AWS boto3 image waiter is not working properly

Question

I am trying to write a python script with boto3 to create an AMI of an instance and tag the AMI and snapshots. Once the AMI creation function executes I want the script to wait/sleep until the resources are created. To do that I tried the below function. But it doesn't work, Any help here?

  ec2res = boto3.resource('ec2')
  ec2res.Image('ami-XXXXXX').wait_until_exists()

Answer 1

The image exists. Otherwise you wouldn't have an image ID to plug into your code. That's why the waiter is returning immediately. What you likely want is Image Available
