The current documentation of the OpenStack Charm Guide lacks a comprehensive list of essential services and their corresponding ports for various OpenStack services. This omission creates a significant gap for users and administrators aiming to achieve compliance with Rule 2.4 of the CIS (Center for Internet Security) Standard for Ubuntu 22.04, which mandates the management of open ports and associated services to ensure that only those that are necessary and critical are allowed.
