Hi all, I was wondering if it was possible to compose a fluentbit configuration from both a ClusterFluentBitConfig and several FluentBitConfig. My use case is a cluster where I have several namespaces, one for each tenant, and each of the tenants have their own elasticsearch ingest credentials. So the result I'm after is a single fluentbit daemonset, in my namespace, fetching all the Output configurations from the other namespaces. Is this possible? I don't find any examples in the documentation

Looking further in the code, it should work. I'm debugging and it fails in my case as the operator isn't fetching the namespaced FluentBitConfig.

Found my issue The

spec.namespaceFluentBitCfgSelector

<http://fluentbit.v1alpha2.fluentbit.fluent.io|fluentbit.v1alpha2.fluentbit.fluent.io>

is not supposed to express label selectors for the namespace where the

FluentBitConfig

lives, but instead for the labels of the

FluentBitConfig

itself. With regards to that, the

FluentBit

CRD description of the field could be updated, as it currently may be missleading

NamespacedFluentBitCfgSelector selects the namespace FluentBitConfig associated with this FluentBit

Notice it says namespace - rather than namespaced. This can make people think about the label filtering being applied to the namespace itself (that contains FluentBitConfig resources) rather than the the labels in the namespaced resouce itself
