[HTCondor-users] Job Transform question

[Thomas Birkett - STFC UKRI <thomas.birkett@xxxxxxxxxx>]

Hi all,

 

I have a potentially simple question but one I’m getting rather stuck on. We have the following config in one of our Job Transforms:

 

JOB_TRANSFORM_DefaultDocker @=end

   REQUIREMENTS JobUniverse==5 && DockerImage =?= undefined

   SET WantDocker = true

   EVALSET DockerImage = ifThenElse(NordugridQueue =?= "EL7", "[name of docker image]", "")

@end

 

This transform maps the DockerImage ClassAd to the name of the Docker image given the ClassAd NordugridQueue, this logic has workedfor when we have a single queue or two queues. However I wish to expand this logic in the future as we will likely have more than 2 NordugridQueue’s. Is there a way to define more than 2 IfThenElse mapping statements or is there a more sensible logic to use in this example, almost like a mapping list? We wish to map different Docker images to different queues coming from our NorduGrid CE’s.

 

Many thanks,
