title: In AWS Codepipeline how do you skip a database cluster deploy step
body: <p>I have an AWS Aurora database cluster that will need to be deployed to multiple environments. I'd like to make this easier on our Ops team by just including this cluster deploy in the the code pipeline but I need to add a conditional to prevent the database cluster from being deployed on successive builds and I'm not sure how to do this. I believe I should use a precondition on this build step but how do I check if the cluster has already been deployed?</p>
