Replicated will pull all application images and push these images into a registry we host on-prem alongside your app. In the case of an airgapped installation, images are untarred from the bundle rather than being pulled from an upstream repository. All remote Replicated operators will then pull these images from the master registry rather than communicating directly with the internet. Replicated also uses this registry for disaster recovery.
