shutdown and startup AWS CloudFormation EC2 and RDS instances

AWS CloudFormation power switch

AWS CloudFormation power switch allows you to shutdown and startup all EC2, RDS and AutoScaling instances managed by one or more CloudFormation stacks.

install the power switch

to install the power switch, type:

pip install aws-cloudformation-power-switch

shutdown

to shutdown all instances managed by CloudFormation stacks starting with the name dev, type:

cfn-power-switch --dry-run --stack-name-prefix dev on

This will show you which EC2, RDS and AutoScaling instances will be shutdown. For Auto Scaling groups, the desired number of instances is set to 0. If the minimum is greater than 0, it will change the minimum setting too.

startup`

to startup all instances managed by a CloudFormation stacks starting with the name dev, type:

cfn-power-switch --dry-run --stack-name-prefix dev off

This will show you which EC2, RDS and AutoScaling instances will be started. The AutoScaling desired number of instances will be set the maximum desired instances. Remove the --dry-run and it will be activated.

deploy the power switch

To deploy the power switch as an AWS Lambda, type:

git clone https://github.com/binxio/aws-cloudformation-power-switch.git
cd aws-cloudformation-power-switch.git
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 *)"

This will shutdown down all EC2, RDS and Auto Scaling instances managed by CloudFormation stacks starting with the name dev at 23:30 and start them backup at 7:30 in the morning.

caveats

the RDS clusters are not detected as CloudFormation does not place aws:cloudformation: tags on the resource.
