|cloud node provisioning while having idle Mode.EXCLUSIVE nodes||Ivan Meredith||5/23/12 12:57 AM|
I have a couple of executors connected to DEV@cloud Jenkins, however
they are reserved for jobs that specify their specific labels, all
other jobs (including ones that dont specify labels) need to run on
The issue I'm running into is that when it comes to build a job (that
specifies no label), Jenkins does not start the cloud node. Jenkins
sees that there are 2 idle executors, and so doesn't provision any
cloud nodes, even though the job wont run because they are marked as
I suspect the way we use the cloud extension point in DEV@cloud
exacerbates this issue as we disconnect the slave as soon as the job
queue is empty. I'm not sure if other cloud plugins do this?
When I specify a label that the cloud can provision, it all works fine.
I think the issue is that NodeProvisioner use OverallLoadStatistics
doesn't take into account of the above use case.Probably a patch for
NodeProvisioner is needed - at first I thought it was
OverallLoadStatistics that was wrong, but now I dont think so after
finding that labels implement their own stats.
Any ideas on what the 'right way' is to fix this bug?

Well, it looks like I was able to hack something working with

not a good solution, and not something that could go back into
