# Yaml Config Validator

## Overview

This skill provides automated assistance for yaml config validator tasks within the DevOps Basics domain.

## When to Use

This skill activates automatically when you:
- Mention "yaml config validator" in your request
- Ask about yaml config validator patterns or best practices
- Need help with foundational devops skills covering version control, containerization, basic ci/cd, and infrastructure fundamentals.

## Instructions

1. Provides step-by-step guidance for yaml config validator
2. Follows industry best practices and patterns
3. Generates production-ready code and configurations
4. Validates outputs against common standards

## Examples

**Example: Basic Usage**
Request: "Help me with yaml config validator"
Result: Provides step-by-step guidance and generates appropriate configurations


## Prerequisites

- Relevant development environment configured
- Access to necessary tools and services
- Basic understanding of devops basics concepts


## Output

- Generated configurations and code
- Best practice recommendations
- Validation results


## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| Configuration invalid | Missing required fields | Check documentation for required parameters |
| Tool not found | Dependency not installed | Install required tools per prerequisites |
| Permission denied | Insufficient access | Verify credentials and permissions |


## Resources

Overview

This skill validates YAML configuration files and guides DevOps practitioners through common validation tasks. It delivers step-by-step checks, generates corrected snippets, and explains fixes so configurations meet production standards. It is designed for foundational DevOps workflows like CI/CD, container orchestration, and infrastructure as code.

How this skill works

The skill parses YAML, runs schema and style validations, and reports missing fields, type mismatches, and indentation or syntax errors. It can apply common schema rules (required keys, types, enums), suggest corrections, and output production-ready snippets. Validation results include actionable messages and remediation steps.

When to use it

When you need to verify YAML for CI/CD pipelines, Helm charts, or Kubernetes manifests
While authoring or reviewing configuration files to catch syntax and schema issues early
When onboarding new services or templates to enforce consistent configuration patterns
During automated pre-commit or CI checks to prevent invalid deploys
When converting informal requirements into validated configuration templates

Best practices

Define and maintain concise schemas (JSON Schema or OpenAPI) for all config types
Run validation in pre-commit hooks and CI pipelines to catch errors before merge
Use small, focused config files and import shared fragments to reduce duplication
Validate both syntax and semantic constraints (types, required fields, value ranges)
Provide clear, actionable validation messages and include sample corrected snippets

Example use cases

Validate Kubernetes manifests and report missing resource fields or wrong types
Lint Helm values.yaml and suggest default values or schema updates
Check CI pipeline YAML for common pitfalls like incorrect indentation or invalid steps
Auto-generate minimal valid YAML snippets for service onboarding from a provided schema
Integrate validation into pre-commit hooks or CI jobs to block invalid merges

FAQ

What kinds of YAML issues are detected?

Syntax errors, indentation problems, missing required keys, incorrect types, disallowed values, and simple semantic inconsistencies are detected and reported.

Can it enforce a custom schema?

Yes. Provide a JSON Schema or compatible specification and the validator will check config files against that schema and highlight violations.
