pkg/validator/kind

This package provides validation functionality for Kind cluster configurations.

Purpose

Contains validation logic specifically for Kind cluster configurations. This validator ensures Kind configurations are valid according to Kind APIs and requirements before cluster provisioning.

Features

• Kind Configuration Validation: Validates Kind cluster configurations using upstream Kind APIs
• Node Configuration Validation: Validates node configurations and resource requirements
• Metadata Validation: Integrates with metadata validator for consistent validation
• Port Mapping Validation: Validates port mappings and network configurations
• Pre-provisioning Validation: Catches configuration errors before attempting cluster creation

Usage

import "github.com/devantler-tech/ksail-go/pkg/validator/kind"

// Create Kind validator
validator := kind.NewValidator()

// Validate Kind cluster configuration
result := validator.Validate(kindConfig)
if !result.Valid {
    for _, err := range result.Errors {
        fmt.Printf("Validation error: %v\n", err)
    }
}

Key Components

• validator.go: Core Kind validation logic and implementation
• Kind API integration: Uses upstream Kind APIs for validation
• metadata validation: Leverages shared metadata validation utilities

Integration

This validator is used by:

• pkg/config-manager/kind: Kind configuration loading and validation
• Kind cluster provisioning workflows
• CLI commands that work with Kind configurations

Validation Rules

The Kind validator enforces:

• Valid Kind cluster naming conventions
• Proper node configurations and resource limits
• Valid port mapping and network configurations
• Kubernetes version compatibility
• Container image and registry configurations
• Volume mount path validation
• CNI and networking plugin configurations

This ensures Kind configurations are valid before attempting local cluster provisioning with Docker.
