I want to discuss if it possible to implement ClusterGroup fallback, i.e. create a chained cluster group ClusterGroup1->ClusterGroup2 that will refer to nodes satisfying conditions for ClusterGroup1 while there are such nodes and if no such nodes become available then the nodes satisfying ClusterGroup2 conditions will come into play. As an example, consider a case when service per node should be deployed on server nodes located on a specific host. If all the server nodes on the host go down, then all the remaining server nodes should be used for service deployment. Any thoughts? Kind regards, Alex. --001a114dd26a3416a2054d1fcd56--
