# Elasticsearch plug-ins
{: #plugins}

Elasticsearch supports many plug-ins to extend its core functions. IBM Cloud® Databases for Elasticsearch comes with a selection of plug-ins that already enabled on your deployment. Plug-in management is handled by the service, and users cannot install, uninstall, enable, or disable plug-ins.

You can check the plug-ins that are installed in your Elasticsearch cluster by using the `/_nodes/plugins` cluster API endpoint. Example, 
```sh
CURL_CA_BUNDLE=certificate.crt curl -u ibm_cloud_es_user:password https://f1b5e4a9-7179-4af2-a795-b7a0d71ec80a.974550db55eb4ec0983f023940bf637f.databases.appdomain.cloud:30909/_nodes/plugins
```
