Transparent Elasticsearch proxy

In this scenario, Quesma is used as a transparent proxy between Kibana/OpenSearchDashboards(OSD) and Elasticsearch/OpenSearch.

Quesma installation

Prerequisites:

• Elasticsearch/OpenSearch is running.
• Kibana/OSD is running.
• Docker is installed, at least 20.10 version.

Installation steps:

1. Create a configuration file named quesma.yaml with the following content, make sure to replace placeholders (#PLACE_YOUR*) with actual values.

   frontendConnectors:
     - name: elastic-ingest
       type: elasticsearch-fe-ingest
       config:
         listenPort: 8080
     - name: elastic-query
       type: elasticsearch-fe-query
       config:
         listenPort: 8080
   backendConnectors:
     - name: backend-elasticsearch
       type: elasticsearch
       config:
         url: #PLACE_YOUR_ELASTICSEARCH_URL_HERE, for example: http://192.168.0.7:9200
         user: #PLACE_YOUR_ELASTICSEARCH_USERNAME_HERE
         password: #PLACE_YOUR_ELASTICSEARCH_PASSWORD_HERE
   processors:
     - name: my-noop-processor
       type: quesma-v1-processor-noop
   pipelines:
     - name: elasticsearch-proxy-read
       frontendConnectors: [ elastic-query ]
       processors: [ my-noop-processor ]
       backendConnectors: [ backend-elasticsearch ]
     - name: elasticsearch-proxy-write
       frontendConnectors: [ elastic-ingest ]
       processors: [ my-noop-processor ]
       backendConnectors: [ backend-elasticsearch ]

Note: To learn more about configuration options, refer to Configuration primer

2. Run Quesma with the following command:

   docker run --name quesma -p 8080:8080 \
    -e QUESMA_CONFIG_FILE=/configuration/quesma.yaml \
   -v $(pwd)/quesma.yaml:/configuration/quesma.yaml quesma/quesma:latest

   You now have a running Quesma instance running with Elasticsearch API endpoint on port 8080. You can also enable Quesma's admin panel at localhost:9999 by adding -p 9999:9999 to docker run command.
3. Reconfigure client endpoint
   • For Kibana: Update your Kibana configuration, so that it points to Quesma Elasticsearch API endpoint mentioned above, instead of Elasticsearch original endpoint. In your Kibana configuration file, replace the elasticsearch.hosts value with Quesma's host and port, e.g.:

     elasticsearch.hosts: ["http://localhost:8080"]

     or optionally use ELASTICSEARCH_HOSTS environment variable.
   • For OpenSearchDashboards: modify opensearch_dashboards.yml file and change the opensearch.hosts property.
4. Restart Kibana/OSD.
