Functions

func CoreOperations added in v0.2.0 

func CoreOperations(data []byte) ([]runtime.Object, []string, error)

The "core operations" is important to Kedge as it unmarshals, validates the artifacts as well as return the correct transformation of said artifact.

Returns the converted Kubernetes objects, extra resources and an error, if any.

func GetScheme added in v0.2.0 

func GetScheme() (*runtime.Scheme, error)

GetScheme() returns runtime.Scheme with supported Kubernetes API resource definitions which Kedge supports right now. The core v1 scheme is first initialized and then other controllers' scheme is added to that scheme, e.g. batch/v1 scheme is added to add support for Jobs controller to the v1 Scheme. Also, (from upstream) Scheme defines methods for serializing and deserializing API objects, a type registry for converting group, version, and kind information to and from Go schemas, and mappings between Go schemas of different versions. A scheme is the foundation for a versioned API and versioned configuration over time.

func PrettyPrintObjects added in v0.10.0 

func PrettyPrintObjects(v interface{}) string

func SetGVK added in v0.2.0 

func SetGVK(runtimeObject runtime.Object, scheme *runtime.Scheme) error

SetGVK() sets Group, Version and Kind for the generated Kubernetes resources. This takes in a generated Kubernetes API resource's runtime object and runtime scheme based on which the GVK will be set.
