会被剪裁成：
json:
spec:
foo: abc
bar: def
status:
something: x
这意味着指定的
spec
对象的
something
字段会被剪裁（因为“
spec
”有定义），
但是其他部分不会。
status
没有定义，所以
status.__something__
都没有被
剪裁。
9.3.4 IntOrString
和
RawExtensions
在有些情况下，结构化的
Schema
的描述能力还不够。比如某个多态字段
的类型可能会发生变化。比如我们在原生
Kubernetes API
类型中见到过的
IntOrString
类型。
在
CRD
中，也可以通过在
Schema
中声明
x-kubernetes-int-or-string:
true
后在
CRD
中使用
IntOrString
。类似地，还可通过声明
x-kubernetes-
embedded-object: true
来使用
runtime.RawExtensions
。
比如：
type: object
properties:
intorstr:
type: object
x-kubernetes-int-or-string: true
embedded:
x-kubernetes-embedded-object: true
x-kubernetes-preserve-unknown-fields: true
这就声明了：
• intorstr
字段的类型可以是整型，也可以是字符串
