download https://raw.githubusercontent.com/fluent/fluent-bit-kubernetes-logging/master/output/elasticsearch/fluent-bit-ds.yaml

update the yaml file: 

 fluent-bit-ds.yaml  apiVersion: apps/v1  ...  selector:   matchLabels:     name: fluent-bit  template:   metadata:     labels:      name: fluent-bit  ...  env: - name: FLUENT_ELASTICSEARCH_HOST value: "10.97.24.124" - name: FLUENT_ELASTICSEARCH_PORT value: "19200"  ... 

kubectl create -f  fluent-bit-ds.yaml
