Why use OpenSearch?

OpenSearch is well-suited to the following use cases:

  • Log analytics
  • Real-time application monitoring
  • Clickstream analytics
  • Search backend
Component Purpose
OpenSearch Data store and search engine
OpenSearch Dashboards Search frontend and visualizations
Security Authentication and access control for your cluster
Alerting Receive notifications when your data meets certain conditions
SQL Use SQL or a piped processing language to query your data
Index State Management Automate index operations
KNN Find “nearest neighbors” in your vector data
Performance Analyzer Monitor and optimize your cluster

Docker quickstart

Docker

  1. Install and start Docker Desktop.
  2. Run the following commands:

    docker pull opensearchproject/opensearch:1.0.1
    docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:1.0.1
    
  3. In a new terminal session, run:

    curl -XGET --insecure https://localhost:9200 -u admin:admin
    

To learn more, see Install and configure OpenSearch and Install and configure OpenSearch Dashboards.

The secure path forward

OpenSearch includes a demo configuration so that you can get up and running quickly, but before using OpenSearch in a production environment, you must configure the security plugin manually: your own certificates, your own authentication method, your own users, and your own passwords.
