Constants

const (

	// DefaultImageTag is the default tag for docker image.
	DefaultImageTag = "latest"

	// Name is the name of the plugin used in the plugin registry and configurations.
	Name = "ImageLocality"
)

The two thresholds are used as bounds for the image score range. They correspond to a reasonable size range for container images compressed and stored in registries; 90%ile of images on dockerhub drops into this range.
