Kubernetes Fluentd Integration with Elasticsearch

My Elasticsearch is deployed on a single machine, so to connect Kubernetes Fluentd to Elasticsearch, I need to modify some configuration items.

First, install Fluentd on Kubernetes.
Download the YAML template repository:

git clone https://github.com/fluent/fluentd-kubernetes-daemonset

Modify the fluentd-daemonset-elasticsearch-rbac.yaml file, replacing

        env:
          - name:  FLUENT_ELASTICSEARCH_HOST
            value: "elasticsearch-logging"
          - name:  FLUENT_ELASTICSEARCH_PORT
            value: "9200"
          - name: FLUENT_ELASTICSEARCH_SCHEME
            value: "http"
          # Option to configure elasticsearch plugin with self signed certs
          # ================================================================
          - name: FLUENT_ELASTICSEARCH_SSL_VERIFY
            value: "true"
          # Option to configure elasticsearch plugin with tls
          # ================================================================
          - name: FLUENT_ELASTICSEARCH_SSL_VERSION
            value: "TLSv1_2"
          # X-Pack Authentication
          # =====================
          - name: FLUENT_ELASTICSEARCH_USER
            value: "elastic"
          - name: FLUENT_ELASTICSEARCH_PASSWORD
            value: "changeme"

elasticsearch-logging is the address of Elasticsearch.

Then apply the YAML file directly.
