Learn five practical Dockerfile techniques—minimizing layers, using .dockerignore, multi‑stage builds, pinning base image versions, and adding HEALTHCHECK—to create smaller, faster, more secure containers, illustrated with real‑world examples and step‑by‑step commands for senior‑level efficiency.
This guide explains why Docker is essential for Java developers and provides step‑by‑step best practices—including selecting the right base image, using multi‑stage builds, environment variables, health checks, Docker cache, .dockerignore files, and image labels—complete with ready‑to‑use Dockerfile examples for Spring Boot projects.
This article demonstrates how to achieve zero‑downtime releases for SpringBoot applications on Kubernetes by configuring readiness/liveness probes, rolling update strategies, graceful shutdown hooks, horizontal pod autoscaling, Prometheus monitoring, and externalized configuration via ConfigMaps.
The article chronicles Ximalaya's journey from early Docker-based Java project templates to a mature Kubernetes-driven container platform, detailing development principles, health‑check strategies, deployment workflows, middleware integration, and lessons learned about scaling, automation, and collaborative engineering.
This guide explains Docker’s built‑in health‑check feature, covering process‑level checks, Dockerfile HEALTHCHECK syntax, runtime options with docker run, and health‑check configuration in docker‑compose, complete with practical examples and troubleshooting tips.
This guide explains how Kubernetes uses livenessProbe and readinessProbe to monitor container health, prevent traffic loss, and trigger restarts, covering probe types, implementation methods, configuration parameters, and practical examples with exec, HTTP GET, and TCP socket actions.
