After you purchase an Alibaba Cloud Elasticsearch instance, the system displays preinstalled plug-ins in the Built-in Plug-ins list. Different instance versions support different plug-ins. Install or uninstall these plug-ins as needed. This topic describes the Elasticsearch versions compatible with each plug-in and how to install or uninstall built-in plug-ins.
Background information
For more information about the plug-ins supported by Alibaba Cloud Elasticsearch, their compatible versions, and supported operations, see Plug-in configuration. The analysis-ik and elasticsearch-repository-oss plug-ins are Alibaba Cloud Elasticsearch extensions and cannot be uninstalled by default. Details are as follows:
analysis-ik: an IK analysis plug-in. Based on the open source version, it supports dynamic loading of dictionary files from Object Storage Service (OSS). It supports both cold and rolling updates for IK dictionaries. For more information, see Use the IK analysis plug-in (analysis-ik).
elasticsearch-repository-oss: based on the open source version, this plug-in supports creating and restoring index snapshots using the OSS file system.
Precautions
Installing or uninstalling a plug-in triggers a cluster restart. Uninstalling a plug-in deletes the selected plug-in. Confirm your action and perform the operation during off-peak hours. Before uninstalling a plug-in, ensure that no index references it. If an index still references the plug-in, the cluster restart may stutter.
Procedure
Log on to the Alibaba Cloud Elasticsearch console.
In the left navigation menu, choose Elasticsearch Clusters.
Navigate to the target 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 navigation pane on the left, choose .
In the Built-in Plug-ins list, click Install or Remove in the Actions column for the target plug-in.
In the dialog box that appears, read the precautions, verify the details, and click OK.
After confirmation, the cluster restarts. During the restart, view task progress in the Tasks list. The plug-in installation or uninstallation completes after the restart succeeds.
