Scale multiple ECS services at once

You use the following bash script I wrote to scale multiple ECS services at once:

	#!/bin/bash
	# service_text_file is the path to a text file that contains a list of service names, each service name is on each line
	cluster=$1
	service_text_file=$2
	desired_count=$3
	while IFS= read -r line
	do
	echo "$line"
	aws ecs update-service --cluster "$cluster" --service "$line" --desired-count 0 >/dev/null 2>&1
	done < "$service_text_file"

Prerequisite

- AWS CLI [1]
- An IAM account that has permission to update or scale ECS services
- A text file that contains all the ECS service names, each line contains 1 service name. For example:

service1
service2
...

Usage

./mass_scale_ecs_svc.sh <cluster name> <path to the ECS service names text file> <desired count, e.g., 0>
