<p>I am trying to use "autoscaling/v2beta2" apiVersion in my configuration following <a href="https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale-walkthrough/#autoscaling-on-multiple-metrics-and-custom-metrics" rel="nofollow noreferrer">this tutorial</a>. And also I am on Google Kubernetes Engine.</p>

<p>However I get this error:</p>

<p><code>error: unable to recognize "backend-hpa.yaml": no matches for kind "HorizontalPodAutoscaler" in version "autoscaling/v2beta2"</code></p>

<p>When I list the available api-versions:</p>

<pre><code>$ kubectl api-versions

admissionregistration.k8s.io/v1beta1
apiextensions.k8s.io/v1beta1

</code></pre>

<p>So indeed I am missing autoscaling/v2beta2.</p>

<p>Then I check my kubernetes version:</p>

<pre><code>$ kubectl version

Client Version: version.Info{Major:"1", Minor:"13", GitVersion:"v1.13.6", GitCommit:"abdda3f9fefa29172298a2e42f5102e777a8ec25", GitTreeState:"clean", BuildDate:"2019-05-08T13:53:53Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13+", GitVersion:"v1.13.6-gke.13", GitCommit:"fcbc1d20b6bca1936c0317743055ac75aef608ce", GitTreeState:"clean", BuildDate:"2019-06-19T20:50:07Z", GoVersion:"go1.11.5b4", Compiler:"gc", Platform:"linux/amd64"}
</code></pre>

<p>So it looks like I have a version of 1.13.6. Supposedly autoscaling/v2beta2 is available since 1.12.</p>

<p>So why it is not available for me?</p>

<p>Unfortunaltely HPA autoscaling API v2beta2 is not available on GKE yet. It can be freely used with Kubeadm and Minikube.</p>
