Does Plesk support Elasticsearch?
Plesk doesn't provide a solution for Elasticsearch out of the box, which means that it is not possible to install Elasticsearch at the server directly by the means of Plesk.
Note: direct Elasticsearch installation at the server with Plesk had not been tested and Plesk cannot guarantee its stable work.
As an alternative, it is possible to install Elasticsearch Docker container via Plesk Docker Extension:
elasticsearchimage in the catalog, choose the required version and click on it.
