No

true

Specifies whether to allow the cluster to access the API server over the Internet. Valid values:

Default value: true.

service_discovery_types

Array of String

No

PrivateZone

The type of service discovery that is implemented in the ACK Serverless cluster. Valid values:

• CoreDNS: a Kubernetes-native standard service discovery component. You must deploy a set of containers to use the DNS resolution service. By default, two elastic container instances (ECIs) that have 0.25 CPU cores and 512 MiB of memory are used.

• PrivateZone: a DNS resolution service provided by Alibaba Cloud. You must activate Alibaba Cloud DNS PrivateZone before you can use it for service discovery.

By default, this parameter is not specified.

zoneid

String

No

logging_type

String

No

SLS

Specifies whether to enable Simple Log Service for the cluster. Set the value to SLS. This parameter takes effect only for ACK Serverless clusters.

tags

Array of tag

No

[{"key": "env", "value": "prod"}]

The tags that you want to add to the cluster. A tag consists of the following elements:

• key: the tag key.

• value: the tag value.

deletion_protection

Boolean

No

true

Specifies whether to enable deletion protection for the cluster. After deletion protection is enabled, the cluster cannot be deleted in the ACK console or by calling API operations. Valid values:

• true: enables deletion protection for the cluster.

• false: disables deletion protection for the cluster.

Default value: false.

service_cidr

String

No

172.21.0.0/20

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

The Service CIDR block cannot overlap with the VPC CIDR block or the CIDR blocks of existing clusters in the VPC. The VPC CIDR block is 10.1.0.0/21. You cannot modify the Service CIDR block after the cluster is created.

Default value: 172.19.0.0/20.

timezone

String

No

Asia/Shanghai

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

The components that you want to install in the cluster. You can specify the following parameters:

• name: required. This parameter indicates the name of the component.

• config: optional. If this parameter is left empty, no configurations are required.

• disabled: optional. This parameter specifies whether to disable automatic installation.

Network plug-in: required. You can select Flannel or Terway when you create the cluster.

• Specify the Flannel plug-in in the following format: [{"name":"flannel","config":""}].

Volume plug-in: optional. Set the value to csi.

Specify the CSI plug-in in the following format: [{"name":"csi-plugin","config": ""},{"name": "csi-provisioner","config": ""}].

Log Service component: optional.

• To use an existing Simple Log Service project, specify the component in the following format: [{"name": "logtail-ds","config": "{\"IngressDashboardEnabled\":\"true\",\"sls_project_name\":\"your_sls_project_name\"}"}].

• To create a Simple Log Service project, specify the component in the following format: [{"name": "logtail-ds","config": "{\"IngressDashboardEnabled\":\"true\"}"}].

Ingress controller: optional. By default, the nginx-ingress-controller component is installed in ACK dedicated clusters.

• To install nginx-ingress-controller and enable Internet access, specify the Ingress controller in the following format: [{"name":"nginx-ingress-controller","config":"{\"IngressSlbNetworkType\":\"internet\"}"}].

• If you do not want to install nginx-ingress-controller, specify the component in the following format: [{"name": "nginx-ingress-controller","config": "","disabled": true}.

Event center: optional. By default, the event center feature is enabled. You can use Kubernetes event centers to store and query events and configure alerts.

your_sls_project_name\"}"}].

snat_entry

Boolean

No

true

Specifies whether to create a NAT gateway and configure Source Network Address Translation (SNAT) rules when you create the ACK Serverless cluster. Valid values:

• true: automatically creates a NAT gateway and configures SNAT rules. If you set this parameter to true, the cluster in the VPC can access the Internet.
