kubectl apply ingress: 未知字段错误

Question

我的入口是：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: mongoexpress-ingress
spec:
  rules:
  - host: mylocalmongoexpress.com
    http:
      paths:
      - backend:
          serviceName: mongoexpress-service
          servicePort: 8081

当我运行 'kubectl apply -f mongoexpress-ingress.yaml' 时，我得到错误：

error: error validating "mongoexpress-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, ValidationError(Ingress.spec.rules[0].http.paths[0]): missing required field "pathType" in io.k8s.api.networking.v1.HTTPIngressPath]; if you choose to ignore these errors, turn validation off with --validate=false

通过在线资源，我找不到 yaml 文件中的问题。

那么我在这里错过了什么？

Answer 1

您似乎混用了 Ingress 版本。您声明了 networking.k8s.io/v1, but your block of YAML corresponds to networking.k8s.io/v1beta1 - 从 1.22.

起不再可用

v1beta1

- backend:
    serviceName: mongoexpress-service
    servicePort: 8081

v1

- backend:
    service:
      name: mongoexpress-service
      port:
        number: 8081

Answer 2

入口规范 has changed 从 v1beta1 到 v1。尝试：

...
spec:
  rules:
  - host: mylocalmongoexpress.com
     http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: mongoexpress-service
            port:
              number: 8081

Answer 3

作为其他答案的补充，在这种情况下，您始终可以使用 kubectl explain，如果您尝试这样做：kubectl explain ingress.spec.rules.http.paths.backend.service --api-version=networking.k8s.io/v1 那么您将得到：

FIELDS:
   name <string> -required-
     Name is the referenced service. The service must exist in the same
     namespace as the Ingress object.

   port <Object>
     Port of the referenced service. A port name or port number is required for
     a IngressServiceBackend.

通过这种方式，您可以轻松找到哪些字段可用于哪个 API 版本的哪个资源。
