我尝试在this tutorial之后的配置中使用“autoscaling / v2beta2” apiVersion。而且我也在使用Google Kubernetes Engine。
但是我得到这个错误: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:
$ 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

cloud.google.com/v1beta1

external.metrics.k8s.io/v1beta1
internal.autoscaling.k8s.io/v1alpha1

networking.gke.io/v1beta1
networking.k8s.io/v1

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
所以确实我缺少了autoscaling / v2beta2。
然后我检查我的kubernetes版本:
$ 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"}
所以看起来我有一个1.13.6的版本。自1.12版以来，自动缩放/ v2beta2可用。
那为什么对我不可用？
最佳答案
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。
