-----------------------------------
Hi [~asuresh]
Could you please elaborate what do you mean by "to allow ALL attributes to be
scope-able or just a pre-configured subset"? I took a look at this today, I
think in terms of node-attributes, the only scope makes sense is "*NODE*". E.g
{target: node-attribute:*host* IN "n1,n2,n3", *scope*: "host"}
that constrains the allocations to nodes where attribute {{host}} is "n1", "n2"
or "n3". You can't specify an attribute in scope right? Just want to get to the
same page.
Thanks

> Issue Type: Sub-task
> Reporter: Arun Suresh
> Assignee: Weiwei Yang
> Priority: Major

> Currently, we have only two scopes defined: NODE and RACK against which we
> check the cardinality of the placement.
> This idea should be extended to support node-attribute scopes. For eg:
> Placement of containers across *upgrade domains* and *failure domains*.
