type TappHashInterface ¶
type TappHashInterface interface {
// SetTemplateHash sets PodTemplateSpec's hash value into template's labels,
// returns true if needs set and is set, otherwise false
SetTemplateHash(template *corev1.PodTemplateSpec) bool
// GetTemplateHash returns PodTemplateSpec's hash value, the values is stored in labels.
GetTemplateHash(labels map[string]string) string
// SetUniqHash sets hash value of PodTemplateSpec(without container images) into template's labels,
// returns true if needs set and is set, otherwise false
SetUniqHash(template *corev1.PodTemplateSpec) bool
// GetUniqHash returns hash value of PodTemplateSpec(without container images), the values is stored in labels.
GetUniqHash(labels map[string]string) string
// HashLabels returns labels key that stores TemplateHash and UniqHash
HashLabels() []string
}
TappHashInterface is used for generate and verify hash for tapp.
