Overview

Package openapi is a collection of libraries for fetching the openapi spec from a Kubernetes server and then indexing the type definitions. The openapi spec contains the object model definitions and extensions metadata such as the patchStrategy and patchMergeKey for creating patches.

Functions

func GetPrintColumns

func GetPrintColumns(extensions spec.Extensions) (string, bool)

GetPrintColumns looks for the open API extension for the display columns.

Types

type Array

type Array struct {
	BaseSchema

	SubType Schema
}

Array must have all its element of the same `SubType`.

func (*Array) Accept added in v1.8.0

func (a *Array) Accept(v SchemaVisitor)

func (*Array) GetName added in v1.8.0

func (a *Array) GetName() string

type BaseSchema added in v1.8.0

type BaseSchema struct {
	Description string
	Extensions  map[string]interface{}

	Path Path
}

BaseSchema holds data used by each types of schema.

func (*BaseSchema) GetDescription added in v1.8.0

func (b *BaseSchema) GetDescription() string

func (*BaseSchema) GetExtensions added in v1.8.0

func (b *BaseSchema) GetExtensions() map[string]interface{}

func (*BaseSchema) GetPath added in v1.8.0

func (b *BaseSchema) GetPath() *Path

type Definitions added in v1.8.0

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

Definitions is an implementation of `Resources`. It looks for resources in an openapi Schema.

func (*Definitions) LookupResource added in v1.8.0

func (d *Definitions) LookupResource(gvk schema.GroupVersionKind) Schema

LookupResource is public through the interface of Resources. It returns a visitable schema from the given group-version-kind.

func (*Definitions) ParseSchema added in v1.8.0

func (d *Definitions) ParseSchema(s *openapi_v2.Schema, path *Path) (Schema, error)

ParseSchema creates a walkable Schema from an openapi schema. While this function is public, it doesn't leak through the interface.

type Getter

type Getter interface {
	// OpenAPIData returns the parsed OpenAPIData
	Get() (Resources, error)
}

Getter is an interface for fetching openapi specs and parsing them into an Resources struct

func NewOpenAPIGetter

func NewOpenAPIGetter(openAPIClient discovery.OpenAPISchemaInterface) Getter

NewOpenAPIGetter returns an object to return OpenAPIDatas which reads from a server, and then stores in memory for subsequent invocations

type Kind

type Kind struct {
	BaseSchema

	// Lists names of required fields.
	RequiredFields []string
	// Maps field names to types.
	Fields map[string]Schema
}

Kind is a complex object. It can have multiple different subtypes for each field, as defined in the `Fields` field. Mandatory fields are listed in `RequiredFields`. The key of the object is always of type `string`.

func (*Kind) Accept added in v1.8.0

func (k *Kind) Accept(v SchemaVisitor)

func (*Kind) GetName added in v1.8.0

func (k *Kind) GetName() string

type Map

type Map struct {
	BaseSchema

	SubType Schema
}

Map is an object who values must all be of the same `SubType`. The key of the object is always of type `string`.

func (*Map) Accept added in v1.8.0

func (m *Map) Accept(v SchemaVisitor)

func (*Map) GetName added in v1.8.0

func (m *Map) GetName() string

type Path added in v1.8.0

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

Path helps us keep track of type paths

func NewPath added in v1.8.0

func NewPath(key string) Path

func (*Path) ArrayPath added in v1.8.0

func (p *Path) ArrayPath(i int) Path

ArrayPath appends an array index and creates a new path

func (*Path) FieldPath added in v1.8.0

func (p *Path) FieldPath(field string) Path

FieldPath appends a field name and creates a new path

func (*Path) Get added in v1.8.0

func (p *Path) Get() []string

func (*Path) Len added in v1.8.0

func (p *Path) Len() int

func (*Path) String added in v1.8.0

func (p *Path) String() string

type Primitive added in v1.8.0

type Primitive struct {
	BaseSchema

	// Type of a primitive must be one of: integer, number, string, boolean.
	Type   string
	Format string
}

Primitive is a literal. There can be multiple types of primitives, and this subtype can be visited through the `subType` field.

func (*Primitive) Accept added in v1.8.0

func (p *Primitive) Accept(v SchemaVisitor)

func (*Primitive) GetName added in v1.8.0

func (p *Primitive) GetName() string

type Ref added in v1.8.0

type Ref struct {
	BaseSchema
	// contains filtered or unexported fields
}

func (*Ref) Accept added in v1.8.0

func (r *Ref) Accept(v SchemaVisitor)

func (*Ref) GetName added in v1.8.0

func (r *Ref) GetName() string

func (*Ref) Reference added in v1.8.0

func (r *Ref) Reference() string

func (*Ref) SubSchema added in v1.8.0

func (r *Ref) SubSchema() Schema

type Reference added in v1.8.0

type Reference interface {
	Schema

	Reference() string
	SubSchema() Schema
}

Reference implementation depends on the type of document.

type Resources

type Resources interface {
	LookupResource(gvk schema.GroupVersionKind) Schema
}

Resources interface describe a resources provider, that can give you resource based on group-version-kind.

func NewOpenAPIData

func NewOpenAPIData(doc *openapi_v2.Document) (Resources, error)

NewOpenAPIData creates a new `Resources` out of the openapi document.

type Schema added in v1.8.0

type Schema interface {
	// Giving a visitor here will let you visit the actual type.
	Accept(SchemaVisitor)

	// Pretty print the name of the type.
	GetName() string
	// Describes how to access this field.
	GetPath() *Path
	// Describes the field.
	GetDescription() string
	// Returns type extensions.
	GetExtensions() map[string]interface{}
}

Schema is the base definition of an openapi type.

type SchemaVisitor added in v1.8.0

type SchemaVisitor interface {
	VisitArray(*Array)
	VisitMap(*Map)
	VisitPrimitive(*Primitive)
	VisitKind(*Kind)
	VisitReference(Reference)
}

SchemaVisitor is an interface that you need to implement if you want to "visit" an openapi schema. A dispatch on the Schema type will call the appropriate function based on its actual type: - Array is a list of one and only one given subtype - Map is a map of string to one and only one given subtype - Primitive can be string, integer, number and boolean. - Kind is an object with specific fields mapping to specific types. - Reference is a link to another definition.
