I'm using the stable helm chart in order to deploy it in my OCP environment.
I activate the persistence volume where jenkins save the jenkins_home folder.
I found that the helm chart define the plugin and plugin-dir folder as empty volume folder.
It's cause to download the plugins every time when pod is restarted.
How can I configure it that plugin dir will be also configured as persistence volume?
I think the problem lies in this line.
The default value for the overwritePlugins variable is true.
This means that if you do not explicitly set it to false, the ConfigMap that will be generated will create the following line, in an inline script to be executed
rm -rf /var/jenkins_home/plugins/*Then, and assuming you have elements in the installPlugins list, it will proceed with (re-downloading) and installing those plugins.
Keep in mind that it seems that AFTER installation, plugins seem to end up to /var/jenkins_home/plugins that (assuming you have set a PVC) is a persistent location.
