We've written a groovy script (sample attached) that we're hoping to use to add slave templates to our EC2 cloud. At the moment, we're only executing via the script console but we have plans to eventually automate the process and run it as part of a build.Â
The script executes successfully and when we check under the EC2 cloud settings, we can see our new template there.Â
However, when we try to run a build with a label matching that of the new slave template, we see the following node provisioning error in the logs:
hudson.plugins.ec2.EC2Cloud provision
INFO: SlaveTemplate{ami='', labels='oracle-dbupgrade-f30e32f
'}. Attempting to provision slave needed by excess workload of 1 units

If we then go back into the 'Manage Jenkins' settings and click apply without making any changes, things burst into life and the new slaves begin to launch.Â
