sac*_*boy 3 kubernetes kubernetes-custom-resources
我正在尝试编写 kubernetes crd 验证架构。我有一个结构数组 (vc),这些结构中的一个字段是必需的(name
字段)。
我尝试查看各种示例,但当name
不存在时它不会生成错误。有什么建议有什么问题吗?
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

这是一个它的工作示例(我在 v1.12 上测试了这个,但这也应该适用于早期版本):
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:

自定义资源:
apiVersion: "stable.example.com/v1"
kind: Foo
metadata:
name: new-foo
spec:
vc:
- address: "bar"
