We are deploying a Jenkins instance using Helm on our Kubernetes cluster. Our cluster is inside a firewall and we have a custom Jenkins Update Center that we are supposed to use.

Without manually going to the UI and updating, how do I make sure that the Jenkins instance has this custom Update Center at the time it is deployed. It needs some plugins and so we want to use our update center to download the plugins required at the time of installation.

I am looking for a way to provide the update center details in the helm charts itself so that Jenkins gets deployed with the correct update center.
