type Checker ¶

type Checker interface {
	// Check evaluates the checker's condition and returns the result.
	// Called frequently during scheduler operations.
	Check() Result
}

Checker evaluates a condition and returns whether a package should be enabled.

Examples of checkers:

• Version checker: Validates Kubernetes/Deckhouse version against constraints
• Condition checker: Evaluates boolean conditions (e.g., bootstrap ready)
• Custom checkers: Any domain-specific requirements

type Result ¶

type Result struct {
	Enabled bool   `json:"enabled"`
	Reason  string `json:"reason,omitempty"`
	Message string `json:"message,omitempty"`
}

Result represents the outcome of a checker evaluation.
