func ValidateStructural ¶
func ValidateStructural(s *Structural, fldPath *field.Path) field.ErrorList
ValidateStructural checks that s is a structural schema with the invariants:
* structurality: both `ForbiddenGenerics` and `ForbiddenExtensions` only have zero values, with the two exceptions for IntOrString. * RawExtension: for every schema with `x-kubernetes-embedded-resource: true`, `x-kubernetes-preserve-unknown-fields: true` and `type: object` are set * IntOrString: for `x-kubernetes-int-or-string: true` either `type` is empty under `anyOf` and `allOf` or the schema structure is one of these:
- anyOf: - type: integer - type: string
- allOf: - anyOf: - type: integer - type: string - ... zero or more
* every specified field or array in s is also specified outside of value validation. * metadata at the root can only restrict the name and generateName, and not be specified at all in nested contexts. * additionalProperties at the root is not allowed.
Types ¶
type Extensions ¶
type Extensions struct {
// x-kubernetes-preserve-unknown-fields stops the API server
// decoding step from pruning fields which are not specified
// in the validation schema. This affects fields recursively,
// but switches back to normal pruning behaviour if nested
// properties or additionalProperties are specified in the schema.
// False means that the pruning behaviour is inherited from the parent.
// False does not mean to activate pruning.
XPreserveUnknownFields bool
// x-kubernetes-embedded-resource defines that the value is an
// embedded Kubernetes runtime.Object, with TypeMeta and
// ObjectMeta. The type must be object. It is allowed to further
// restrict the embedded object. Both ObjectMeta and TypeMeta
// are validated automatically. x-kubernetes-preserve-unknown-fields
// must be true.
XEmbeddedResource bool
// x-kubernetes-int-or-string specifies that this value is
// either an integer or a string. If this is true, an empty
// type is allowed and type as child of anyOf is permitted
// if following one of the following patterns:
//
// 1) anyOf:
// - type: integer
// - type: string
// 2) allOf:
// - anyOf:
// - type: integer
// - type: string
// - ... zero or more
XIntOrString bool
}
Extensions contains the Kubernetes OpenAPI v3 vendor extensions.
func (*Extensions) DeepCopy ¶
func (in *Extensions) DeepCopy() *Extensions
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Extensions.
func (*Extensions) DeepCopyInto ¶
func (in *Extensions) DeepCopyInto(out *Extensions)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
type Generic ¶
type Generic struct {
Description string
// type specifies the type of a value.
// It can be object, array, number, integer, boolean, string.
// It is optional only if x-kubernetes-preserve-unknown-fields
// or x-kubernetes-int-or-string is true.
Type string
Title string
Default JSON
AdditionalProperties *StructuralOrBool
Nullable bool
}
Generic contains the generic schema fields not allowed in value validation.
func (*Generic) DeepCopy ¶
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Generic.
func (*Generic) DeepCopyInto ¶
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
type JSON ¶
type JSON struct {
Object interface{}
}
JSON wraps an arbitrary JSON value to be able to implement deepcopy.
func (JSON) DeepCopyInto ¶
DeepCopyInto creates a deep copy of the wrapped JSON value and stores it in into.
type NestedValueValidation ¶
type NestedValueValidation struct {
ValueValidation
Items *NestedValueValidation
Properties map[string]NestedValueValidation
// Anything set in the following will make the scheme
// non-structural, with the exception of these two patterns if
// x-kubernetes-int-or-string is true:
//
// 1) anyOf:
// - type: integer
// - type: string
// 2) allOf:
// - anyOf:
// - type: integer
// - type: string
// - ... zero or more
ForbiddenGenerics Generic
ForbiddenExtensions Extensions
}
NestedValueValidation contains value validations, items and properties usable when nested under a logical junctor, and catch all structs for generic and vendor extensions schema fields.
func (*NestedValueValidation) DeepCopy ¶
func (in *NestedValueValidation) DeepCopy() *NestedValueValidation
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new NestedValueValidation.
func (*NestedValueValidation) DeepCopyInto ¶
func (in *NestedValueValidation) DeepCopyInto(out *NestedValueValidation)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
type Structural ¶
type Structural struct {
Items *Structural
Properties map[string]Structural
Generic
Extensions
ValueValidation *ValueValidation
}
Structural represents a structural schema.
func NewStructural ¶
func NewStructural(s *apiextensions.JSONSchemaProps) (*Structural, error)
NewStructural converts an OpenAPI v3 schema into a structural schema. A pre-validated JSONSchemaProps will not fail on NewStructural. This means that we require that:
- items is not an array of schemas - the following fields are not set:
- id
- schema
- $ref
- patternProperties
- dependencies
- additionalItems
- definitions.
The follow fields are not preserved: - externalDocs - example.
func (*Structural) DeepCopy ¶
func (in *Structural) DeepCopy() *Structural
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Structural.
func (*Structural) DeepCopyInto ¶
func (in *Structural) DeepCopyInto(out *Structural)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
func (*Structural) ToGoOpenAPI ¶
func (s *Structural) ToGoOpenAPI() *spec.Schema
ToGoOpenAPI converts a structural schema to go-openapi schema. It is faithful and roundtrippable with the exception of `nullable:true` for empty type (`type:""`).
WARNING: Do not use the returned schema to perform CRD validation until this restriction is solved.
Nullable:true is mapped to `type:[<structural-type>,"null"]` if the structural type is non-empty, and nullable is dropped if the structural type is empty.
func (*Structural) Unfold ¶
func (s *Structural) Unfold() *Structural
Unfold expands vendor extensions of a structural schema. It mutates the receiver.
type StructuralOrBool ¶
type StructuralOrBool struct {
Structural *Structural
Bool bool
}
StructuralOrBool is either a structural schema or a boolean.
func (*StructuralOrBool) DeepCopy ¶
func (in *StructuralOrBool) DeepCopy() *StructuralOrBool
DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new StructuralOrBool.
func (*StructuralOrBool) DeepCopyInto ¶
func (in *StructuralOrBool) DeepCopyInto(out *StructuralOrBool)
DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.
type ValueValidation ¶
type ValueValidation struct {
Format string
Maximum *float64
ExclusiveMaximum bool
Minimum *float64
ExclusiveMinimum bool
MaxLength *int64
MinLength *int64
Pattern string
MaxItems *int64
MinItems *int64
UniqueItems bool
MultipleOf *float64
Enum []JSON
MaxProperties *int64
MinProperties *int64
Required []string
AllOf []NestedValueValidation
OneOf []NestedValueValidation
AnyOf []NestedValueValidation
Not *NestedValueValidation
}
ValueValidation contains all schema fields not contributing to the structure of the schema.
func (*ValueValidation) DeepCopy ¶
func (in *ValueValidation) DeepCopy() *ValueValidation

type Visitor ¶
type Visitor struct {
// Structural is called on each Structural node in the schema, before recursing into
// the subtrees. It is allowed to mutate s. Return true if something has been changed.
// +optional
Structural func(s *Structural) bool
// NestedValueValidation is called on each NestedValueValidation node in the schema,
// before recursing into subtrees. It is allowed to mutate vv. Return true if something
// has been changed.
