Node Manager Stack

The Node Manager Stack deploys a Lambda function (using AWS Python SDK boto3) that is hooked up with Auto Scaling Group's life cycle event and manages each cluster node. The following resources will be created by the stack:

• Lambda Function

• IAM Role

• SNS Topic

• Lambda Permission (to invoke)

The Node Manager Stack defines a new IAM role with the following policies:

• ec2:DescribeNetworkInterfaces

• ec2:AttachNetworkInterface

• ec2:DescribeInstances

• autoscaling:CompleteLifecycleAction

• sns:Publish

• logs:CreateLogGroup

• logs:CreateLogStream

• logs:PutLogEvents
