es-data-generator-charm's Introduction

elasticsearch-data-provider

Description

This charm is meant only to test the Elasticsearch Operator charm. It will operate a container that generates random data for some period of time and then just wait in a loop (this is so users don't inadvertently add more data to ES than the host system(s) can handle).

Application source repository: https://github.com/justinmclark/elasticsearch-test-data
