Thanks Chamila, Got great answers with the Kubernetes auto scaling (via node v 1.1 and or node). But would like to know what's the Stratos auto scaling functions with Kubernetes?
etc: in Stratos we setup the auto scaling policy for the kubernetes cluster, when and how can this auto scaling policy work? ( will scaling the new pod or node ? ) Thanks -D On Tue, Jan 26, 2016 at 11:16 AM, Chamila De Alwis <chami...@wso2.com> wrote: > Hi David, > > On Tue, Jan 26, 2016 at 8:28 PM, David Hbase <davidhb...@gmail.com> wrote: > >> >> 1.
