Overview

A plugin is used to enhance the core functionalities of Elasticsearch. Elasticsearch provides some cadre plugins every bit a part of their release installation. In add-on to those core plugins, it is possible to write your own custom plugins too. There are several community plugins available on GitHub for various use cases.

Examples

sudo bin/elasticsearch-plugin -h

Installing the S3 plugin for storing Elasticsearch snapshots on S3:

sudo bin/elasticsearch-plugin install repository-s3

Removing a plugin:

sudo bin/elasticsearch-plugin remove repository-s3

Installing a plugin using the file'due south path:

sudo bin/elasticsearch-plugin install file:///path/to/plugin.zip

Notes and good things to know

• Plugins are installed and removed using the elasticsearch-plugin script, which ships as a role of the Elasticsearch installation and can exist found within the bin/ directory of the Elasticsearch installation path.
• A plugin has to be installed on every node of the cluster and each of the nodes has to be restarted to brand the plugin visible.
• You can likewise download the plugin manually and then install it using the elasticsearch-plugin install command, providing the file proper noun/path of the plugin'due south source file.
• When a plugin is removed, yous will need to restart every Elasticsearch node in order to consummate the removal procedure.

Common issues

• Managing permission issues during and after plugin installation is the almost common problem. If Elasticsearch was installed using the DEB or RPM packages so the plugin has to exist installed using the root user. Otherwise you can install the plugin as the user that owns all of the Elasticsearch files.
• In the case of DEB or RPM package installation, information technology is important to bank check the permissions of the plugins directory afterward you install it. Yous can update the permission if it has been modified using the following command:

chown -R elasticsearch:elasticsearch path_to_plugin_directory        

• If your Elasticsearch nodes are running in a private subnet without internet access, you cannot install a plugin directly. In this instance, you can simply download the plugins and copy the files within the plugins directory of the Elasticsearch installation path on every node. The node has to be restarted in this instance as well.
