Kubernetes resources to deploy Fluent Bit.
In this repository you will find the basic Kubernetes resources to deploy Fluent Bit on Kubernetes out of the HELM world.
A really cool tool to manage Kubernetes resources is K9S which I recommend
Will deploy Fluent Bit v1.5 over 3 replicas
Contains only a simple INPUT and OUTPUT plugins. The input reads from TCP and the OUTPUT just displays what was received over the standard output, which is the logs.
Just to expose the deployment, as ClusterIP, and the ports.
kubectl apply -f ./
Once is up, you will see in the Fluent Bit logs something like

Once the resources are deployed, you can do port-forwarding to port tcp:5170 to your localhost. Once done, you can run
echo '{"key 1": 123456789, "key 2": "abcdefg"}' | nc 0.0.0.0 5170
And you will in the Fluent Bit logs something like this:
[0] tcp.0: [1597853873.242894573, {"key 1"=>123456789, "key 2"=>"abcdefg"}]
kubectl delete -f ./
