# Script to replace EC2 instances in an ECS cluster's auto-scaling group after

# 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
