Ok, so I can do this pretty straightforward using SovLabs Custom Naming.
1.) Create new custom properties for the cluster names and a drop-down list for the applications. For applications, I'm just doing a three-character code but this could be anything.
I created "Stefani.ClusterName" on my one and only (since this is a home lab) compute cluster. And I'm using an existing property I already had to specify the application name.
The name we are going for based on what you want is (AppCode)(##)-(ClusterName).
2.) Add naming sequence
I created a new sequence label that will factor into a new naming standard based on this schema. I'm using decimal, opting to reuse those sequence numbers, max length of 2 characters since you only want max of 10, start with 1, pad left digits with zeros if needed, and for the Unique Key I'm saying to let those numbers be unique if the Application code and Cluster Names are unique.
3.) Create a new Naming Standard
Calling this "StefaniOracle" and using the new sequence I just created. The template is {{SovLabs.Naming.Application}}{{sequence.stefaniSequence}}-{{Stefani.ClusterName}}. So essentially if a user picks the app code to be ORA and they're deploying to the R610 cluster, the template says the name has to be ORA##-R610.
Once submitted, a new property group is automatically created based on this standard and sequence.
3.) Attach said property group to my blueprint and fire off a request after selecting an application in the drop-down and asking for two cluster nodes.
4.) See the results
