API to update AutoScaling group (values for min, max, and desired count as values for the mentioned autoscaling group.)

Step1:- First we are creating an s3 bucket and an object (Lambda function code ) in it. For that, we have an s3 directory for Terraform code first we will deploy that.

.. /S3 $terraform apply

Step 3:- Now we are creating policies and roles for the communication between AWS resources also creating Lambda function and API Gateway. Terraform script for the same is inside Terraform directory.

../Terraform $terraform apply

Step 4:- This will give an invoke_url (Post API URL)

complete_invoke_url = "https://5tbkkuk676.execute-api.us-east-1.amazonaws.com/dev/resource"

Step 5:- In this, we will pass our parameters (ASG-Name,CesiredCapacity,MinimumCapacity,MaximumCapacity)

https://5tbkkuk676.execute-api.us-east-1.amazonaws.com/dev/resource?

Curl Request

curl --location --request POST 'https://izoaehgcz1.execute-api.us-east-1.amazonaws.com/dev/resource?ASG-Name=testScaling&DesiredCapacity=0&MinimumCapacity=0&MaximumCapacity=0'
