I see m5d instances being mentioned in the changelog - which we are using - perhaps related?      Add Comment

Re: Linux slaves are not starting anymore I've found this hit or miss, sometimes it happens sometimes it doesn't.   Mostly it happens when we've changed pre-existing connections and it only happens for spot instances. Switching our instances to on demand does not have the same problem.

Re: Linux slaves are not starting anymore

Do you know if the spot instance after the restart is still alive ?  Are you in VPC or in Default ?  Are you using public IP ?

Re: Linux slaves are not starting anymore

We just started hitting this. We've been running 1.40.1 for a couple of days (and the latest Jenkins version) without seeing it but then I added a new agent template, and trying to manually launch an agent from the template caused this error to occur. I haven't seen it in any of the instances that were started by the node provisioner, but I do see it when I manually launch an agent using one of the templates that has been working fine for the last few days. It doesn't happen every time though. We use spot instances, in a VPC, with no public IP. The instance is left running afterwards. I haven't seen it happen with on-demand instances.

Re: Linux slaves are not starting anymore

We consistently hit this error using spot instances with the latest LTS Jenkins version. Using spot instances in a VPC with no public IP.

Re: Linux slaves are not starting anymore

Seeing identical issue using M5.Xlarge, latest Jenkins, and Spot Instances. If I hit "Launch Agent" before the timeout is hit, but after it's completed booting it is successfully able to add it.

Re: Linux slaves are not starting anymore

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

Re: Linux slaves are not starting anymore Any updates on this? This failure to start spot instances makes it infeasible for us to upgrade past 1.39, but the occasional deadlocks when spawning instances (fixed in 1.42, apparently https://issues.jenkins-ci.org/browse/JENKINS-54187) are extremely disruptive.

Re: Linux slaves are not starting anymore

Installed 1.45 on my Jenkins. Upgraded from 1.43. Hopefully it'll solve the issue of slaves stuck in offline mode. Till today's morning, the issue was that the instances were up and running and the slaves were offline. Today's morning the instances were down as well as the slaves.

OK. Seems like it got worse. Usually it happened during the weekend or after a night. Now slaves fails to start during the day I'm out of ideas

Re: Linux slaves are not starting anymore

Yesterday morning I came and it looked fine. This morning, again, all instances were up and all slaves were offline while there were a few jobs in the queue waiting for a long time. It's not just not starting the slaves, it's even worse, the instances are running and wasting money which is the opposite of what this plugin is all about.

I have changed the configuration to use terminate/start instead of stop/start and for a week it works just fine. Maybe it might help solving this issue

the interesting part is this: it fails for spot inst images c5.2xlarge (or any higher) , if I use t2.2xlarge it works well.

here's the error we are seeing {code:java} ERROR: Unexpected error in launching an agent. This is probably a bug in Jenkins java.lang.NullPointerException at hudson.plugins.ec2.EC2HostAddressProvider.getPrivateIpAddress(EC2HostAddressProvider.java:49) at hudson.plugins.ec2.EC2HostAddressProvider.windows(EC2HostAddressProvider.java:28) at hudson.plugins.ec2.win.EC2WindowsLauncher.connectToWinRM(EC2WindowsLauncher.java:134) at hudson.plugins.ec2.win.EC2WindowsLauncher.launchScript(EC2WindowsLauncher.java:39) at hudson.plugins.ec2.EC2ComputerLauncher.launch(EC2ComputerLauncher.java:48) at hudson.slaves.SlaveComputer.lambda$_connect$0(SlaveComputer.java:291) at jenkins.util.ContextResettingExecutorService$2.call(ContextResettingExecutorService.java:46) at jenkins.security.ImpersonatingExecutorService$2.call(ImpersonatingExecutorService.java:71) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) {code}

Re: Linux slaves are not starting anymore

Jenkins ver. 2.204.2 EC2 plugin: 1.48 we see a similar problem, it crashes on _getPrivateIpAddress_, or _getPublicIpAddress_ call depending on what I have chosen as connection strategy (public IP or private IP).

the interesting part is this: it fails for spot inst images c5.2xlarge (or any higher , I made sure we bid enough to get those instances ), if I use t2.2xlarge it works well.

Later edit:  we updated the EC2 plugin to version [1.49.1|http://52.206.240.15:8080/pluginManager/plugin/ec2/thirdPartyLicenses] and it doesn't repro anymore.
