title: Kubenetes: Is it possible to hit multiple pods with a single request in Kubernetes cluster
body: <p>I want to clear cache in all the pods in my Kubernetes namespace. I want to send one request to the end-point which will then send a HTTP call to all the pods in the namespace to clear cache. Currently, I can hit only one pod using Kubernetes and I do not have control over which pod would get hit.</p>
  
  <p>Even though the load-balancer is set to RR, continuously hitting the pods(n number of times, where n is the total number of pods) doesn't help as some other requests can creep in.</p>
  
  <p>The same issue was discussed here, but I couldn't find a solution for the implementation:
  <a href="https://github.com/kubernetes/kubernetes/issues/18755" rel="noreferrer">https://github.com/kubernetes/kubernetes/issues/18755</a></p>
  
  <p>I'm trying to implement the clearing cache part using Hazelcast, wherein I will store all the cache and Hazelcast automatically takes care of the cache update.</p>
  
  <p>If there is an alternative approach for this problem, or a way to configure kubernetes to hit all end-points for some specific requests, sharing here would be a great help.</p>
