Jenkins CaSC - Kubernetes

Using Jenkins
1

Hi,
I am using Jenkins deployed in Kubernetes.
I also used CasC which I define in values.yaml section of the helm chart, by adding it to the configScripts section.
It works but its not optimal. I would like to have CaSc defined outside of values.yaml and inject it, I tried:

  1. Placing casc.yaml config files in the folder of "/var/jenkins_home/casc_config/jenkins.yaml but I wasnt able to get it to work
  2. Similarly adding git repo with yamls in ConfigUrls didnt work.
    I guess issue could be due to lack of permissions or wrong setup, would anyone who got it to work be able to share with me how they configured it?
JCasC:
    # -- Enables default Jenkins configuration via configuration as code plugin
    defaultConfig: true

    # If true, the init container deletes all the plugin config files and Jenkins Config as Code overwrites any existing configuration
    # -- Whether Jenkins Config as Code should overwrite any existing configuration
    overwriteConfiguration: false
    # -- Remote URLs for configuration files.
    configUrls: []
    # - https://acme.org/jenkins.yaml
    # -- List of Jenkins Config as Code scripts
    configScripts: 
      welcome-message: |
        jenkins:
          systemMessage: Welcome to our CI\CD server. This Jenkins is configured and managed 'as code'.

I was never able to get it working by any other method other than in the values yaml section of the helm chart.
