Wolkenobergrenze Automatischer Kostendeckel für Amazons Cloud-Server c't 12/2018, S. 168 ----------------------------------------------------------- ec2stoptagged.py Kostendeckel (Python-2.7-Funktion für Amazon Lambda) lambda-role Role der Lambda-Funktion topic-policy Topic-Policy für Alarm-SNS ----------------------------------------------------------- Update Christian Schwabe 31.5.2018 The original Script use AWS Budgets to trigger events to stop tagged instances in all AWS regions. Update of this Version to have a PoC for just the function with trigger through SNS. No trigger with budget control! Only for instances in Ireland region! You need: - Tagged and unTagged EC2 Instances - Lambda function (python script) - Lambda role - Lambda TestEvent (just to test the lambda function) - SNS Topic (Topic Name = Tag for the Instance) How it works: - Build and tag your instances - Create Lambda function (python 2.7), create CustomRole, copy py script - To test the Lambda function, test with TestEvent (comment return for every trigger in py script - row 22) - Create topic for SNS with the name of the tagged instance to stop - Create subscription for this topic, use AWS Lambda as protocol and the ARN from your Lambda function - TEST!!!! - Publish a message via SNS dashboard, use the ARN from your topic, as subject use "AutoShutDownTrigger", no matter what message ! If you change the subject of the message -> nothing will be stoped ! If your SNS topic name is not equal to the instance tag -> nothing will be stoped ! So it is possible to have one SNS topic for each tag you like to trigger
