Runner configuration in Openshift with volume

I am trying to deploy a runner in Openshift. I have done it with Operators as it appears in the documentation, but I need to add a volume to add some files related to keys and so on.
Does anyone have any idea how to modify the Operator to support this modification, since changing the Deploy does not work and the changes there do not persist.
I know how to change the config.toml file to match the modification.

Thanks in advice
