[Sebastian Łaskawiec (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-6489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13268490#comment-13268490 ] 

Sebastian Łaskawiec commented on ISPN-6489:
-------------------------------------------

[Kubernetes built-in Autoscaler|http://kubernetes.io/docs/user-guide/horizontal-pod-autoscaling] supports setting min/max number of instances. Setting properly the minimum value is the key for having a healthy cluster. 

A suggested way to do it is to let Infinispan calculate the minimum topology and invoke Kubernetes API from inside of the Pod (Kubernetes mounts TOKEN for invoking the API in {{/var/run/secrets}}).

> During the conference [Ray|https://twitter.com/saturnism] mentioned that it would be really nice to have Openshift autoscaling policies for Infinispan based on:
> * number of entries (and/or)
> * memory usage
> Some examples might be found in his repos
