2.3.1. Deploying your Node.js app: --generator is deprecated

[rbondi]

The chapter section says to run this command:

$ kubectl run kubia --image=luksa/kubia --port=8080 --generator=run/v1

With v1.18.1 of minikube, this returns:

Flag --generator has been deprecated, has no effect and will be removed in the future.

@rbondi from what I know, the command you mentioned is to create a replication controller is present in the 1st edition of the book which was released quite long back. Kubernetes has been updated quite a lot from then.

In earlier versions of kubernetes, a kubectl run command would create a deployment and in order to create an rc one would require to pass --generator=run/v1 flag.

In latest version (22, as of writing this comment) kubectl run would only create a pod and not a deployment and --generator flag has been deprecated.

@sxddhxrthx would you mind giving advice on which book should I read nowadays to learn Kubernetes?
