Pls make vedio on server patching using redhat satellite server

[@NehraClasses]

Satellite server requires at least 12 GB of RAM & redhat subscription

[@ejajinamdar8973]

@@NehraClasses is there any alternative option to learn server patching in real production enviourment

[@NehraClasses]

Katello is the open source alternative of Satellite but it also requires 12 GB RAM.
