title: Kubernetes create deployment unexpected SchemaError
body: <p>I'm following that tutorial (<a href="https://www.baeldung.com/spring-boot-minikube" rel="noreferrer">https://www.baeldung.com/spring-boot-minikube</a>)
  I want to create Kubernetes deployment in yaml file (simple-crud-dpl.yaml):</p>
  
  <pre><code>apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: simple-crud
  spec:
    selector:
        matchLabels:
          app: simple-crud
    replicas: 3
    template:
      metadata:
        labels:
          app: simple-crud
      spec:
        containers:
          - name: simple-crud
            image: simple-crud:latest
            imagePullPolicy: Never
            ports:
              - containerPort: 8080
  </code></pre>
  
  <p>but when I run <code>kubectl create -f simple-crud-dpl.yaml</code> i got:
  <code>error: SchemaError(io.k8s.api.autoscaling.v2beta2.MetricTarget): invalid object doesn't have additional properties</code></p>
  
  <p>I'm using the newest version of kubectl: </p>
  
  <pre><code>kubectl version
  Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.11", GitCommit:"637c7e288581ee40ab4ca210618a89a555b6e7e9", GitTreeState:"clean", BuildDate:"2018-11-26T14:38:32Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"darwin/amd64"}

  </code></pre>
  
  <p>I'm also using minikube locally as it's described in tutorial. Everything is working till deployment and service. I'm not able to do it.</p>
