OpenSearch is a community-driven, Apache 2.0-licensed open source search and analytics suite that makes it easy to ingest, search, visualize, and analyze data.

Supported versions#

Environment Variables#

Some options are configurable via environment variables.

Environment Variable Default Description
OPENSEARCH_JAVA_OPTS -Xms512m -Xmx512m Sets the memory usage of the OpenSearch container. Both values need be the same value or OpenSearch will not start cleanly.

Known issues#

On Linux-based systems, the start of the OpenSearch container may fail due to a low vm.max_map_count setting.

opensearch_1  | ERROR: [1] bootstrap checks failed
opensearch_1  | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
