Kibana Config
Kibana configuration is easily customizable using helm as well kubectl. Since all the configurations are in the form YAML file, it can be easily changed and customized.
The values.yaml file for Kibana setup can be found here. But if the setup is not done using Helm, in that case Kubernetes manifests needs to be customized.

CRD object definition parameters
These are the parameters that are currently supported by the Logging Operator for the Kibana setup:-
- replicas
- esCluster
- esSecurity
- kubernetesConfig
replicas
replicas is field definition of Kibana CRD in which we can define how many replicas/instances of Kibana we would like to run. Similar field like replicas in deployment and replicasets.
replicas: 1
esCluster
esCluster is a general parameter of Fluentd CRD for providing the information about Elasticsearch nodes.
esCluster:
host: https://elasticsearch-master:9200
esVersion: 7.16.0
clusterName: elasticsearch
esSecurity
esSecurity s the security specification for Fluentd CRD. If we want to enable authentication and TLS, in that case, we can enable this configuration. To enable the authentication we need to provide secret reference in Kubernetes.
esSecurity:
tlsEnabled: true
existingSecret: elasticsearch-password
kubernetesConfig
kubernetesConfig is the general configuration paramater for Fluentd CRD in which we are defining the Kubernetes related configuration details like- image, tag, imagePullPolicy, and resources.
kubernetesConfig:
resources:
requests:
cpu: 100m
memory: 100Mi
limits:
cpu: 2000m
memory: 2Gi
