cd aws-cloudwatch-log-minder
aws cloudformation deploy \
	--capabilities CAPABILITY_IAM \
	--stack-name aws-cloudformation-power-switch \
	--template-file ./cloudformation/aws-cloudformation-power-switch.yaml \
    --override-parameters \
        StackNamePrefix=dev \
	    "Startup=cron(30 7 ? * MON-FRI *)" \
        "Shutdown=cron(30 23 ? * MON-FRI *)"
