Plugins extend the core functionality of Elasticsearch. There are many suitable plugins, including:
- The discovery plugins, such as the cloud AWS plugin that allows discovering nodes on EC2 instances
- The analysis plugins, to provide analyzers targeted at languages other than English
- The scripting plugins, to provide additional scripting languages
Plugins can come from different sources: The official ones created or at least maintained by Elastic, community-sourced plugins from other users, and plugins that you provide. Some of the official plugins are always provided with our service and you just have to add them to your cluster.
There are two ways to add plugins to a cluster in Elasticsearch Service:
- Select one of the official plugins already available in Elasticsearch Service.
- Upload a custom plugin and then install it on your cluster.
Custom plugins can include the official Elasticsearch plugins not provided with Elasticsearch Service, any of the community-sourced plugins, or plugins that you write yourself. Uploading custom plugins is available only to Gold and Platinum subscriptions. For more information, see Uploading Custom Plugins, Dictionaries, and Scripts.
To learn more about what official and community-sourced plugins are available, see Elasticsearch Plugins and Integrations.
We make it easy to add plugins to your Elasticsearch cluster by providing a variety of compatible plugins that work with your version of Elasticsearch. One advantage of the official plugins is that you generally don’t have to worry about also upgrading plugins when you upgrade to a new Elasticsearch version, unless there are breaking changes. The plugins simply are upgraded along with the rest of your cluster.
To add a plugin:
- Log into the Elasticsearch Service Console.
On the Deployments page, select your deployment.
Narrow your deployments by name, ID, or choose from several other filters. To customize your view, use a combination of filters, or change the format from a grid to a list.
- From your deployment menu, go to the Edit page.
- Beneath the Elasticsearch master node, expand the Advanced Elasticsearch caret.
- Select the plugins that you want.
- Click Save changes. The cluster is then updated with new nodes that have the plugin installed.
Different versions of Elasticsearch support different plugins.
There are some restrictions that apply to plugins with Elasticsearch Service:
- Kibana plugins are not supported.
- Some Elasticsearch plugins do not apply to the Elasticsearch Service. For example, you won’t ever need to change discovery, as Elasticsearch Service handles how nodes discover one another.
- In Elasticsearch 1.x, custom plugins are not available. If you need a custom plugin, use a supported Elasticsearch version.
- In Elasticsearch 5.0 and later, site plugins are no longer supported. This change does not affect the site plugins Elasticsearch Service might provide out of the box, such as Kopf or Head, since these site plugins are serviced by our proxies and not Elasticsearch itself.
- In Elasticsearch 6.0 and later, site plugins such as Kopf and Paramedic are no longer provided. We recommend that you either use our cluster performance metrics or enable the X-Pack monitoring features if you want more detailed information.
