Tutorial: Deploying a Production StatefulSet on Kubernetes with Argo CD and AWS EBS

·2 views

A technical guide published on DEV Community walks through deploying a production-grade Kubernetes StatefulSet using Argo CD for GitOps-based continuous delivery. The setup covers a restaurant application running three replicas on Amazon EKS, with each pod backed by a dedicated AWS EBS gp3 volume provisioned via the EBS CSI driver. Key Kubernetes resources configured include a headless service for stable pod network identities, a ConfigMap, a ServiceAccount, a StorageClass, and a PodDisruptionBudget requiring at least two pods to remain available during disruptions. The project follows a structured GitOps repository layout, with all manifests managed through Kustomize and synced to the cluster via an Argo CD Application resource. The guide emphasizes production best practices such as encrypted persistent storage, rolling update strategy, resource limits, and liveness and readiness probes.

Spring Boot Microservices: Sync Calls, Events, and AI Integration Explained

A technical guide explores how microservices built with Spring Boot can communicate effectively as applications grow in complexity. The article covers key tools including Spring Cloud OpenFeign, Service Discovery via Netflix Eureka, and Spring Cloud LoadBalancer for managing inter-service calls. It highlights why hardcoding service addresses is problematic and how logical service names resolve infrastructure coupling issues. The guide also addresses asynchronous processing, webhooks, and event-driven patterns to avoid blocking HTTP connections during long-running tasks. A real-world SaaS use case is presented, where an AI layer is isolated from the main backend using these architectural approaches.

Developer Shares C# Unit Testing Approach for School Sports Registration System

A developer has shared a set of C# unit tests built for a school sports registration system using xUnit and Moq frameworks. The tests cover model validation, ensuring that missing fields like Season and Sport are correctly flagged as invalid. Service-layer tests verify that the fee calculation logic returns accurate amounts for different season and sport combinations. Controller tests use a mock service to confirm that invalid form submissions re-render the view without calling the service, while valid submissions trigger the service and redirect to a success page. The example serves as a practical introduction to layered unit testing in ASP.NET Core MVC applications.

Testing Claude Code skill argument substitution across 12 runs reveals key behaviors

A developer ran 12 controlled tests on Claude Code version 2.1.278 on September 22, 2026, to observe exactly how argument placeholders behave inside skill bodies. Results showed that $ARGUMENTS always preserved the raw input string including quotes, while positional variables like $0 and $1 used shell-style splitting with quotes stripped. Missing positional arguments were left as literal text rather than replaced with empty values, and the argument-hint setting had no effect on what the skill body actually received. One notable finding was that bare environment-style tokens like $HOME, when passed as arguments, disappeared from positional slots but remained visible in $ARGUMENTS. The author built dedicated echo-skills to capture substituted content directly from session transcripts, noting that in one of 12 runs the model's reply did not match the actual substituted text — highlighting the value of reading raw transcripts over trusting model output.

AeroCI Tool Lets Developers Test GitHub Actions Workflows Locally Before Pushing

A developer has built AeroCI, an open-source command-line tool designed to act as a local twin for GitHub Actions workflows, reducing the repetitive push-fail-debug cycle. AeroCI executes real shell commands and injects standard GITHUB_* environment variables, rather than simulating a successful run, and explicitly flags steps it cannot reproduce locally. The tool provides commands to initialize configuration, validate workflow structure, and run jobs in isolated environments — each job and matrix combination gets its own copy of the project directory to better mirror real CI runner isolation. An analysis mode can detect dead or duplicated steps, unused outputs, and generate a workflow complexity score. Secrets are kept out of job sandboxes by default and exposed only through a dedicated secrets context.
