apiVersion: extensions/v1beta1 errors

[thescott]

Hello there
I am writing to reference
demo/hello-k8s/k8s/deployment.yaml
The apiVersion is extensions/v1beta1 which when I try kubectl apply -f with this yaml file I get an error
error: unable to recognize "k8s/deployment.yaml": no matches for kind "Deployment" in version "extensions/v1beta1"
I am using minikube on a MacMini

kubectl version
Client Version: version.Info{Major:"1", Minor:"14", GitVersion:"v1.14.7", GitCommit:"8fca2ec50a6133511b771a11559e24191b1aa2b4", GitTreeState:"clean", BuildDate:"2019-09-18T14:47:22Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.0", GitCommit:"2bd9643cee5b3b3a5ecbd3af49d09018f0773c77", GitTreeState:"clean", BuildDate:"2019-09-18T14:27:17Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}

I was able to resolve by changing the the apiVersion to
apiVersion: apps/v1
I can perform a pull request if you find that to be helpful, thank you I am enjoying the book :D

Hey @thescott, thanks a lot! Very helpful bug report. This is to be expected since Deployments were deprecated out of extensions/v1beta1 in the recent Kubernetes update.

We debated whether to make all our examples use apps/v1, but at the time, there were many Kubernetes installations which were too old to support this. Time moves on, so in the next edition of the book, should there be one, we'll target apps/v1! Meanwhile, we'll make the change in the online examples.
