No agents created when using google compute engine and missing instance template entry

XMLWordPrintable

      Ran into an issue where after updating the Google Compute Engine Plugin  1.0.8 cloud environment module for the latest security updates, not having an Instance Template in google cloud causes jobs to queue up with no agents being built. The logs show

      If it's required that the Instance Template is required, then the field should be marked as required in the configuration screen, but currently does not require it. Once we created an instance template and assigned it under 'Machine Configuration'->'Template to use', the agents started being built correctly.

          Hi, we have just run into this issue.

          We have updated the plugin time ago, and today I was on the general Jenkins configuration page (Jenkins -> Manage Jenkins -> Configure System), where I have clicked the save button.

          Instantly, my Jenkins was not able to create nodes anymore because of that error.

          I think that the save caused the tag <template></template> to be added to the configuration file, and from now on the empty string is sent every time when creating a node, and GCP API complains because it's invalid.

          In my opinion this a Critical/Blocker issue as it completely breaks the functionality.

          Deleting

          {{<template></template> }}

          from

          config.xml

          Fixed the scheduling issue I was having.

          We've since patched the bug with our new release. The problem is that not using template led to this exception. If you use the new release, it should stop. See this PR: https://github.com/jenkinsci/google-compute-engine-plugin/pull/21

           

          Closing now.
