title: Need Cloudwatch rule (scheduled one) that runs only once
body: <p>I've understood AWS Cloudwatch <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html" rel="noreferrer">Scheduled Rules</a> (Amazon EventBridge Rules) which works by defining CRON expression.</p>
  <p>The documentation mentions rules that triggers repetitively on a given time. Such as, run a Cloudwatch rule every 15 mins and so on.</p>
  <p>What I want is a Rule that runs only ONCE. Any ways to achieve it? For example, run a rule after 1 hour from now, and thereafter it should never run.</p>
  <p>Any solution?</p>
  <p>PS: I've checked event based rule also but I don't have any event that can trigger rule.</p>
