 ##### Control plane ee from private registry
-The images listed in "ee_images" will be added as globally available Execution Environments. The "control_plane_ee_image" will be used to run project updates. In order to use a private image for any of these you'll need to use `image_pull_secret` to provide a k8s pull secret to access it. Currently the same secret is used for any of these images supplied at install time.
