Some jobs are being migrated to Nodepool. Right now it has a base pool of 10 instances and can raise it up to 20 depending on jobs in Zuul Gearman queue.

The idea we talked about in our 1:1:

  • Spawn a lot of dummy commits for repos that are tested on nodepool, enough to cause it to spin up more instances
  • watch it do that
  • take a screenshot of the resulting pretty graph
  • profit (aka: call this task done with supporting evidence)

I sent 12 patches against integration/config each triggering two jobs running on nodepool for a total of 24 jobs.

Experiment done around 2015-12-02 22:00 UTC. Will parse the Nodepool logs to verify its behavior.

Per confirmation with @hashar, this is done.
