Some companies have security policy to use local docker images instead of getting latest images from internet. When docker image is pulled in localization phase, there are two possible out comes. The image is getting the latest from trusted registries, or the image is a static local copy. This task is to add a configuration flag to give priority to local image over trusted registry image.
If a image already exist locally, node manager does not trigger docker pull to get the latest image from trusted registries.
