I'm running syslog-ng-4.8.1-2.el8.x86_64  from the copr stable repository.

I'm trying to configure the kubernetes() source.

By compete configuration file is

@version: 4.8
@include 'scl.conf'
source s_k8s {
    kubernetes();
};

When I check this syntax

Error parsing config, syntax error, unexpected LL_IDENTIFIER, expecting '}' in /etc/syslog-ng/kubernetes.conf:7:5-7:15:
2       
3       @include 'scl.conf'
4       
5       
6       source s_k8s {
7----->     kubernetes();
7----->     ^^^^^^^^^^
8       };


I can't find any information on where the kubernets source is defined.
Is this defined in a scl include?
Do I need another rpm package?
Do I need to load a module?

What is my next step?
