Function GetAutoGrowFromSpec

internal/util/volumes.go:115–137

GetAutoGrowFromSpec extracts AutoGrow settings from the provided AutoGrowSpec. It returns two strings: (trigger, maxGrow). - trigger: the auto-grow threshold as a decimal percentage string (e.g., "75"). Defaults to "75" when no trigger is configured. - maxGrow: the maximum growth size as a whole nu

(spec *v1beta1.VolumeClaimSpecWithAutoGrow)

// maxGrow empty. When set, Trigger is formatted as a base-10 string and MaxGrow is
// converted from a resource quantity (bytes) to mebibytes by dividing bytes by 1024*1024.
func GetAutoGrowFromSpec(spec *v1beta1.VolumeClaimSpecWithAutoGrow) (string, string) {
	// MaxGrow is optional; an empty string means "no limit" on growth and the volume
	// will grow by 50% each time it is triggered.
	maxGrow := ""

	// We always want to set default trigger; We will override it if
	// the user has set a different value.
	trigger := AutoGrowTriggerDefault

	// If AutoGrow is configured on the VolumeClaimSpecWithAutoGrow, extract
	// the Trigger and MaxGrow values
	if spec != nil && spec.AutoGrow != nil {
