Overview

Package runtime defines conversions between generic types and structs to map query strings to struct objects.

Package runtime includes helper functions for working with API objects that follow the kubernetes API object conventions, which are:

0. Your API objects have a common metadata struct member, TypeMeta.

1. Your code refers to an internal set of API objects.

2. In a separate package, you have an external set of API objects.

3. The external set is considered to be versioned, and no breaking changes are ever made to it (fields may be added but not changed or removed).

4. As your api evolves, you'll make an additional versioned package with every major change.

5. Versioned packages have conversion functions which convert to and from the internal version.

6. You'll continue to support older versions according to your deprecation policy, and you can easily provide a program/library to update old versions into new versions because of 5.

7. All of your serializations and deserializations are handled in a centralized place.

Package runtime provides a conversion helper to make 5 easy, and the Encode/Decode/DecodeInto trio to accomplish 7. You can also register additional "codecs" which use a version of your choice. It's recommended that you register your types with runtime in your package's init function.

As a bonus, a few common types useful from all api objects and versions are provided in types.go.

Types

type Codec 

type Codec Serializer

func NewCodec 

func NewCodec(e Encoder, d Decoder) Codec

NewCodec creates a Codec from an Encoder and Decoder.

type Decoder 

type Decoder interface {
	// Decode attempts to deserialize the provided data using either the innate typing of the scheme or the
	// default kind, group, and version provided. It returns a decoded object as well as the kind, group, and
	// version from the serialized data, or an error. If into is non-nil, it will be used as the target type
	// and implementations may choose to use it rather than reallocating an object. However, the object is not
	// guaranteed to be populated. The returned object is not guaranteed to match into. If defaults are
	// provided, they are applied to the data by default. If no defaults or partial defaults are provided, the
	// type of the into may be used to guide conversion decisions.
	Decode(data []byte, defaults *schema.GroupVersionKind, into Object) (Object, *schema.GroupVersionKind, error)
}

Decoder attempts to load an object from data.

type Encoder

	// incompatible, or if no conversion is defined.
	Encode(obj Object, w io.Writer) error
}

Encoder writes objects to a serialized form

type EquivalentResourceMapper 

type EquivalentResourceMapper interface {
	// EquivalentResourcesFor returns a list of resources that address the same underlying data as resource.
	// If subresource is specified, only equivalent resources which also have the same subresource are included.
	// The specified resource can be included in the returned list.
	EquivalentResourcesFor(resource schema.GroupVersionResource, subresource string) []schema.GroupVersionResource
	// KindFor returns the kind expected by the specified resource[/subresource].

FieldLabelConversionFunc converts a field selector to internal representation.

type Framer 

type Framer interface {
	NewFrameReader(r io.ReadCloser) io.ReadCloser
	NewFrameWriter(w io.Writer) io.Writer
}

Framer is a factory for creating readers and writers that obey a particular framing pattern.

type GroupVersioner 

type GroupVersioner interface {
	// KindForGroupVersionKinds returns a desired target group version kind for the given input, or returns ok false if no
	// target is known. In general, if the return target is not in the input list, the caller is expected to invoke
	// Scheme.New(target) and then perform a conversion between the current Go type and the destination Go type.
	// Sophisticated implementations may use additional information about the input kinds to pick a destination kind.
	KindForGroupVersionKinds(kinds []schema.GroupVersionKind) (target schema.GroupVersionKind, ok bool)
}

GroupVersioner refines a set of possible conversion targets into a single option. 

var (

gv=mygroup/__internal, groupKinds=mygroup, anothergroup
KindForGroupVersionKinds(yetanother/v1/Baz, anothergroup/v1/Bar) -> mygroup/__internal/Bar (matched preferred group)

gv=mygroup/__internal, groupKinds=mygroup, anothergroup
KindForGroupVersionKinds(yetanother/v1/Baz, yetanother/v1/Bar) -> mygroup/__internal/Baz (no preferred group/kind match, uses first kind in list)

func NewMultiGroupVersioner 

func NewMultiGroupVersioner(gv schema.GroupVersion, groupKinds ...schema.GroupKind) GroupVersioner

NewMultiGroupVersioner returns the provided group version for any kind that matches one of the provided group kinds. Kind may be empty in the provided group kind, in which case any kind will match.

func (GroupVersioners) KindForGroupVersionKinds 

func (gvs GroupVersioners) KindForGroupVersionKinds(kinds []schema.GroupVersionKind) (schema.GroupVersionKind, bool)

KindForGroupVersionKinds returns the first match of any of the group versioners, or false if no match occurred.

type KubeTypes 

type KubeTypes []Pair

KubeTypes is an array to represent all available types in a parsed file. [0] is for the type itself

func ParseDocumentationFrom 

func ParseDocumentationFrom(src string) []KubeTypes

ParseDocumentationFrom gets all types' documentation and returns them as an array. Each type is again represented as an array (we have to use arrays as we need to be sure for the order of the fields). This function returns fields and struct definitions that have no documentation as {name, ""}.

	// serializer are in the provided group version.
	EncoderForVersion(serializer Encoder, gv GroupVersioner) Encoder
	// DecoderForVersion returns a decoder that ensures objects being read by the provided
	// serializer are in the provided group version by default.
	DecoderToVersion(serializer Decoder, gv GroupVersioner) Decoder
}

NegotiatedSerializer is an interface used for obtaining encoders, decoders, and serializers for multiple supported media types. This would commonly be accepted by a server component that performs HTTP content negotiation to accept multiple formats.

type NestedObjectDecoder 

type NestedObjectDecoder interface {
	DecodeNestedObjects(d Decoder) error
}

NestedObjectDecoder is an optional interface that objects may implement to be given an opportunity to decode any nested Objects / RawExtensions during serialization.

type Object 

type Object interface {
	GetObjectKind() schema.ObjectKind
	DeepCopyObject() Object
}

Object interface must be supported by all API types registered with Scheme. Since objects in a scheme are expected to be serialized to the wire, the interface an Object must provide to the Scheme allows serializers to set the kind, version, and group the object is represented as. An Object may choose to return a no-op ObjectKindAccessor in cases where it is not expected to be serialized.

func Decode 

func Decode(d Decoder, data []byte) (Object, error)

Decode is a convenience wrapper for decoding data into an Object.

func NewEncodable 

func NewEncodable(e Encoder, obj Object, versions ...schema.GroupVersion) Object

func NewEncodableList 

func NewEncodableList(e Encoder, objects []Object, versions ...schema.GroupVersion) []Object

NewEncodableList creates an object that will be encoded with the provided codec on demand. Provided as a convenience for test cases dealing with internal objects.

func UseOrCreateObject 

func UseOrCreateObject(t ObjectTyper, c ObjectCreater, gvk schema.GroupVersionKind, obj Object) (Object, error)

UseOrCreateObject returns obj if the canonical ObjectKind returned by the provided typer matches gvk, or invokes the ObjectCreator to instantiate a new gvk. Returns an error if the typer cannot find the object.

type ObjectConvertor 

type ObjectConvertor interface {
	// Convert attempts to convert one object into another, or returns an error. This
	// method does not mutate the in object, but the in and out object might share data structures,
	// i.e. the out object cannot be mutated without mutating the in object as well.
	// The context argument will be passed to all nested conversions.
	Convert(in, out, context interface{}) error
	// ConvertToVersion takes the provided object and converts it the provided version. This
	// method does not mutate the in object, but the in and out object might share data structures,
	// i.e. the out object cannot be mutated without mutating the in object as well.
	// This method is similar to Convert() but handles specific details of choosing the correct
	// output version.
	ConvertToVersion(in Object, gv GroupVersioner) (out Object, err error)
	ConvertFieldLabel(gvk schema.GroupVersionKind, label, value string) (string, string, error)
}

ObjectConvertor converts an object to a different version.

func UnsafeObjectConvertor 

func UnsafeObjectConvertor(scheme *Scheme) ObjectConvertor

UnsafeObjectConvertor performs object conversion without copying the object structure, for use when the converted object will not be reused or mutated. Primarily for use within versioned codecs, which use the external object for serialization but do not return it.

type ObjectCreater

	New(kind schema.GroupVersionKind) (out Object, err error)
}

ObjectCreater contains methods for instantiating an object by kind and version.

	// Default takes an object (must be a pointer) and applies any default values.
	// Defaulters may not error.
	Default(in Object)
}

type ObjectTyper 

type ObjectTyper interface {
	// ObjectKinds returns the all possible group,version,kind of the provided object, true if
	// the object is unversioned, or an error if the object is not recognized
	// (IsNotRegisteredError will return true).
	ObjectKinds(Object) ([]schema.GroupVersionKind, bool, error)
	// Recognizes returns true if the scheme is able to handle the provided version and kind,
	// or more precisely that the provided version is a possible conversion or decoding
	// target.
	Recognizes(gvk schema.GroupVersionKind) bool
}

ObjectTyper contains methods for extracting the APIVersion and Kind of objects.

type ObjectVersioner 

type ObjectVersioner interface {
	ConvertToVersion(in Object, gv GroupVersioner) (out Object, err error)
}

type Pair 

type Pair struct {
	Name, Doc string
}

Pair of strings. We keed the name of fields and the doc

type ParameterCodec 

type ParameterCodec interface {
	// DecodeParameters takes the given url.Values in the specified group version and decodes them
	// into the provided object, or returns an error.
	DecodeParameters(parameters url.Values, from schema.GroupVersion, into Object) error
	// EncodeParameters encodes the provided object as query parameters or returns an error.
	EncodeParameters(obj Object, to schema.GroupVersion) (url.Values, error)
}

ParameterCodec defines methods for serializing and deserializing API objects to url.Values and performing any necessary conversion. Unlike the normal Codec, query parameters are not self describing and the desired version must be specified.

func NewParameterCodec 

func NewParameterCodec(scheme *Scheme) ParameterCodec

type ProtobufMarshaller 

type ProtobufMarshaller interface {
	MarshalTo(data []byte) (int, error)
}

type ProtobufReverseMarshaller 

type ProtobufReverseMarshaller interface {
	MarshalToSizedBuffer(data []byte) (int, error)
}

type RawExtension 

type RawExtension struct {
	// Raw is the underlying serialization of this object.
	//
	// TODO: Determine how to detect ContentType and ContentEncoding of 'Raw' data.
	Raw []byte `json:"-" protobuf:"bytes,1,opt,name=raw"`
	// Object can hold a representation of this extension - useful for working with versioned
	// structs.
	Object Object `json:"-"`
}

RawExtension is used to hold extensions in external versions.

To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

// Internal package: 

type MyAPIObject struct {
	runtime.TypeMeta `json:",inline"`
	MyPlugin runtime.Object `json:"myPlugin"`
}

type PluginA struct {
	AOption string `json:"aOption"`
}

// External package: 

type MyAPIObject struct {
	runtime.TypeMeta `json:",inline"`
	MyPlugin runtime.RawExtension `json:"myPlugin"`
}

type PluginA struct {
	AOption string `json:"aOption"`
}

// On the wire, the JSON will look something like this: 

{
	"kind":"MyAPIObject",
	"apiVersion":"v1",
	"myPlugin": {
		"kind":"PluginA",
		"aOption":"foo",
	},
}

So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)

	ResourceVersion(obj Object) (string, error)
}

ResourceVersioner provides methods for setting and retrieving the resource version from an API object.

type Scheme 

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

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.

In a Scheme, a Type is a particular Go struct, a Version is a point-in-time identifier for a particular representation of that Type (typically backwards compatible), a Kind is the unique name for that Type within the Version, and a Group identifies a set of Versions, Kinds, and Types that evolve over time. An Unversioned Type is one that is not yet formally bound to a type and is promised to be backwards compatible (effectively a "v1" of a Type that does not expect to break in the future).

Schemes are not expected to change at runtime and are only threadsafe after registration is complete.

func NewScheme 

func NewScheme() *Scheme

NewScheme creates a new Scheme. This scheme is pluggable by default.

func (*Scheme) AddConversionFunc 

func (s *Scheme) AddConversionFunc(a, b interface{}, fn conversion.ConversionFunc) error

AddConversionFunc registers a function that converts between a and b by passing objects of those types to the provided function. The function *must* accept objects of a and b - this machinery will not enforce any other guarantee.

func (*Scheme) AddConversionFuncs 

func (s *Scheme) AddConversionFuncs(conversionFuncs ...interface{}) error

AddConversionFuncs adds functions to the list of conversion functions. The given functions should know how to convert between two of your API objects, or their sub-objects. We deduce how to call these functions from the types of their two parameters; see the comment for Converter.Register.

Note that, if you need to copy sub-objects that didn't change, you can use the conversion.Scope object that will be passed to your conversion function. Additionally, all conversions started by Scheme will set the SrcVersion and DestVersion fields on the Meta object. Example:

s.AddConversionFuncs( 

func(in *InternalObject, out *ExternalObject, scope conversion.Scope) error {
	// You can depend on Meta() being non-nil, and this being set to
	// the source version, e.g., ""
	s.Meta().SrcVersion
	// You can depend on this being set to the destination version,
	// e.g., "v1".
	s.Meta().DestVersion
	// Call scope.Convert to copy sub-fields.
	s.Convert(&in.SubFieldThatMoved, &out.NewLocation.NewName, 0)
	return nil
},

)

(For more detail about conversion functions, see Converter.Register's comment.)

Also note that the default behavior, if you don't add a conversion function, is to sanely copy fields that have the same names and same type names. It's OK if the destination type has extra fields, but it must not remove any. So you only need to add conversion functions for things with changed/removed fields.

func (*Scheme) AddFieldLabelConversionFunc 

func (s *Scheme) AddFieldLabelConversionFunc(gvk schema.GroupVersionKind, conversionFunc FieldLabelConversionFunc) error

AddFieldLabelConversionFunc adds a conversion function to convert field selectors of the given kind from the given version to internal version representation.

func (*Scheme) AddGeneratedConversionFunc 

func (s *Scheme) AddGeneratedConversionFunc(a, b interface{}, fn conversion.ConversionFunc) error

AddGeneratedConversionFunc registers a function that converts between a and b by passing objects of those types to the provided function. The function *must* accept objects of a and b - this machinery will not enforce any other guarantee.

func (*Scheme) AddIgnoredConversionType 

func (s *Scheme) AddIgnoredConversionType(from, to interface{}) error

AddIgnoredConversionType identifies a pair of types that should be skipped by conversion (because the data inside them is explicitly dropped during conversion).

func (*Scheme) AddKnownTypeWithName 

func (s *Scheme) AddKnownTypeWithName(gvk schema.GroupVersionKind, obj Object)

AddKnownTypeWithName is like AddKnownTypes, but it lets you specify what this type should be encoded as. Useful for testing when you don't want to make multiple packages to define your structs. Version may not be empty - use the APIVersionInternal constant if you have a type that does not have a formal version.

func (*Scheme) AddKnownTypes 

func (s *Scheme) AddKnownTypes(gv schema.GroupVersion, types ...Object)

AddKnownTypes registers all types passed in 'types' as being members of version 'version'. All objects passed to types should be pointers to structs. The name that go reports for the struct becomes the "kind" field when encoding. Version may not be empty - use the APIVersionInternal constant if you have a type that does not have a formal version.

func (*Scheme) AddTypeDefaultingFunc 

func (s *Scheme) AddTypeDefaultingFunc(srcType Object, fn func(interface{}))

AddTypeDefaultingFunc registers a function that is passed a pointer to an object and can default fields on the object. These functions will be invoked when Default() is called. The function will never be called unless the defaulted object matches srcType. If this function is invoked twice with the same srcType, the fn passed to the later call will be used instead.

func (*Scheme) AddUnversionedTypes 

func (s *Scheme) AddUnversionedTypes(version schema.GroupVersion, types ...Object)

AddUnversionedTypes registers the provided types as "unversioned", which means that they follow special rules. Whenever an object of this type is serialized, it is serialized with the provided group version and is not converted. Thus unversioned objects are expected to remain backwards compatible forever, as if they were in an API group and version that would never be updated.

TODO: there is discussion about removing unversioned and replacing it with objects that are manifest into 

every version with particular schemas. Resolve this method at that point.

func (*Scheme) AllKnownTypes 

func (s *Scheme) AllKnownTypes() map[schema.GroupVersionKind]reflect.Type

AllKnownTypes returns the all known types.

func (*Scheme) Convert 

func (s *Scheme) Convert(in, out interface{}, context interface{}) error

Convert will attempt to convert in into out. Both must be pointers. For easy testing of conversion functions. Returns an error if the conversion isn't possible. You can call this with types that haven't been registered (for example, a to test conversion of types that are nested within registered types). The context interface is passed to the convertor. Convert also supports Unstructured types and will convert them intelligently.

func (*Scheme) ConvertFieldLabel 

func (s *Scheme) ConvertFieldLabel(gvk schema.GroupVersionKind, label, value string) (string, string, error)

ConvertFieldLabel alters the given field label and value for an kind field selector from versioned representation to an unversioned one or returns an error.

func (*Scheme) ConvertToVersion 

func (s *Scheme) ConvertToVersion(in Object, target GroupVersioner) (Object, error)

ConvertToVersion attempts to convert an input object to its matching Kind in another version within this scheme. Will return an error if the provided version does not contain the inKind (or a mapping by name defined with AddKnownTypeWithName). Will also return an error if the conversion does not result in a valid Object being returned. Passes target down to the conversion methods as the Context on the scope.

func (*Scheme) ObjectKinds 

func (s *Scheme) ObjectKinds(obj Object) ([]schema.GroupVersionKind, bool, error)

ObjectKinds returns all possible group,version,kind of the go object, true if the object is considered unversioned, or an error if it's not a pointer or is unregistered.

func (*Scheme) PreferredVersionAllGroups 

func (s *Scheme) PreferredVersionAllGroups() []schema.GroupVersion

PreferredVersionAllGroups returns the most preferred version for every group. group ordering is random.

func (*Scheme) PrioritizedVersionsAllGroups

func (*Scheme) RegisterInputDefaults 

func (s *Scheme) RegisterInputDefaults(in interface{}, fn conversion.FieldMappingFunc, defaultFlags conversion.FieldMatchingFlags) error

RegisterInputDefaults sets the provided field mapping function and field matching as the defaults for the provided input type. The fn may be nil, in which case no mapping will happen by default. Use this method to register a mechanism for handling a specific input type in conversion, such as a map[string]string to structs.

func (*Scheme) SetVersionPriority 

func (s *Scheme) SetVersionPriority(versions ...schema.GroupVersion) error

SetVersionPriority allows specifying a precise order of priority. All specified versions must be in the same group, and the specified order overwrites any previously specified order for this group

func (*Scheme) UnsafeConvertToVersion 

func (s *Scheme) UnsafeConvertToVersion(in Object, target GroupVersioner) (Object, error)

UnsafeConvertToVersion will convert in to the provided target if such a conversion is possible, but does not guarantee the output object does not share fields with the input object. It attempts to be as efficient as possible when doing conversion.

type SchemeBuilder 

type SchemeBuilder []func(*Scheme) error

SchemeBuilder collects functions that add things to a scheme. It's to allow code to compile without explicitly referencing generated types. You should declare one in each package that will have generated deep copy or conversion functions.

func NewSchemeBuilder

NewSchemeBuilder calls Register for you.

func (*SchemeBuilder) AddToScheme 

func (sb *SchemeBuilder) AddToScheme(s *Scheme) error

type Serializer 

type Serializer interface {
	Encoder
	Decoder
}

Serializer is the core interface for transforming objects into a serialized format and back. Implementations may choose to perform conversion of the object, but no assumptions should be made.

func NewBase64Serializer

	MediaTypeType string
	// MediaTypeSubType is the second part of the MediaType ("json" in "application/json").
	MediaTypeSubType string
	// EncodesAsText indicates this serializer can be encoded to UTF-8 safely.
	EncodesAsText bool
	// Serializer is the individual object serializer for this media type.
	Serializer Serializer
	// PrettySerializer, if set, can serialize this object in a form biased towards
	// readability.
	PrettySerializer Serializer
	// StreamSerializer, if set, describes the streaming serialization format
	// for this media type.
	StreamSerializer *StreamSerializerInfo
}

SerializerInfo contains information about a specific serialization format

func SerializerInfoForMediaType 

func SerializerInfoForMediaType(types []SerializerInfo, mediaType string) (SerializerInfo, bool)

SerializerInfoForMediaType returns the first info in types that has a matching media type (which cannot include media-type parameters), or the first info with an empty media type, or false if no type matches.

type StorageSerializer 

type StorageSerializer interface {
	// SupportedMediaTypes are the media types supported for reading and writing objects.

	// DecoderForVersion returns a decoder that ensures objects being read by the provided
	// serializer are in the provided group version by default.
	DecoderToVersion(serializer Decoder, gv GroupVersioner) Decoder
}

type StreamSerializerInfo 

type StreamSerializerInfo struct {
	// EncodesAsText indicates this serializer can be encoded to UTF-8 safely.
	EncodesAsText bool
	// Serializer is the top level object serializer for this type when streaming

	// +optional
	Kind string `json:"kind,omitempty" yaml:"kind,omitempty" protobuf:"bytes,2,opt,name=kind"`
}

TypeMeta is shared by all top level objects. The proper way to use it is to inline it in your type, like this: 

type MyAwesomeAPIObject struct {
     runtime.TypeMeta    `json:",inline"`
     ... // other fields
}

func (obj *MyAwesomeAPIObject) SetGroupVersionKind(gvk *metav1.GroupVersionKind) { metav1.UpdateTypeMeta(obj,gvk) }; GroupVersionKind() *GroupVersionKind

TypeMeta is provided here for convenience. You may use it directly from this package or define your own with the same fields.

	// with a registered type. Most likely, nothing should be done with this
	// except for passing it through the system.
	Raw []byte `protobuf:"bytes,2,opt,name=raw"`
	// ContentEncoding is encoding used to encode 'Raw' data.
	// Unspecified means no encoding.

	// ContentType  is serialization method used to serialize 'Raw'.
	// Unspecified means ContentTypeJSON.
	ContentType string `protobuf:"bytes,4,opt,name=contentType"`
}

Unknown allows api objects with unknown types to be passed-through. This can be used to deal with the API objects from a plug-in. Unknown objects still have functioning TypeMeta features-- kind, version, etc. TODO: Make this object have easy access to field based accessors and settors for metadata and field mutatation.
