mbonig.nightynight 1.66.0.post2

A CDK construct that will automatically stop a running EC2 instance at a given time.

NightyNight!

Do you have a EC2 instance that you only need during certain hours of the day? Do you want to reduce it's cost? How about just stopping it every night?

That's the NightyNight construct. It's very simple. Give it an instanceId and it will create a Lambda and a CloudWatch Event Rule to fire the lambda at a specific time of day. If the instance is running, it's stopped.

This is a pre-release!

This is a quick first-draft. All the options that will likely need to be added to accomodate a large number of use-cases are still needed. If you'd like to make requests or help update this construct, please open an Issue or a PR.

What is creates

• A Rule that will, on a given schedule, fire a lambda.
• A Lambda with permissions to describe ec2 instances. It will read the instance by the given instanceId and then stop the instance if it's in a running state.

Example:

# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
class NightynightStack(Stack):

    def __init__(self, scope, id, props):
        super().__init__(scope, id, props)

        # The code that defines your stack goes here
        NightyNight(self, "nighty-night", instance_id="i-123123123123")

This will stop the instance with id i-123123123123 at (the default) 4am GMT.
