我正在尝试编写kubernetes crd验证模式。我有一个数组(vc)的结构,这些结构中的一个字段是必需的(name
字段)。
我尝试了查看各种示例,但当name
不存在时,它不会产生错误。有什么建议是错的吗?
vc:
type: array
items:
type: object
properties:
name:
type: string
address:
type: string
required:
- name

如果您使用的是v1.8,则需要启用CustomResourceValidation
功能门才能使用验证功能。这可以通过在kube-apiserver上使用以下标志来完成:
--feature-gates=CustomResourceValidation=true
这是它正常工作的一个示例(我在v1.12上对此进行了测试,但这也适用于早期版本):
CRD:
apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition
metadata:
name: foos.stable.example.com
spec:
group: stable.example.com
versions:
- name: v1
served: true
storage: true
version: v1
scope: Namespaced
names:
plural: foos
singular: foo
kind: Foo
validation:
openAPIV3Schema:
properties:
spec:
properties:
vc:
type: array
items:
type: object
properties:
name:
type: string
address:
type: string
required:
- name
自定义资源:
apiVersion: "stable.example.com/v1"
kind: Foo
metadata:
name: new-foo
spec:
vc:
- address: "bar"
kubectl create -f crd.yaml
customresourcedefinition.apiextensions.k8s.io/foos.stable.example.com created
kubectl get crd foos.stable.example.com -oyaml
kubectl create -f cr-validation.yaml
The Foo "new-foo" is invalid: []: Invalid value: map[string]interface {}{"metadata":map[string]interface {}{"creationTimestamp":"2018-11-18T19:45:23Z", "generation":1, "uid":"7d7f8f0b-eb6a-11e8-b861-54e1ad9de0be", "name":"new-foo", "namespace":"default"}, "spec":map[string]interface {}{"vc":[]interface {}{map[string]interface {}{"address":"bar"}}}, "apiVersion":"stable.example.com/v1", "kind":"Foo"}: validation failure list:
