Does this skill support non-PHP Docker Compose files?

While optimized for PHP stacks (detecting specific patterns like php-fpm health checks), the core logic for networking, security, and resource limits applies to any standard Docker Compose configuration.

How does it detect hardcoded passwords?

It uses specialized grep patterns to scan for password-related environment variables containing plain-text values instead of secure variable interpolation from .env files.

Why is the 'depends_on' condition check important?

Without the 'service_healthy' condition, containers might start before their dependencies (like databases) are actually ready to accept connections, leading to avoidable application crashes.

Can it fix the issues automatically?

The skill identifies issues and provides corrected configuration snippets that Claude can use to immediately refactor and improve your docker-compose.yml file.

Deployment & DevOps

Validates and optimizes Docker Compose configurations for PHP application stacks to ensure security, reliability, and performance.

The Docker Compose Configuration Checker is a specialized tool for Claude Code designed to audit and refine PHP-based container orchestration files. It scans for critical issues such as hardcoded credentials, missing health checks, and improper service dependencies that lead to race conditions during startup. By providing automated detection for deprecated syntax, resource limit omissions, and network isolation gaps, this skill helps developers build production-ready, resilient Docker environments aligned with modern DevOps best practices and PHP architecture standards.

Key Features

01Validates network isolation and port binding configurations for enhanced security

02Flags deprecated Docker Compose versions and missing restart policies

03Analyzes resource limits to prevent OOM errors and resource exhaustion

04Identifies missing or misconfigured service health checks and startup dependencies

0545 GitHub stars

06Detects hardcoded passwords and sensitive credentials in environment variables

Use Cases

01Standardizing Docker configurations across multiple PHP microservices or team projects

02Troubleshooting intermittent startup failures caused by race conditions in container orchestration

03Hardening PHP application infrastructure before deploying to production environments
