Installing an Add-on Instance

Function

This API is used to install an add-on instance by using the add-on template. One or more instances will be created for the installed add-on.

The URL for add-on management is in the format of https://{clusterid}.Endpoint/uri. In the URL, {clusterid} indicates the cluster ID, and uri indicates the resource path, that is, the path for API access.

URI

POST /api/v3/addons

Request

Request parameters:

Table 1 lists the request parameters.

**Table 1** Parameters in the request header
