Onboard Workload(s) from AWS Auto Scaling Group

To onboard a workload deployed on AWS Auto Scaling Group (ASG), you will need to perform all setup actions as part of the instance launch script instead of executing commands on the EC2 instance.

In a nutshell, you will need to move setup commands from previous steps into the cloud-init configuration associated with instances in the Auto Scaling Group.


  1. Move setup commands from the Install Bookinfo Ratings application step
  2. Move setup commands from the Install Istio sidecar step
  3. Move setup commands from the Install Workload Onboarding Agent on AWS EC2 instance step
  4. Move setup commands from the Onboard workload from AWS EC2 instance step

The following configuration is a sample that has all of the steps joined together. Replace example-ca-certificate with the with the value of example-ca.crt.pem, and ONBOARDING_ENDPOINT_ADDRESS with the value that you have obtained earlier.

Once the data is associated with the user data of your Auto Scaling Group, try scaling up and down the Auto Scaling Group, and verify that the Workload is onboarded properly
