Elasticsearch is a distributed, open source search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured.

Supported versions#

  • 6 (available for compatibility only, no longer officially supported) - uselagoon/elasticsearch-6
  • 7 Dockerfile - uselagoon/elasticsearch-7

Environment Variables#

Some options are configurable via environment variables.

Environment Variable Default Description
ES_JAVA_OPTS -Xms400m -Xmx400m Sets the memory usage of the Elasticsearch container. Both values need be the same value or Elasticsearch will not start cleanly.

Known issues#

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

elasticsearch_1  | ERROR: [1] bootstrap checks failed
elasticsearch_1  | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
