What criteria does this skill use to evaluate Docker readiness?

It evaluates configurations based on 11 key criteria including health checks, signal handling (STOPSIGNAL), logging to stdout/stderr, OPcache optimization, non-root user usage, and resource limits.

Can this skill identify security risks?

Yes, it specifically checks for the use of non-root users and the exclusion of development dependencies, which are critical for reducing the attack surface of your containers.

How do I interpret the production readiness score?

A score of 90-100 is considered Production Ready. 70-89 needs improvement, and anything below 70 is considered not ready for stable production environments.

Is this tool only for PHP applications?

While the core checklist is specifically optimized for PHP (checking OPcache and PHP-FPM), many of the architectural checks like health checks and resource limits are applicable to any containerized application.

Deployment & DevOps

Audits and optimizes Docker configurations for PHP applications to ensure high-performance, secure, and production-ready deployments.

The Docker Production Readiness Checker provides a systematic audit of your container environment, specifically tailored for PHP applications. It evaluates Dockerfiles and Compose configurations against an industry-standard checklist including health checks, graceful shutdowns, logging practices, and security hardening. By generating a weighted score and detailed report, this skill helps developers identify critical gaps in their infrastructure, such as missing resource limits or improper signal handling, ensuring that applications are robust enough for high-traffic production environments.
