Container Service for Kubernetes:CreateCluster

The custom cluster name. The name must be 1 to 63 characters in length and can contain digits, Chinese characters, letters, and hyphens (-). It cannot start with a hyphen (-).

The region ID of the cluster. For details, see Regions supported by container service.

• Kubernetes: ACK dedicated cluster.

After you set cluster_type to ManagedKubernetes and configure profile, you can further specify the cluster specification. Valid values:

• ack.standard: Basic Edition (selected by default if the value is left empty)

• ack.pro.small: Pro Edition

• ack.pro.xlarge: Pro XL

• ack.pro.2xlarge: Pro 2XL

• ack.pro.4xlarge: Pro 4XL (contact customer service to be added to the whitelist)

Pro XL, Pro 2XL, and Pro 4XL are three tiers provided by ACK Pro Provisioned Control Plane. These tiers pre-allocate and lock control plane resources to ensure that API concurrency and pod scheduling capabilities remain at a deterministic high level. They are suitable for AI training and inference, ultra-large-scale clusters, and mission-critical workloads.

For information about cluster management fees for Pro Edition and Provisioned Control Plane editions, see Cluster management fees.

If you set cluster_type to ManagedKubernetes, which indicates an ACK managed cluster, you can further specify the cluster subtype.

The cluster version, which is consistent with the Kubernetes community baseline version. We recommend that you select the latest version. If you do not specify this parameter, the latest version is used by default.

The resource group ID of the cluster, which is used to isolate different resources.

Specifies whether to enable deletion protection for the cluster. Deletion protection prevents the cluster from being accidentally deleted in the console or by calling API operations. Valid values:

• true: Enables deletion protection. The cluster cannot be deleted in the console or by calling API operations.

• false: Disables deletion protection. The cluster can be deleted in the console or by calling API operations.

Default value: false.

The VPC used by the cluster. You must provide a VPC when you create a cluster.

The IP protocol stack of the cluster.

The pod CIDR block. The value must be a valid private CIDR block, which includes the following CIDR blocks and their subnets: 10.0.0.0/8, 172.16-31.0.0/12-16, and 192.168.0.0/16. The pod CIDR block cannot overlap with the CIDR block of the VPC or the CIDR blocks used by existing Kubernetes clusters in the VPC. You cannot modify the pod CIDR block after the cluster is created.

For more information about cluster network planning, see Network planning for ACK managed clusters.

The Service network CIDR block. Valid ranges: 10.0.0.0/16-24, 172.16-31.0.0/16-24, and 192.168.0.0/16-24.

The security group ID. Specify this parameter when you use an existing security group to create a cluster. This parameter is mutually exclusive with is_enterprise_security_group. Cluster nodes are automatically added to this security group.

Specifies whether to enable automatic creation of an advanced security group. This parameter takes effect when security_group_id is empty.

Specifies whether to configure SNAT for the VPC. Valid values:

• true: Automatically creates a NAT gateway and configures SNAT rules. Set this to true if nodes and applications in the cluster need to access the Internet.

• false: Does not create a NAT gateway or SNAT rules. Nodes and applications in the cluster cannot access the Internet.

Default value: false.

Specifies whether to public network access. The API Server is exposed through an EIP to public network access to the cluster.

The CLB instance ID used for API Server access. When this parameter is specified, automatic creation of the API Server CLB is skipped.

Specifies whether to enable public SSH logon. This parameter is used to log on to master nodes of ACK dedicated clusters. This parameter does not take effect for managed clusters.

• true: Enabled.

• false: Disabled.

Default value: false.

The time zone used by the cluster. For more information, see Supported time zones.

The number of node IP addresses, determined by specifying the network CIDR block. This parameter takes effect only for Flannel network type clusters.

The kube-proxy proxy mode.

The number of days for control plane component log retention.

The Simple Log Service project for control plane component logs. You can use an existing project for log storage or allow the system to use automatic creation of a project. If you choose automatic creation, a Simple Log Service project named k8s-log-{ClusterID} is created.

The cluster local domain name.

The KMS key ID. This key is used to encrypt data cloud disks. For more information, see Key Management Service.

A ServiceAccount is the access credential for communication between a pod and the cluster API server. The service-account-issuer is the issuer identity in the serviceaccount token, which is the iss field in the token payload.

A ServiceAccount is the access credential for communication between a pod and the cluster API server. The api-audiences parameter specifies the valid request token identities used by the apiserver to authenticate whether a request token is valid. You can configure multiple audience values separated by commas (,).

The cluster maintenance window.

The custom cluster CA.

[Deprecated] Use the extra_sans parameter instead.

The container runtime of the cluster. Supported runtimes include containerd, sandboxed containers, and Docker.

[Deprecated] For node pool configuration, use the node_name_mode parameter under kubernetes_config in nodepool instead.

[Deprecated] The custom node data.

[Deprecated] For cluster control plane configuration, use the image_id parameter under control_plane_config instead. For node pool configuration, use the image_id parameter under scaling_group in nodepool instead.

[Deprecated] For cluster control plane node configuration, use the cloud_monitor_flags parameter under control_plane_config instead. For node pool configuration, use the cms_enabled parameter under kubernetes_config in the nodepool instead.

Specifies whether to install the CloudMonitor agent on the cluster. Valid values:

• true: Install the CloudMonitor agent.

• false: Do not install the CloudMonitor agent.

Default value: false.

[Deprecated] Use the platform parameter under scaling_group in nodepool instead for node pool configuration.

The operating system distribution. Valid values:

• CentOS

• AliyunLinux

• QbootAliyunLinux

• Qboot

• Windows

• WindowsCore

Default value: CentOS.

[Deprecated] For cluster control plane node configuration, use the image_type parameter under control_plane_config instead. For node pool configuration, use the image_type parameter under scaling_group in nodepool instead.

The operating system platform type. Valid values:

• Windows

• Linux

Default value: Linux.

[Deprecated] For cluster control plane node configuration, use the soc_enabled parameter under control_plane_config instead. For node pool configuration, use the soc_enabled parameter under scaling_group in nodepool instead.
