories, installing kubeadm, kubelet and kubectl, configuring the runtime, and verifying each component so you can confidently bootstrap a production‑ready Kubernetes cluster.
This guide walks you through securing the Longhorn UI in a Kubernetes environment by configuring basic authentication and enabling HTTPS via Ingress and cert‑manager, including prerequisite setup, secret creation, Helm upgrades, and verification steps to ensure production‑grade protection.
The article explains how automating thread dump creation and download in Kubernetes using tools like Fabric8, Prometheus, and CI/CD pipelines dramatically improves fault‑diagnosis speed, data centralization, real‑time capture, and integration with testing frameworks, transforming manual, error‑prone processes into streamlined, intelligent operations.
This article provides a comprehensive, hands‑on tutorial for deploying the open‑source Longhorn distributed block storage system on a Kubernetes cluster using Helm, covering prerequisites, Helm chart preparation, installation, validation, and PVC mounting to ensure reliable stateful workloads.
Coupang’s AI platform replaces costly data‑copy steps with a distributed cache that automatically pulls data from a central lake, boosts GPU utilization across regions, cuts storage and operational expenses, and speeds up model training by up to 40% while simplifying deployment via Kubernetes.
This article shares Anthropic’s SRE engineer insights on 23 actionable practices—from schema migration and Karpenter node management to OpenTelemetry adoption, Helm chart storage, and Terraform versus CloudFormation—offering concrete recommendations for building reliable, cost‑effective AI and cloud‑native platforms.
This article explains how to build a flexible machine‑learning infrastructure on Alibaba Cloud ACK using Ray and KubeRay, covering Ray's core components, AI libraries, deployment options on VMs and Kubernetes, code examples for data processing, model serving, and advanced scheduling and quota management techniques.
Starting with Kubernetes v1.33, the Alpha feature ContainerStopSignals introduces a Pod‑level lifecycle.stopSignal field that lets platform teams specify which Unix signal (e.g., SIGINT, SIGUSR1) should be sent to containers on termination, overcoming the previous reliance on image‑defined STOPSIGNAL and improving graceful shutdown control across Linux and Windows workloads.
The article discusses why token transmission is discouraged in microservice authentication, proposes passing explicit parameters, compares Feign, Dubbo, and Spring Boot Web internal call approaches, and explains how to integrate these patterns with a unified gateway, regular authentication modules, and Kubernetes Ingress for scalable backend architectures.
