如何在Kubernetes中更新api版本列表 [英] How to update api versions list in Kubernetes

问题描述

我正在尝试在本教程.而且我也在使用Google Kubernetes Engine.

I am trying to use "autoscaling/v2beta2" apiVersion in my configuration following this tutorial. And also I am on Google Kubernetes Engine.

但是我收到此错误:

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

当我列出可用的api版本时:

When I list the available api-versions:

$ kubectl api-versions

admissionregistration.k8s.io/v1beta1
apiextensions.k8s.io/v1beta1
apiregistration.k8s.io/v1
apiregistration.k8s.io/v1beta1
apps/v1
apps/v1beta1
apps/v1beta2
authentication.k8s.io/v1
authentication.k8s.io/v1beta1
authorization.k8s.io/v1
authorization.k8s.io/v1beta1
autoscaling/v1
autoscaling/v2beta1
batch/v1
batch/v1beta1
certificates.k8s.io/v1beta1
certmanager.k8s.io/v1alpha1
cloud.google.com/v1beta1
coordination.k8s.io/v1beta1
custom.metrics.k8s.io/v1beta1
extensions/v1beta1
external.metrics.k8s.io/v1beta1
internal.autoscaling.k8s.io/v1alpha1
metrics.k8s.io/v1beta1
networking.gke.io/v1beta1
networking.k8s.io/v1
policy/v1beta1
rbac.authorization.k8s.io/v1
rbac.authorization.k8s.io/v1beta1
scalingpolicy.kope.io/v1alpha1
scheduling.k8s.io/v1beta1
storage.k8s.io/v1
storage.k8s.io/v1beta1
v1

所以我确实缺少了autoscaling/v2beta2.

So indeed I am missing autoscaling/v2beta2.

然后我检查我的kubernetes版本:

Then I check my kubernetes version:

$ 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"}

所以看起来我的版本为1.13.6.自1.12以来，应该可以使用autoscaling/v2beta2.

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

那为什么对我不可用?

推荐答案

不幸的是，HPA自动缩放API v2beta2在GKE上尚不可用.它可以与Kubeadm和Minikube自由使用.

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