# Script to replace EC2 instances in an ECS cluster's auto-scaling group after
# changing the AMI or instance type in the launch configuration. It 
# checks for instances with the incorrect AMI or type, scales up the
# auto-scaling group with replacement instances, then drains the tasks
# from the old instances.
#
# Usage: aws-vault exec profile-name -- python3 replace_ecs_cluster_instances.py --group=asg-name --cluster=ecs-cluster-name --count=3
