# Generate OpenAPI definitions
|
|
|
|
- To generate definition for a specific type or package add "+k8s:openapi-gen=true" tag to the type/package comment lines.
|
|
- To exclude a type or a member from a tagged package/type, add "+k8s:openapi-gen=false" tag to the comment lines.
|
|
|
|
# OpenAPI Extensions
|
|
OpenAPI spec can have extensions on types. To define one or more extensions on a type or its member
|
|
add `+k8s:openapi-gen=x-kubernetes-$NAME:`$VALUE`` to the comment lines before type/member. A type/member can
|
|
have multiple extensions. The rest of the line in the comment will be used as $VALUE so there is no need to
|
|
escape or quote the value string. Extensions can be used to pass more information to client generators or
|
|
documentation generators. For example a type might have a friendly name to be displayed in documentation or
|
|
being used in a client's fluent interface.
|
|
|
|
# Custom OpenAPI type definitions
|
|
|
|
Custom types which otherwise don't map directly to OpenAPI can override their
|
|
OpenAPI definition by implementing a function named "OpenAPIDefinition" with
|
|
the following signature:
|
|
|
|
import openapi "k8s.io/kube-openapi/pkg/common"
|
|
|
|
// ...
|
|
|
|
type Time struct {
|
|
time.Time
|
|
}
|
|
|
|
func (_ Time) OpenAPIDefinition() openapi.OpenAPIDefinition {
|
|
return openapi.OpenAPIDefinition{
|
|
Schema: spec.Schema{
|
|
SchemaProps: spec.SchemaProps{
|
|
Type: []string{"string"},
|
|
Format: "date-time",
|
|
},
|
|
},
|
|
}
|
|
}
|
|
|
|
Alternatively, the type can avoid the "openapi" import by defining the following
|
|
methods. The following example produces the same OpenAPI definition as the
|
|
example above:
|
|
|
|
func (_ Time) OpenAPISchemaType() []string { return []string{"string"} }
|
|
func (_ Time) OpenAPISchemaFormat() string { return "date-time" }
|
|
|
|
TODO(mehdy): Make k8s:openapi-gen a parameter to the generator now that OpenAPI has its own repo.
