Functions

func CreateTwoWayMergePatch

func CreateTwoWayMergePatch(orig, new, dataStruct interface{}) ([]byte, bool, error)

CreateTwoWayMergePatch is a helper to construct a two-way merge patch from objects (instead of bytes)

func GetLastAppliedConfigAnnotation

func GetLastAppliedConfigAnnotation(live *unstructured.Unstructured) *unstructured.Unstructured

func HideSecretData

func HideSecretData(target *unstructured.Unstructured, live *unstructured.Unstructured) (*unstructured.Unstructured, *unstructured.Unstructured, error)

HideSecretData replaces secret data values in specified target, live secrets and in last applied configuration of live secret with stars. Also preserves differences between target, live and last applied config values. E.g. if all three are equal the values would be replaced with same number of stars. If all the are different then number of stars in replacement should be different.

func Normalize

func Normalize(un *unstructured.Unstructured, normalizer Normalizer)

func NormalizeSecret

func NormalizeSecret(un *unstructured.Unstructured)

NormalizeSecret mutates the supplied object and encodes stringData to data, and converts nils to empty strings. If the object is not a secret, or is an invalid secret, then returns the same object.

Types

type DiffResult

type DiffResult struct {
	Diff     gojsondiff.Diff
	Modified bool
}

func Diff

func Diff(config, live *unstructured.Unstructured, normalizer Normalizer) *DiffResult

Diff performs a diff on two unstructured objects. If the live object happens to have a "kubectl.kubernetes.io/last-applied-configuration", then perform a three way diff.

func ThreeWayDiff

func ThreeWayDiff(orig, config, live *unstructured.Unstructured) (*DiffResult, error)

ThreeWayDiff performs a diff with the understanding of how to incorporate the last-applied-configuration annotation in the diff. Inputs are assumed to be stripped of type information

func TwoWayDiff

func TwoWayDiff(config, live *unstructured.Unstructured) *DiffResult

TwoWayDiff performs a normal two-way diff between two unstructured objects. Ignores extra fields in the live object. Inputs are assumed to be stripped of type information

func (*DiffResult) ASCIIFormat

func (d *DiffResult) ASCIIFormat(left *unstructured.Unstructured, formatOpts formatter.AsciiFormatterConfig) (string, error)

ASCIIFormat returns the ASCII format of the diff

func (*DiffResult) JSONFormat

func (d *DiffResult) JSONFormat() (string, error)

JSONFormat returns the diff as a JSON string

type DiffResultList

type DiffResultList struct {
	Diffs    []DiffResult
	Modified bool
}

func DiffArray

func DiffArray(configArray, liveArray []*unstructured.Unstructured, normalizer Normalizer) (*DiffResultList, error)

DiffArray performs a diff on a list of unstructured objects. Objects are expected to match environments

type Normalizer

type Normalizer interface {
	Normalize(un *unstructured.Unstructured) error
}
