Functions ¶
func Compile ¶
func Compile( apiConversion *apisv1alpha1.APIConversion, structuralSchemas map[string]*structuralschema.Structural, ) (map[string][]*CompiledRule, error)
Compile compiles conversion rules.
Types ¶
type CRConverterFactory ¶
type CRConverterFactory struct {
// contains filtered or unexported fields
}
CRConverterFactory instantiates converters that are capable of converting custom resources between different API versions. It supports CEL-based conversion rules from APIConversion resources and the "none" conversion strategy.
func NewCRConverterFactory ¶
func NewCRConverterFactory( apiConversionInformer apisinformers.APIConversionClusterInformer, objectCELTransformationsTimeout time.Duration, ) *CRConverterFactory
NewCRConverterFactory returns a CRConverterFactory that supports APIConversion-based conversions and the "none" conversion strategy.
func (*CRConverterFactory) NewConverter ¶
func (f *CRConverterFactory) NewConverter(crd *apiextensionsv1.CustomResourceDefinition) (conversion.CRConverter, error)
NewConverter returns the appropriate conversion.Converter based on the CRD. If the CRD identifies as for a "wildcard partial metadata request", the nop converter is used. Otherwise, it returns a CEL-based converter if there is an associated APIConversion, a nop converter if the strategy is "none", or an error otherwise.
type CompiledRule ¶
type CompiledRule struct {
// FromPath is an expression specifying the field in the source version, such as spec.firstName.
FromPath string
// FromFields is FromPath split by '.', with any leading '.' removed.
FromFields []string
// ToPath is an expression specifying the destination field in the target version, such as spec.name.first.
ToPath string
// ToFields is ToPath split by '.', with any leading '.' removed.
ToFields []string
// Program is a compiled set of instructions for a conversion transformation.
Program cel.Program
}
CompiledRule contains the compiled cel.Program to convert a single field.
type Converter ¶
type Converter struct {
// contains filtered or unexported fields
}
func NewConverter ¶
func NewConverter( crd *apiextensionsv1.CustomResourceDefinition, apiConversion *apisv1alpha1.APIConversion, objectCELTransformationsTimeout time.Duration, ) (*Converter, error)
func (*Converter) Convert ¶
func (c *Converter) Convert(list *unstructured.UnstructuredList, targetGV schema.GroupVersion) (*unstructured.UnstructuredList, error)
