Vincent Latombe do you know what's the concurrency model for cloud provisioner?

Re: Agent creation failure because of concurrent attempts to schedule a pod

AFAICT from these logs, there are several threads calling KubernetesLauncher#launch.

However, these are supposed to be initiated by Computer#connect, which includes some control to prevent multiple launches from happening (unless it is triggered using a 'force' attribute).

Re: Agent creation failure because of concurrent attempts to schedule a pod

this is mitigated in 1.13.9 as it won't wait for deleted pods
https://github.com/jenkinsci/kubernetes-plugin/blob/master/CHANGELOG.md#1139

please reopen if still happening in latest version

Re: Agent creation failure because of concurrent attempts to schedule a pod

We observed this in version 1.17.2 of the kubernetes-plugin. We had reached our maximum pod limit (100) in our kubernetes cluster, all of which had failing JNLP containers. They all had the same error: the master had refused the connection as it had an 'unknown client name'

Agent JNLP container logs:

Here is the jenkins master log of a single one of these failing pods (ui-pipeline-shared-7sdt7). Apologies I did not discover[ the debug logging settings|https://github.com/jenkinsci/kubernetes-plugin#debugging] during our incident so I do not have much logs:

Re: Agent creation failure because of concurrent attempts to schedule a pod

During our incident, deleting 1-3 pods would result in more pods coming up with the same error from the JNLP container.

However, when we deleted all 100 of them, the next pods to start did not have this error.

Script used to delete all the failed slaves in our 'cicd' namespace:

 
                                                                for pod in $(kubectl get pods -n cicd -ojson -ljenkins=slave | jq '.items[].metadata.name' -r); do kubectl delete -n cicd pod "$pod" --wait=false; done  
                                                            

I will try to reproduce this issue, but I believe that the high number of running pods is critical here.

Re: Agent creation failure because of concurrent attempts to schedule a pod

Looking through the code base I'm unclear where this could be happening. This is where things are first being terminated:

org.csanchez.jenkins.plugins.kubernetes.KubernetesSlave _terminate

So this must be called incorrectly somewhere. However it can only be called by:

AbstractCloudSlave.terminate() (hudson.slaves)

Which in turn can only be called from one of three places – I hope I'm missing something here:

KubernetesLauncher.launch(SlaveComputer, TaskListener) (org.csanchez.jenkins.plugins.kubernetes)
CloudRetentionStrategy.check(AbstractCloudComputer) (hudson.slaves)
AbstractCloudComputer.doDoDelete() (hudson.slaves)
DeleteNodeCommand.run() (hudson.cli)

#1 can't happen because that requires a log statement {{"Error in provisioning; agent=%s, template=%s" }}to happen before the observed log statement, where instead it appears after (on the second termination).

#2 can't be happening, as i logs a "Disconnecting {0}" with computer.name() – these only appear for "jnlp-" computers

#3 can't be happening as I'm not running any CLI commands at the time

Re: Agent creation failure because of concurrent attempts to schedule a pod

I can reproduce this issue when I disable “Do not allow concurrent builds” and run pipeline job for couple times at the same time

Our agent using kub2iam and I don’t know when and why Jenkins-master had refused the connection as it had an 'unknown client name’… maybe this is due to kub2iam, which we use for our agent… maybe something else...

1. Enable option “Do not allow concurrent builds” - this should help prevent this issue.

2. Deleting Error pods - should help prevent reaching the maximum pod limit in the kubernetes cluster

3. Stop current job - should prevent to generate Error pods…

I hope this helps
