I am trying to create an AMI from an instance store instance on amazon

  • 0

I am trying to create an AMI from an “instance store” instance on amazon EC2. This is what I did

  1. Took an existing fedora ami from community- ami-72bf441b
  2. Launched the system and made some modifications
  3. Now I am trying to create an ami for the newly launched system using http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/creating-snapshot-s3-linux.html
  4. Reached the point where I need to copy cert key
    “Copy your Amazon EC2 private key and X.509 certificate to the directory where an instance store is mounted using a secure copy function such as SCP.”

Here I am stuck as to how can find the directory where instance store is mounted? The documentation says /media/ephemeral0 or /dev/sdf, but no such directories are present

    Basically on an instance store AMI almost all directories are ephemeral. Perhaps they mean, you should not copy to an manually attached EBS or network filesystems. Not sure. Anyways, I find this howto easier to follow.

    Whatever howto you use make sure the resulting AMI does NOT contain your certificate and key for obvious security reasons. You may need to use the -e flag.
