Constants

const LastAppliedConfig = "banzaicloud.com/last-applied"

Variables

var DefaultAnnotator = NewAnnotator(LastAppliedConfig)

var DefaultPatchMaker = NewPatchMaker(DefaultAnnotator, &K8sStrategicMergePatcher{}, &BaseJSONMergePatcher{})

Functions

func DeleteNullInJson

func DeleteNullInJson(jsonBytes []byte) ([]byte, map[string]interface{}, error)

Types

type Annotator

type Annotator struct {
	// contains filtered or unexported fields
}

func NewAnnotator

func NewAnnotator(key string) *Annotator

func (*Annotator) GetModifiedConfiguration

func (a *Annotator) GetModifiedConfiguration(obj runtime.Object, annotate bool) ([]byte, error)

GetModifiedConfiguration retrieves the modified configuration of the object. If annotate is true, it embeds the result as an annotation in the modified configuration. If an object was read from the command input, it will use that version of the object. Otherwise, it will use the version from the server.

func (*Annotator) GetOriginalConfiguration

func (a *Annotator) GetOriginalConfiguration(obj runtime.Object) ([]byte, error)

GetOriginalConfiguration retrieves the original configuration of the object from the annotation, or nil if no annotation was found.

func (*Annotator) SetLastAppliedAnnotation

func (a *Annotator) SetLastAppliedAnnotation(obj runtime.Object) error

SetLastAppliedAnnotation gets the modified configuration of the object, without embedding it again, and then sets it on the object as the annotation.

func (*Annotator) SetOriginalConfiguration

func (a *Annotator) SetOriginalConfiguration(obj runtime.Object, original []byte) error

SetOriginalConfiguration sets the original configuration of the object as the annotation on the object for later use in computing a three way patch.

type BaseJSONMergePatcher

type BaseJSONMergePatcher struct{}

func (*BaseJSONMergePatcher) CreateMergePatch

func (p *BaseJSONMergePatcher) CreateMergePatch(originalJSON, modifiedJSON []byte) ([]byte, error)

func (*BaseJSONMergePatcher) CreateThreeWayJSONMergePatch

func (p *BaseJSONMergePatcher) CreateThreeWayJSONMergePatch(original, modified, current []byte) ([]byte, error)

func (*BaseJSONMergePatcher) MergePatch

func (p *BaseJSONMergePatcher) MergePatch(docData, patchData []byte) ([]byte, error)

type CalculateOption

type CalculateOption func([]byte, []byte) ([]byte, []byte, error)

func IgnoreField

func IgnoreField(field string) CalculateOption

func IgnoreStatusFields

func IgnoreStatusFields() CalculateOption

func IgnoreVolumeClaimTemplateTypeMetaAndStatus
