Allow imagePullPolicy override at the Plan.spec.upgrade level #380
Description
Is your feature request related to a problem? Please describe.
I preload my images into containerd in air-gapped environment. I am using the manifests provided where the environment variable "SYSTEM_UPGRADE_JOB_IMAGE_PULL_POLICY" is set to Always. This can be edited but I think it would be neat to be able to override that at the Plan.spec.upgrade level in case I know that the Plan I am running will have an image preloaded when there is no registry.
Describe the solution you'd like
When the option is run for upgrade container we should check if there is something set on the plan and if not use the default from either ENV or default value.
Describe alternatives you've considered
I understand I could just change the ENV default or not use the packaged manifest but this could add flexibility.
