title: Kubernetes: Limit number of simultaneous deployments
body: <p>Is there a way to limit the number of deployments a Kubernetes cluster will implement at once? With rolling deployments and 100% uptime, it's possible that updating all deployments at once could overload the nodes.</p>
  
  <p>I know it is possible to limit the number of pods deployed per-namespace, but i was wondering if it is also possible to limit simultaneous deployments in a similar way. Say, for example, maximum of 10 deployments at once.</p>
  
  <p>I could probably script out a limit to the number of deployments I send to the k8s API at once, but it would be nice if there was a setting I could use instead.</p>
