DescribeKubernetesVersionMetadata - Container Service for Kubernetes

Queries the detailed information about Kubernetes versions, including the version number, release date, expiration date, compatible OSs, and runtime.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
cs:DescribeKubernetesVersionMetadata	get	All Resources *	none	none

Request syntax

GET /api/v1/metadata/versions HTTP/1.1

Request parameters

Parameter	Type	Required	Description	Example
Region	string	Yes	The region ID of the cluster.	cn-beijing
ClusterType	string	Yes	The cluster type that you want to use. Valid values: `Kubernetes`: ACK dedicated cluster. `ManagedKubernetes`: ACK managed cluster. ACK managed clusters include ACK Pro clusters, ACK Basic clusters, ACK Serverless Pro clusters, ACK Serverless Basic clusters, ACK Edge Pro clusters, and ACK Edge Basic clusters. `ExternalKubernetes`: registered cluster.	Kubernetes
KubernetesVersion	string	No	The Kubernetes version of the cluster. The Kubernetes versions supported by ACK are the same as the Kubernetes versions supported by open source Kubernetes. We recommend that you specify the latest Kubernetes version. If you do not set this parameter, the latest Kubernetes version is used. You can create ACK clusters of the latest two Kubernetes versions in the ACK console. You can call the specific ACK API operation to create clusters of other Kubernetes versions. For more information about the Kubernetes versions supported by ACK, see Release notes for Kubernetes versions.	1.16.9-aliyun.1
Profile	string	No	The scenario where clusters are used. Valid values: `Default`: non-edge computing scenarios `Edge`: edge computing scenarios `Serverless`: serverless scenarios. Default value: `Default`.	Default
runtime	string	No	The container runtime type that you want to use. You can specify a runtime type to query only OS images that support the runtime type. Valid values: `docker`: Docker `containerd`: containerd `Sandboxed-Container.runv`: Sandboxed-Container If you specify a runtime type, only the OS images that support the specified runtime type are returned. Otherwise, all OS images are returned.	docker
Mode	string	No	The query mode. Valid values: `supported`: queries all supported Kubernetes versions. `creatable`: queries only Kubernetes versions of clusters that you can create. If you specify `KubernetesVersion`, this parameter does not take effect. If you do not specify a query mode, Kubernetes versions of clusters that you can create are returned.	supported
QueryUpgradableVersion	boolean	No	Specify whether to query the Kubernetes versions available for updates. This parameter takes effect only when the KubernetesVersion parameter is specified.	1.30.1-aliyun.1
