Description
Controlling access to those users and roles responsible for patching and updating the container platform reduces the risk of untested or potentially malicious software from being installed within the platform. This access may be separate from the access required to install container images into the registry and those access requirements required to instantiate an image into a service. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user.
