amazon web services - Create AMI when EC2 instance shuts down -


i need create ami when instance terminated/shuts down up. setup cloudwatch rule on ec2 instance state changed event create ami via ssm run command (target document aws-runshellscript(linux)). works fine, if provide hardcoded instance id command parameter.

/home/ec2-user/createimage.sh i-123456

this rule needs applied instances. need instance-id dynamically source , send target. tried input transformer not getting data source. dynamic parameters {{variable name}} not working. suggestions.

thanks.

you can configure amazon cloudwatch events rule:

amazon cloudwatch events rule

you can have rule trigger aws lambda function triggers snapshot. when lambda function triggered, following information passed function:

{   "version": "0",   "id": "01345791-08ce-baaf-78f5-437aca50f13c",   "detail-type": "ec2 instance state-change notification",   "source": "aws.ec2",   "account": "123456789012",   "time": "2017-09-12t00:28:55z",   "region": "ap-southeast-2",   "resources": [     "arn:aws:ec2:ap-southeast-2:123456789012:instance/i-0cf605453b22f703e"   ],   "detail": {     "instance-id": "i-0cf605453b22f703e",     "state": "stopped"   } }

note instance id passed message, can use in createsnapshot command within lambda function.
