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.
Index ¶
Constants ¶
const ( Integer = "integer" Number = "number" String = "string" Boolean = "boolean" )
Defines openapi types.
const PrintColumnsKey = "x-kubernetes-print-columns"

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 ¶
func (a *Array) Accept(v SchemaVisitor)
type BaseSchema ¶
BaseSchema holds data used by each types of schema.
func (*BaseSchema) GetDescription ¶
func (b *BaseSchema) GetDescription() string
func (*BaseSchema) GetExtensions ¶
func (b *BaseSchema) GetExtensions() map[string]interface{}
func (*BaseSchema) GetPath ¶
func (b *BaseSchema) GetPath() *Path
type Definitions ¶
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 ¶
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 ¶
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 ¶
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 ¶
func (k *Kind) Accept(v SchemaVisitor)
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 ¶
func (m *Map) Accept(v SchemaVisitor)
type Path ¶
type Path struct {
// contains filtered or unexported fields
}
Path helps us keep track of type paths
type Primitive ¶
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 ¶
func (p *Primitive) Accept(v SchemaVisitor)
type Ref ¶
type Ref struct { BaseSchema // contains filtered or unexported fields }
func (*Ref) Accept ¶
func (r *Ref) Accept(v SchemaVisitor)
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 ¶
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 ¶
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.
