REQUIRED DATA:

  • VpcId: The VPC you are using, this should be the same as the previously used VPC.

  • AMI-ID: This value determines what kind of EC2 instances your Auto Scaling group (ASG) will spin up. Be sure to select an AMI in your account that starts with "customer-" and is of the operating system that you want. Find AMI IDs with the For the AMS SKMS API reference, see the Reports tab in the AWS Artifact Console. operation (CLI: list-amis) or in the AMS Console VPCs -> VPCs details page. This walkthrough is for ASGs configured to use a Linux AMI.

  • ASGLoadBalancerNames: The load balancer that you previously created--find the name by looking at the EC2 Console -> Load Balancers (in the left nav). Note this is not the "Name" that you specified when you created the ELB previously.
