Auto-scaling with a custom, private AMI

Question

I'm trying to set up an auto scaling profile to scale my own cloud automatically. I have created a private AMI image which I'd like to use as the image launched when creating new servers in this configuration. I'm using the auto-scaling command-line controls to create the profile and I can't seem to get it working:

$ as-create-launch-config MyServerConfig --image-id "ami-12345678" --instance-type m2.4xlarge --monitoring-disabled
as-create-launch-config: Malformed input-AMI ami-12345678 is invalid: The AMI ID 'ami-12345678' does not exist

I've verified that the AMI id that I'm using does, in fact, exist in my EC2/Images/AMIs part of the EC2 console. What am I doing wrong here? I need to have the images be private due to the company's privacy requirements, but I do need to set up auto-scaling to get things going for them.

Answer 1

Make sure your AMI and the AutoScaling group are in the same region and that you are correctly specifying that region in the command line.
