+
+#or
+
+Gitlab::CurrentSettings.elasticsearch_indexing

+
+```ruby
+es_url = Gitlab::CurrentSettings.current_application_settings
+
+# Confirm the current Elasticsearch URL
+es_url.elasticsearch_url
+
+# Set the Elasticsearch URL
+es_url.elasticsearch_url = "http://<username>:<password>@your.es.host:<port>"
