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.
Note
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
