Helllo,

Hi Ramesher,

Best to use the Q&A in Udemy if you want a fast response. To fix this error you'll need to create mykey using "ssh-keygen -f mykey"

You shouldn't use the remote provisioner for this. Amazon has user-data that you can use which is executed when the instance starts, and when the volume is attached. You can use the script in jenkins-packer-demo/scripts/ which attaches a volume for jenkins. It waits until the volume is attached, checks whether there is a filesystem, and formats it if there isn't. Should work for your use-case as well.
