Reduce or Increase elastic nodes

Data nodes

In the example have 1 node of data declared in elastic-data.yaml, for increase only need add more replicas.

spec:
  serviceName: elasticsearch-data
  replicas: 1

Master Nodes

In the case of master elastic-master.yaml nodes you need update the replica param and the enviroment cluster.initial_master_nodes need add or remove the name of master nodes candidates.

spec:
  serviceName: elasticsearch-master
  replicas: 2
  
...
          env:
            - name: discovery.seed_hosts
              value: "elasticsearch-master.elk.svc.cluster.local"
            - name: cluster.initial_master_nodes
              value: "elasticsearch-master-0,elasticsearch-master-1" # necessarily have to match the number of replicas

Fluentd

You can change the elastisearch index pattern:

            - name: FLUENT_ELASTICSEARCH_LOGSTASH_INDEX_NAME
              value: "fluentd"
            - name: FLUENT_ELASTICSEARCH_LOGSTASH_PREFIX
              value: "fluentd"
