About Elasticsearch

Elasticsearch is a full-text search system built on Apache Lucene. It can be used to index and search data stored as JSON documents.

Elasticsearch is the technology used to power Wikimedia's CirrusSearch system.

Elasticsearch for Toolforge

An Elasticsearch version 7 cluster for all tools is available at, on the non-standard port 80.

This Elasticsearch cluster is a shared resource. All documents indexed in it can be read by anonymous users from within Toolforge. Write access is needed to create new indexes, and a password is needed to store or update documents.

Read-only access

The Elasticsearch servers allow anyone to read any of the indexes that it contains. This access is limited to other hosts in the Toolforge project (e.g. the OGE job grid, Kubernetes containers, and the bastion servers).

The Elasticsearch service is available on port 80 at

Note: The default Elasticsearch port (9200) is not used.

Write access

Elasticsearch does not offer multi-tenant access control in its open source version.

PUT, POST, or DELETE requests sent to the Elasticsearch servers require HTTP Basic Authentication using a username and password specific to each tool.

Requests for write access can be made by filing this Phabricator task.

When credentials have been created they will be placed in /data/project/$TOOL/.elasticsearch.ini. Access requests are currently processed manually and may take a few days to be fulfilled.
