jenkins-operator's Issues

make deepcopy-get doesn't work

unfortunately make deepcopy-gen doesn't work for some reason:

as an alternative we can run:

Feature Request: Support installing additional plugins

I see that you can override basePlugins in the CR yaml by specifying spec.master.plugins with something like this:

apiVersion: virtuslab.com/v1alpha1
kind: Jenkins
metadata:
  name: example
spec:
  master:
   image: jenkins/jenkins:lts
   plugins:
     configuration-as-code:1.4:
     - configuration-as-code-support:1.4
...

However, this either uses the default plugins OR the ones specified:

jenkins-operator/pkg/controller/jenkins/jenkins_controller.go

Lines 221 to 224 in a275ed6

	if len(jenkins.Spec.Master.Plugins) == 0 {
	logger.Info("Setting default base plugins")
	changed = true
	jenkins.Spec.Master.Plugins = plugins.BasePlugins()

As far as I understand, we have two options if we want to install additional plugins or update plugins:

1. Override spec.master.plugins with a complete list of plugins and dependencies. This makes it difficult to maintain if jenkins-operator has a new release that uses a new set of base plugins.
2. Write custom .groovy scripts that install the needed plugins. I believe this is the current recommendation in the README.

Let me know if there is another option I'm missing.

My feature request is to add a new option spec.master.additionalPlugins that would just be merged into the default set of plugins. This would make managing plugins a little bit simpler compared to either option I listed, since only the updated or new plugins would need to be specified.
