1. What kops version are you running? The command kops version, will display this information.

Version 1.14.0 (git-d5078612f)

2. What Kubernetes version are you running? kubectl version will print the version if a cluster is running or provide the Kubernetes version specified as a kops flag.

Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.3", GitCommit:"2d3c76f9091b6bec110a5e63777c332469e0cba2", GitTreeState:"clean", BuildDate:"2019-08-19T11:13:54Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"darwin/amd64"}

3. What cloud provider are you using?

AWS

4. What commands did you run? What is the simplest way to reproduce this issue?

./kops-api-example -registry s3://liuxun-cluster.k8s.local-state.ym -name kops.api.example.k8s.local -zones ap-southeast-2a,ap-southeast-2b

5. What happened after the commands executed?

error from apply: error building tasks: InstanceGroup not found (for etcd ap-southeast-2a/main): "ap-southeast-2a"

6. What did you expect to happen?

kops create cluster

7. Please provide your cluster manifest. Execute kops get --name my.example.com -o yaml to display your cluster manifest. You may want to remove your cluster name and other sensitive information.

error reading cluster configuration "kops.api.example.k8s.local": error parsing s3://liuxun-cluster.k8s.local-state.ym/kops.api.example.k8s.local/config: no kind "Cluster" is registered for version "kops.k8s.io/v1alpha2" in scheme "k8s.io/kops/pkg/kopscodecs/codecs.go:33"

8. Please run the commands with most verbose logging by adding the -v 10 flag. Paste the logs into this report, or in a gist and provide the gist link here.

9. Anything else do we need to know?

Before execute the ./kops-api-example command, what preparations do you need to do on aws?

After debugging the code, I found this problem, probably because the example did not use the latest code and processing flow of kops.
