Response Parameters

Status code: 200

Table 4 Response body parameters

Parameter

Type

Description

kind

String

Api type

apiVersion

String

API version

items

Array of AutopilotCluster objects

A list of details for all clusters in the current project. You can find the corresponding clusters based on the value of items.metadata.name.

Table 5 AutopilotCluster

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

Element type of the collection class, which is used to record the statuses of an object in the system, including the cluster status and the ID of the cluster creation job

Table 6 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 7 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.

  1. Duplicate names are not allowed.

  2. 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

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.
