I fixed this issue, but it become a new issue as below:

Your public key file may be broken or does not exist. Make sure your public key file exists and is valid in /home/ec2-user/.ssh/id_rsa.pub

[liuevan48]

It seems if we generate the public key from somewhere else and import to /home/ec2-user/.ssh/, it won't work. But if we generate the public key in EC2 directly by using "ssh-keygen", the key can be used.

[pahud]

yes, you need to generate your ssh keypair by

1. ssh-keygen
   or
2. generate from your EC2 keypair console, downloading the .pem private key and use ssh-keygen -f to generate its public key

see this demo

updated the README doc to help understand how to generate a public key for kops
