demo-2 issue

[ramesher]

Helllo,

I am going through your udemy course and and geeting below error for demo-2. Can you please suggest.

I am installing amazon linux.

aws_key_pair.mykey: Creating... aws_key_pair.mykey: Creation complete after 1s [id=mykey] aws_instance.example: Creating... aws_instance.example: Still creating... [10s elapsed] aws_instance.example: Still creating... [20s elapsed] aws_instance.example: Still creating... [30s elapsed]

Error: Error in function call: Call to function "file" failed: no file exists at mykey.

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.
