Integrate with Elasticsearch

Use Olares Elasticsearch middleware by declaring it in OlaresManifest.yaml, then mapping the injected values to your container environment variables.

Install Elasticsearch service

Install the Elasticsearch service from Market.

1. Open Market from Launchpad and search for "Elasticsearch".
2. Click Get, then Install, and wait for the installation to complete.

Once installed, the service and its connection details will appear in the Middleware list in Control Hub.

Configure OlaresManifest.yaml

In OlaresManifest.yaml, add the required middleware configuration.

• Use the username field to specify the Elasticsearch user.
• Use the indexes field to request one or more indexes. Each index name is used as the key in .Values.elasticsearch.indexes.

Example

middleware:
  elasticsearch:
    username: elasticlient
    indexes:
      - name: aaa

Inject environment variables

In your deployment YAML, map the injected .Values.elasticsearch.* fields to the environment variables your app uses.

Example

containers:
  - name: my-app
    env:
      - name: ES_HOST
        value: "{{ .Values.elasticsearch.host }}"

      - name: ES_PORT
        value: "{{ .Values.elasticsearch.port }}"

      - name: ES_USER
        value: "{{ .Values.elasticsearch.username }}"

      - name: ES_PASSWORD
        value: "{{ .Values.elasticsearch.password }}"

      # Index name
      # The index name configured in OlaresManifest (for example, aaa)
      - name: ES_INDEX
        value: "{{ .Values.elasticsearch.indexes.aaa }}"

Elasticsearch Values reference

Elasticsearch Values are predefined environment variables injected into values.yaml during deployment. They are system-managed and not user-editable.

Key	Type	Description
.Values.elasticsearch.host	String	Elasticsearch service host
.Values.elasticsearch.port	Number	Elasticsearch service port
.Values.elasticsearch.username	String	Elasticsearch username
.Values.elasticsearch.password	String	Elasticsearch password
.Values.elasticsearch.indexes	Map<String,String>	The requested index name is used as the key. For example, if you request aaa, the value is available at .Values.elasticsearch.indexes.aaa.
