	// By default, the newest image is used on each deployment. This will cause
	// instances to be replaced whenever a new version is released, and may cause
	// downtime if there aren't enough running instances in the AutoScalingGroup
	// to reschedule the tasks on.
	//
	// If set to true, the AMI ID will be cached in `cdk.context.json` and the
	// same value will be used on future runs. Your instances will not be replaced
	// but your AMI version will grow old over time. To refresh the AMI lookup,
	// you will have to evict the value from the cache using the `cdk context`
	// command. See https://docs.aws.amazon.com/cdk/latest/guide/context.html for
	// more information.
	//
	// Can not be set to `true` in environment-agnostic stacks.
