Jenkins persistent template overriding PV content with image content and boot

[goldmann]

The Jenkins persistent template sets environment variables that are responsible for overriding the content of the PV with default content stored in the image. This results in lost jobs and configuration when the Jenkins instance is redeployed in OpenShift which is not exactly what "persistent" means 😃

Lines 161 to 164 in 1be10ff

	- name: OVERRIDE_PV_CONFIG_WITH_IMAGE_CONFIG
	value: 'true'
	- name: OVERRIDE_PV_PLUGINS_WITH_IMAGE_PLUGINS
	value: 'true'

Environment variables in question: OVERRIDE_PV_CONFIG_WITH_IMAGE_CONFIG and OVERRIDE_PV_PLUGINS_WITH_IMAGE_PLUGINS. These should be unset or set to false.

I guess this should be moved to https://github.com/CentOS-PaaS-SIG/contra-env-infra. What is the usage for the jenkins-persistent-template.yaml.j2 template in this repository?

Correction, these envs need to be removed to have it working.

You don't have to use this Jenkins master config use your own or from contra-env-infra. This is here as an option. In fact I don't think we use this template any longer by default. It was for the CCIT team.
