spring-actuator

What problem does it solve?

This Skill solves the operational risk of running Spring Boot services without consistent health checks, production-ready observability, and properly secured /actuator endpoints for monitoring platforms and Kubernetes.

Core Features & Use Cases

• Production-grade Actuator configuration: Configure actuator base path, endpoint exposure (health/info/metrics/prometheus/loggers/env), and safe defaults like hiding health details and env values.
• Kubernetes liveness/readiness integration: Enable liveness/readiness probes and wire them to /actuator/health/liveness and /actuator/health/readiness so traffic routing reflects real readiness.
• Security for operational endpoints: Add a dedicated SecurityFilterChain for /actuator/** with role-based access and network/IP restrictions for sensitive endpoints.
• Custom health indicators and info: Implement HealthIndicator beans and enrich /actuator/info using build metadata for faster troubleshooting.
• Metrics tagging and observability: Standardize metric tags using application name and environment, and publish business/technical health signals.

Quick Start

Configure your Spring Boot application so Kubernetes probes and monitoring can safely access /actuator/health, metrics, and Prometheus while keeping actuator values and endpoints properly restricted.
