This site is a starting point for every aspect of Operator Service management, customization and configuration on Azure.
In order to get existing Jenkins configuration, run the following command:
$ kubectl -n jenkins get jenkins -o yaml > jenkins_cr.yaml
This command will save current Jenkins Custom Resource into jenkins_cr.yaml file. Every time you want to change the configuration, you have to get the current version first and update it.
$ kubectl -n jenkins apply -f jenkins_cr.yaml
For information on how to configure your Jenkins instance from code please refer to Customizing Jenkins instance guide.
