Update CentOS-8-Container.ks
    
    Taking a complete shot in the dark here, but removing "--nobase" might be your issue. I had to remove it from my configs when going from 7 to 8. This PR also comments out the package exclusions, and I added the text/skipx both to eliminate potential problems. If this works, we can narrow down the issue pretty easily.

    

    Typically I'd also have "cdrom" but was told the repo URL is added dynamically.

    

    Also not sure why you have -iptables immediately followed by iptables.

    

    My package selection config for RHEL/Oracle 8 looks like:

    

    

    %packages --instLangs=en

    @core

    authconfig

    sudo

    %end
