Subject ClusterGroup fallback
Date Fri, 14 Apr 2017 12:44:25 GMT
Hi Igniters!

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.
