在 Kubernetes Ingress 从 v1beta1切换到 v1时，在 io.k8s.api.networking.v1.IngresBackend 中获取错误“未知字段“ serviceName”

我有下面的 YAML 为我的进度和它的工作(并继续工作) :

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: test-ingress
namespace: test-layer
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: mylocalhost.com
http:
paths:
- path: /
backend:
serviceName: test-app
servicePort: 5000

但是，它告诉我它已经过时，我应该改用 networking.k8s.io/v1。当我这样做时(见下文) ，它会抛出一个错误。

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: test-ingress
namespace: test-layer
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: mylocalhost.com
http:
paths:
- path: /
backend:
serviceName: test-app
servicePort: 5000

错误

error: error validating "test-ingress.yaml":
error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend):
unknown field "serviceName" in io.k8s.api.networking.v1.IngressBackend,
ValidationError(Ingress.spec.rules[0].http.paths[0].backend):
unknown field "servicePort" in io.k8s.api.networking.v1.IngressBackend];
if you choose to ignore these errors, turn validation off with --validate=false

除了改变 API 版本之外，我没有做任何其他的改变。

最佳答案

我认为这个公关包含了你所要求的改变。

`Ingress` and `IngressClass` resources have graduated to `networking.k8s.io/v1`. Ingress and IngressClass types in the `extensions/v1beta1` and `networking.k8s.io/v1beta1` API versions are deprecated and will no longer be served in 1.22+. Persisted objects can be accessed via the `networking.k8s.io/v1` API. Notable changes in v1 Ingress objects (v1beta1 field names are unchanged):
* `spec.backend` -> `spec.defaultBackend`
* `serviceName` -> `service.name`
* `servicePort` -> `service.port.name` (for string values)
* `servicePort` -> `service.port.number` (for numeric values)
* `pathType` no longer has a default value in v1; "Exact", "Prefix", or "ImplementationSpecific" must be specified
Other Ingress API updates:
* backends can now be resource or service backends
* `path` is no longer required to be a valid regular expression

如果查看 1.19进入文件，看起来新的语法应该是:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: minimal-ingress
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
spec:
rules:
- http:
paths:
- path: /testpath
pathType: Prefix
backend:
service:
name: test
port:
number: 80

不幸的是，我没有1.19集群来测试我自己，但是我想这就是你要碰到的。
