After you purchase an Alibaba Cloud Elasticsearch cluster, built-in plug-ins are displayed on the Built-in Plug-ins tab. You can install or remove these plug-ins based on your business requirements. This topic describes how to install and remove a built-in plug-in for Alibaba Cloud Elasticsearch.
Background information
For more information about the plug-ins that are supported by Alibaba Cloud Elasticsearch, Elasticsearch versions in which the plug-ins are available, and the operations that are supported by the plug-ins, see Configure plug-ins. The analysis-ik and elasticsearch-repository-oss plug-ins are both extensions of Alibaba Cloud Elasticsearch. You cannot remove these plug-ins.
analysis-ik: an IK analysis plug-in. In addition to its open source features, this plug-in supports the dynamic loading of dictionaries stored in Object Storage Service (OSS). You can update dictionaries by using the standard update or rolling update method. For more information, see Use the analysis-ik plug-in.
elasticsearch-repository-oss: In addition to its open source features, this plug-in provides OSS storage while you create and restore index snapshots.
Precautions
If you install or remove a built-in plug-in, the cluster is restarted. Alibaba Cloud Elasticsearch removes only the plug-in that you select. Before you proceed, confirm the operation. We recommend that you install or remove a built-in plug-in during off-peak hours. In addition, if you want to remove a plug-in, you must make sure that the plug-in is not referenced by indexes. Otherwise, the cluster restart may be stuck.
Procedure
Log on to the Alibaba Cloud Elasticsearch console.
In the left-side navigation pane, click Elasticsearch Clusters.
Navigate to the desired cluster.
In the top navigation bar, select the resource group to which the cluster belongs and the region where the cluster resides.
On the Elasticsearch Clusters page, find the cluster and click its ID.
In the left-side navigation pane, click Plug-ins.
On the Built-in Plug-ins tab, find your desired plug-in and click Install or Remove in the Actions column.
Read the message that appears and click OK.
Then, the system restarts the cluster. During the restart, you can view the task progress in the Tasks dialog box.
