Fix CRD OpenAPI schema
fixes#65243
depends on https://github.com/kubernetes/kube-openapi/pull/84
without this PR, kubectl complains about creating this CRD with a validation schema (which worked in 1.10):
```yaml
apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
name: resources.mygroup.example.com
spec:
group: mygroup.example.com
version: v1alpha1
scope: Namespaced
names:
plural: resources
singular: resource
kind: Kind
listKind: KindList
validation:
openAPIV3Schema:
properties:
spec:
type: array
items:
type: number
```
> error: error validating "/Users/jliggitt/projects/snippets/crd/crd.yaml": error validating data: [ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): unknown field "type" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray, ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): missing required field "Schema" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray, ValidationError(CustomResourceDefinition.spec.validation.openAPIV3Schema.properties.spec.items): missing required field "JSONSchemas" in io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray]; if you choose to ignore these errors, turn validation off with --validate=false
that is because the types used to serialize JSONSchema require custom marshaling/unmarshaling, and the OpenAPI generator was not informed of that, so it produced this:
```json
{
"io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaPropsOrArray": {
"description": "JSONSchemaPropsOrArray represents a value that can either be a JSONSchemaProps or an array of JSONSchemaProps. Mainly here for serialization purposes.",
"required": [
"Schema",
"JSONSchemas"
],
"properties": {
"JSONSchemas": {
"type": "array",
"items": {
"$ref": "#/definitions/io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaProps"
}
},
"Schema": {
"$ref": "#/definitions/io.k8s.apiextensions-apiserver.pkg.apis.apiextensions.v1beta1.JSONSchemaProps"
}
}
}
}
```
OpenAPI isn't able to represent oneOf/anyOf types correctly currently. Until it can, we definitely shouldn't publish a schema containing required fields which aren't even part of the JSON serialization. This PR implements custom openapi type functions, which omit the properties/required/schema attributes for four specific JSONSchema types. This allows kubectl to continue creating these objects without complaining.
