Description
Controlling access to those users and roles that perform container platform registry functions reduces the risk of untested or potentially malicious containers from being introduced into the platform. This access may be separate from the access required to instantiate container images into services and those access requirements required to perform patch management and upgrades within the container platform. Explicit privileges (escalated or administrative privileges) provide the regular user with explicit capabilities and control that exceeds the rights of a regular user.
