I followed the official helm chart for fluent-bit and ended up with 20 pods, in a namespace. How do I configure it to use 1 pod?
The replicaCount attribute in values.yaml is set to 1.

helm upgrade -i fluent-bit helm/efk/fluent-bit --namespace some-ns
kubectl get pods -n some-ns

This is controlled by the kind field of the values file.
Now daemonset is written in the values, so it will be on each node without considering the affinity Start a replica.
If you want to start one, please set kind to Deployment, then set replicaCount to 1 and redeploy.
values.yaml
# Default values for fluent-bit.
