Why is a specific health check needed for PHP-FPM?

Standard container checks often miss dead worker processes; using specific tools like php-fpm-healthcheck or cgi-fcgi ensures the PHP engine is actually capable of processing requests.

How does it distinguish between minor and critical issues?

It uses a severity classification system where missing checks for core services are 'Critical', while suboptimal timing parameters are labeled as 'Minor'.

Can this skill help with database startup race conditions?

Yes, it identifies missing 'depends_on' conditions and 'start_period' parameters that often cause applications to crash before the database is fully initialized.

Deployment & DevOps

Audits and optimizes Docker health check configurations for PHP application stacks to ensure high availability and reliable service discovery.

The Docker Health Check Configuration Checker is a specialized skill for Claude Code designed to identify and fix container health monitoring issues in PHP-based environments. It automatically analyzes Dockerfiles and docker-compose.yml files to verify health check patterns for PHP-FPM, Nginx, MySQL, PostgreSQL, Redis, and RabbitMQ. By enforcing best practices for intervals, timeouts, and start periods, this skill prevents common pitfalls like startup race conditions and undetected worker failures, ensuring a more resilient production infrastructure.
