Similar to https://issues.jenkins-ci.org/browse/JENKINS-53876
Unfortunately with the latest 1.40.1 EC2 nodes are not launching anymore:

Reverting back to 1.39 solves the issue.
I see m5d instances being mentioned in the changelog - which we are using - perhaps related?

[ [https://github.com/jenkinsci/ec2-plugin/pull/252 :|https://github.com/jenkinsci/ec2-plugin/pull/252] It implements very simple algorithm: * if NodeProvisioner requested X executors, start to raise X/N nodes (N is number of executors on each node). * if there is any orphant nodes (~not known by Jenkins at all), take them in account (and start if it's neccessary) * if there is not enough orphant nodes - raise needed nodes in parallel * give them back to NodeProvisioner in RUNNING state ] |
