Function

This API is used to obtain the agent installation script of a multi-cloud cluster.

Calling Method

For details, see Calling APIs.

URI

GET /v5/{project_id}/container/kubernetes/multi-cloud/clusters/{cluster_id}/agent/install-script

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Definition Project ID, which is used to specify the project that an asset belongs to. After the project ID is configured, you can query assets in the project using the project ID. For details about how to obtain it, see Obtaining a Project ID. Constraints N/A Range The value can contain 1 to 256 characters. Default Value N/A
cluster_id	Yes	String	Cluster ID

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
enterprise_project_id	No	String	Definition Enterprise project ID, which is used to filter assets in different enterprise projects. For details, see Obtaining an Enterprise Project ID. To query assets in all enterprise projects, set this parameter to all_granted_eps. Constraints You need to set this parameter only after the enterprise project function is enabled. Range The value can contain 1 to 256 characters. Default Value 0: default enterprise project.

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Definition User token, which contains user identity and permissions. The token can be used for identity authentication when an API is called. For details about how to obtain the token, see Obtaining a User Token. Constraints N/A Range The value can contain 1 to 32,768 characters. Default Value N/A

Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
install_script	String	Agent installation script
