dedicated agents are not able to connect



  • John Mellor

    Ok, what is a "CJOC_URL"?  Gobbledegook phrase meaning "Canadian Joint Operations Command"?

    If the slave.jar has a different md5, how do I interpret that?  What API versions are compatible, and how do I determine that compatibility?

    I have a JNLP connection issue in K8S, and this document falls far short of what is required to debug this.

    CJOC stands for CloudBees Jenkins Enterprise. For the purposes of this article, it should have just been JENKINS_URL.

    If the hash sum is different it means the versions are different between master and agent. The backward compatibility is maintained but the recommendation is to keep the slave.jar at the same version on both sides. Therefore if md5 is different, replace agent's slave.jar with the one downloaded from the master.

    In the Load balancer or ha-proxy section, there should be a comment about Idle Timeouts if you're Jenkins node is running through a LB/proxy.  This can cause JNLP connection timeout errors

    The default for ELB for instance is 60s and was causing some builds on slave nodes to fail on certain steps that took a long time to respond.

    CLI authentication format has changed, it should be:

    java -jar jenkins-cli.jar -s http://<JENKINS_URL>/  -auth <username>:<APItoken> help
