> Key: STRATOS-677
> URL: https://issues.apache.org/jira/browse/STRATOS-677
> Project: Stratos
> Issue Type: Bug
> Components: Autoscaler, Cloud Controller, Eventing
> Affects Versions: 4.0.0
> Reporter: Reka Thirunavukkarasu
> Assignee: Reka Thirunavukkarasu
> Fix For: 4.0.1
>
>
> Even after unsubscribing from a cartridge also, instances are getting
> spawned. The reason for this is, while the CC terminates instances, if the
> minimum rule executed in AS side, then AS will request to spin a new
> instances as it is below the minimum count.
> In order to make AS aware of the unsubscription, we need to introduce another
> state to cluster saying CLUSTER_IN_MAINTENANCE. So that once all the
> instances are terminated, cluster can be removed as well as AS can pause the
> cluster monitor when it is in maintenance mode. Even this state can be useful
> when applying patches or upgrading the cluster.
