Docker Configuration Validator

This one checks your Dockerfiles and Docker Compose files for best practices, security issues, and modern syntax compliance. Pull it in when you're prepping configs for production, setting up CI/CD validation, or auditing multi-stage builds. It's passed audits from Gen Agent Trust Hub, Socket, and Snyk, which is reassuring for a security-focused tool. The workflow appears structured around phased assessment, though the details are truncated in the docs. Useful if you want an automated second opinion on Docker configs before they hit prod, especially if you're working in a team where Docker knowledge varies.

Core Workflow

Phase 1: Initial Assessment

When a user requests Docker validation, start by understanding the scope:

Identify What to Validate
- Single Dockerfile or multiple?
- Docker Compose file(s)?
- Entire project directory?
- Specific concerns or focus areas?
- Production vs development environment?
Understand Requirements
- Security compliance level needed?
- Multi-stage build requirement?
- Performance constraints?
- CI/CD integration needed?
- Automated validation script desired?
