在Ryan Baxter的Spring On Kubernetes workshop之后，我遇到了无法解决的问题。在“部署到Kubernetes”的步骤中，生成depoyment.yaml和services.yaml文件后，我运行

kubectl apply -f ./k8s

我收到验证错误：

error validating "k8s/deployment.yaml": error validating data: the server could not find the requested resource; if you choose to ignore these errors,turn validation off with --validate=false
error validating "k8s/service.yaml": error validating data: the server could not find the requested resource; if you choose to ignore these errors,turn validation off with --validate=false 

运行后

kubectl apply -f ./k8s --validate = false

我知道

error: unable to recognize "k8s/deployment.yaml": no matches for extensions/,Kind=Deployment
service"my-app" created

这是yaml文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: my-app
  name: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: my-app
    spec:
      containers:
      - image: docker.io/my-id/my-app
        name: my-app
        resources: {}
status: {}

根据Harsh的建议，我将apiVersion更改为apps / v1，然后再次运行kubectl apply命令。

deployment "my-app" created
service "my-app" configured    

根据手表显示的内容，我跑步

kubectl port-forward svc/my-app 8080:80 

手表中显示svc / my-app的位置。它产生

error: invalid resource name svc/my-app: [may not contain '/']       

要清理，我运行

kubectl delete -f ./k8s

它产生

service "my-app" deleted
Error from server (NotFound): error when stopping "k8s/deployment.yaml": the server could not find the requested resource

我不知道这些问题是由我的操作错误还是某些错误引起的。
