Response Parameters

Status code: 200

**Table 4** Response body parameters
Parameter	Type	Description
kind	String	API type. The value is fixed at Cluster or cluster and cannot be changed.
apiVersion	String	API version. The value is fixed at v3 and cannot be changed.
metadata	AutopilotClusterMetadata object	Basic information about a cluster. Metadata is a collection of attributes.
spec	AutopilotClusterSpec object	Element type of the collection class. The main part of a cluster object to be managed is in spec. CCE creates or updates objects by defining or updating spec.
status	AutopilotClusterStatus object	Cluster status

**Table 5** AutopilotClusterMetadata
Parameter	Type	Description
name	String	Cluster name. Enter 4 to 128 characters starting with a lowercase letter and not ending with a hyphen (-). Only lowercase letters, digits, and hyphens (-) are allowed.
uid	String	Cluster ID, which uniquely identifies a resource. The value is automatically generated after the object is created. A custom value will not take effect. When you create a yearly/monthly cluster, no cluster ID will be returned in the response body.
alias	String	Alias of a cluster name displayed on the CCE console, and the name can be changed. Enter 4 to 128 characters starting with a lowercase letter and not ending with a hyphen (-). Only lowercase letters, digits, and hyphens (-) are allowed. A cluster alias must be unique. In the request body for creating or updating a cluster, if the cluster alias is not specified or is left blank, the alias of the cluster is the same as the cluster name. In the response body for creating a cluster, if the cluster alias is not configured, the cluster alias will not be returned.
annotations	Map<String,String>	Cluster annotations in the format of key-value pairs. "annotations": { "key1" : "value1", "key2" : "value2" } NOTE: Annotations are not used to label or select objects. The metadata in annotations may be small or large, structured or unstructured, and may include characters that are not allowed in labels. This field is not stored in the database and is used only to specify the add-ons to be installed in the cluster.
labels	Map<String,String>	Cluster labels in the format of key-value pairs. NOTE: The value of this field is automatically generated by the system and is used by the frontend to identify the features supported by a cluster during the upgrade. Customized values are invalid.
creationTimestamp	String	Time when a cluster was created
updateTimestamp	String	Time when a cluster was updated

**Table 6** AutopilotClusterSpec
Parameter	Type	Description
category	String	Cluster type. Only Turbo is supported.
type	String	Master node architecture. VirtualMachine: The master node is an x86 server.
flavor	String	Cluster specifications: cce.autopilot.cluster
version	String	Version of a cluster, which mirrors the baseline version of the Kubernetes community. The latest version is recommended. You can create clusters of the latest three versions on the CCE console. To learn which cluster versions are available, log in to the CCE console, create a cluster, and check supported cluster versions. You can call APIs to create clusters of other versions. However, these cluster versions will be gradually terminated. For details about the support policy, see the CCE announcement. NOTE: If not specified, a cluster of the latest version will be created.
platformVersion	String	CCE cluster platform version, which is an internal version under the cluster version (version). Platform versions are used to trace iterations in a major cluster version. They are unique within a major cluster version and recounted when the major cluster version changes. This parameter cannot be customized, and when you create a cluster, the latest corresponding platform version is selected automatically. The format of platformVersion is cce.X.Y. X: internal feature version, which indicates changes in features, patches, or OS support in the cluster version. The value starts from 1 and increases monotonically. Y: patch version of an internal feature version. It is used only for software package update after the feature version is released. No other modification is involved. The value starts from 0 and increases monotonically.
description	String	Cluster description, for example, which purpose the cluster is intended to serve. By default, this field is left blank. To modify cluster description after a cluster is created, call the API for updating a specified cluster or go to the cluster details page on the CCE console. Only UTF-8 encoding is supported.
customSan	Array of strings	The custom SAN field in the API server certificate of a cluster. It complies with the format specifications defined by the SSL standard X509. It is not supported by Autopilot clusters. Duplicate names are not allowed. The format must comply with the IP address and domain name formats. Example: SAN 1: DNS Name=example.com SAN 2: DNS Name=www.example.com SAN 3: DNS Name=example.net SAN 4: IP Address=93.184.216.34
enableSnat	Boolean	Whether SNAT is configured for a cluster. This parameter is used and returned only by the Autopilot cluster creation API. After this function is enabled, the cluster can access the Internet through a NAT gateway. By default, the existing NAT gateway in the selected VPC is used. Otherwise, the system automatically creates a NAT gateway of the default specifications, binds an EIP to the NAT gateway, and configures SNAT rules.
enableSWRImageAccess	Boolean	Whether a cluster is interconnected with SWR. This parameter is used and returned only by the Autopilot cluster creation API. To ensure that your cluster nodes can pull images from SWR, the existing SWR and OBS endpoints in the selected VPC are used by default. If not, new SWR and OBS endpoints will be automatically created.
enableAutopilot	Boolean	Whether the cluster is an Autopilot cluster
ipv6enable	Boolean	Whether a cluster uses the IPv6 mode. This parameter is not supported by Autopilot clusters.
hostNetwork	AutopilotHostNetwork object	Node networking parameters, including VPC and subnet ID. This field is mandatory because nodes in a cluster communicate with each other using a VPC.
containerNetwork	AutopilotContainerNetwork object	Container networking parameters, including the container network model and container CIDR block
eniNetwork	AutopilotEniNetwork object	Cloud Native 2.0 network settings
serviceNetwork	AutopilotServiceNetwork object	Service CIDR block, including IPv4 CIDR block
authentication	AutopilotAuthentication object	Configuration of the cluster authentication mode, which is not supported by Autopilot clusters
billingMode	Integer	Cluster billing mode 0: pay-per-use This parameter defaults to pay-per-use.
kubernetesSvcIpRange	String	Service CIDR block or the IP address range which the kubernetes clusterIP must fall within. If this parameter is not specified during cluster creation, the default value 10.247.0.0/16 is used. This parameter is being deprecated, so you can use serviceNetwork instead. The new field contains the IPv4 CIDR blocks.
clusterTags	Array of AutopilotResourceTag objects	Cluster resource tags
kubeProxyMode	String	Service forwarding mode. iptables: Traditional kube-proxy uses iptables rules to implement Service load balancing. In this mode, too many iptables rules will be generated when many Services are deployed. In addition, non-incremental updates will cause latency and even tangible performance issues in the case of service traffic spikes. NOTE: iptables is used by default.
az	String	AZ. This field is returned only for a query. For details about AZs supported by CCE, see Regions and Endpoints.
extendParam	AutopilotClusterExtendParam object	Extended field to decide whether a cluster will span across AZs or belong to a specified enterprise project, or whether a dedicated CCE cluster is to be created
configurationsOverride	Array of AutopilotPackageConfiguration objects	Overrides the default component configurations in a cluster. It is not supported in CCE Autopilot clusters.
