Trait Composition

How PHP K8s uses traits to compose resource functionality.

Overview

PHP K8s uses trait-based composition instead of deep inheritance hierarchies. This allows resources to mix and match functionality as needed.

Pattern

class K8sPod extends K8sResource
{
    use HasSpec;
    use HasStatus;
    use HasMetadata;
    use HasSelector;

    // Resource-specific methods
}

Available Traits

See Resource Traits for complete list.

Benefits

• Flexibility - Resources only include traits they need
• Reusability - Traits can be used across different resources
• Maintainability - Changes to traits affect all resources using them
• No Diamond Problem - Avoid multiple inheritance issues
