Creating a Cluster

Function

This API is used to create an empty cluster, which has only master nodes but do not have worker nodes. After creating a cluster by calling this API, you can add nodes to the cluster. For details, see Creating a Node.

Note

  • The URL for cluster management is in the format of https://Endpoint/uri. In the URL, uri indicates the resource path, that is, the path for API access.

  • Info collect agent (ICAgent) is an O&M data collection agent. It runs on each server to collect data from probes in real time. When this API is called to create a cluster, ICAgent is not installed by default. To automatically install ICAgent during cluster creation, add "cluster.install.addons.external/install": "[{\"addonTemplateName\":\"icagent\"}]" to the annotations field in the request body.

  • Before creating a cluster, Creating a VPC and Subnet. If a VPC and subnet already exists, you do not need to create them again.

  • By default, an account can create a maximum of five clusters in each region.

version

No

String

Cluster version, which mirrors the baseline version of the Kubernetes community. The latest version is recommended.

You can create clusters of two latest versions on the CCE console. To learn which cluster versions are available, choose Dashboard > Create Cluster on the CCE console and check the Version parameter.

You can call APIs to create clusters of other versions. However, these clusters will be gradually brought offline. For details about the offline policy, see the official CCE announcement.

Note

If this parameter is not set, the cluster of the latest version is created by default.

Table 9 Data structure of the authenticatingProxy field

Parameter

Mandatory

Type

Description

ca

No

String

X509 CA certificate (Base64-encoded) configured in authenticating_proxy mode. This field is mandatory when the cluster authentication mode is authenticating_proxy. The maximum size of the certificate is 1 MB.

Note

The uploaded CA certificate is used for both the authentication proxy and the kube-apiserver aggregation layer configuration. If the certificate is invalid, the cluster cannot be created. For details about the kube-apiserver aggregation layer, see Configure the Aggregation Layer.

cert

No

String

Client certificate (Base64-encoded) issued by the X509 CA certificate configured in authenticating_proxy mode. This certificate is used for authentication from kube-apiserver to the extended API server. This field is mandatory when the cluster authentication mode is authenticating_proxy.

For details about the kube-apiserver aggregation layer, see Configure the Aggregation Layer.

privateKey

No

String

Private key (Base64-encoded) of the client certificate issued by the X509 CA certificate configured in authenticating_proxy mode. This key is used for authentication from kube-apiserver to the extended API server. The private key used by the Kubernetes cluster does not support password encryption. Use an unencrypted private key. This field is mandatory when the cluster authentication mode is authenticating_proxy.

For details about the kube-apiserver aggregation layer, see Configure the Aggregation Layer.

Table 10 Data structure of the containerNetwork field

Parameter

Mandatory

Type

Description

mode

Yes

String

Container network model. Select one of the following possible values:

  • overlay_l2: an overlay_l2 network built for containers by using OpenVSwitch (OVS).

  • vpc-router: an underlay_l2 network built for containers by using ipvlan and custom VPC routes.

  • eni: cloud native 2.0 network model. This model deeply integrates the native ENI capability of VPC, uses the VPC CIDR block to allocate container addresses, and supports passthrough between load balancers and containers to provide high performance. You can use this network model when creating a CCE Turbo cluster.

Note

  • Tunnel network: Under this model, the container network is an overlay network on top of a VPC network based on the VXLAN technology. VXLAN encapsulates Ethernet packets as UDP packets for tunnel transmission. Though at some cost of performance, the tunnel encapsulation enables higher interoperability and compatibility with advanced features (such as network policy-based isolation), meeting the requirements of most applications.

  • VPC network: Routing is implemented within a VPC network according to custom VPC routes. Each node is assigned a CIDR block of a fixed size. vpc-router networks are free of tunnel encapsulation overheads and provide better container network performance than tunnel networks. In addition, as routes to node IP addresses and the containers have been configured on vpc-router, container instances can be directly accessed from outside the cluster.

cidr

No

String

Container CIDR block. Recommended: 10.0.0.0/12-19, 172.16.0.0/16-19, or 192.168.0.0/16-19. If the selected CIDR block conflicts with existing CIDR blocks, the system automatically selects another CIDR block.

This parameter cannot be modified after the cluster is created. Exercise caution when setting this parameter.(This parameter has been discarded. If cidrs has been configured, skip this parameter.)

Minimum: 0

Maximum: 64

Note

This parameter is not valid for CCE Turbo cluster.

cidrs

No

Array of ContainerCIDR objects

List of container CIDR blocks. In clusters of v1.21 and later, the cidrs field is used. When the cluster network type is vpc-router, you can add multiple container CIDR blocks. In versions earlier than v1.21, if the cidrs field is used, the first CIDR element in the array is used as the container CIDR block.

The configuration cannot be changed after the cluster is created.

Parameter

Mandatory

Type

Description

clusterAZ

No

String

If you want to enable multiple AZs for the cluster, enter {"clusterAZ": "multi_az"}.

Note

Only HA clusters support multiple AZs. To be specific, this field can be configured only when the flavor field in Table 5 is set to cce.s2.small, cce.s2.medium, cce.s2.large, cce.t2.small, cce.t2.medium, or cce.t2.large.

The value is an integer ranging from 24 to 28.

kubernetes.io/cpuManagerPolicy

No

String

Cluster CPU management policy. The value can be none or static. The default value is none.

  • none: CPU cores will not be exclusively allocated to workload pods. Select this value if you want a large pool of shareable CPU cores.

  • static: CPU cores can be exclusively allocated to workload pods. Select this value if your workload is sensitive to latency in CPU cache and scheduling.

upgradefrom

dssMasterVolumes

String

Whether the system and data disks of a master node use dedicated distributed storage. If this parameter is omitted or left unspecified, EVS disks are used by default.

kubeProxyMode

String

Service forwarding mode. Two modes are available:

  • 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 a latency and even tangible performance issues in the case of service traffic spikes.

  • ipvs: Optimized kube-proxy mode with higher throughput and faster speed. This mode supports incremental updates and can keep connections uninterrupted during service updates. It is suitable for large-sized clusters.

clusterExternalIP

String

EIP used to access the cluster.

alpha.cce/fixPoolMask

String

Number of mask bits of the fixed IP address pool of the container network model. This field is supported only for the VPC network model (vpc-router).

This parameter determines the number of container IP addresses that can be allocated to a node. The maximum number of pods that can be created on a node is decided by this parameter and maxPods set during node creation.

The value is an integer ranging from 24 to 28.

kubernetes.io/cpuManagerPolicy

String

Cluster CPU management policy. The value can be none or static. The default value is none.

  • none: CPU cores will not be exclusively allocated to workload pods. Select this value if you want a large pool of shareable CPU cores.

  • static: CPU cores can be exclusively allocated to workload pods. Select this value if your workload is sensitive to latency in CPU cache and scheduling.

upgradefrom

String

Reserved. This field is returned only for a query.

  • ScalingUp: Nodes are being added to the cluster.

  • ScalingDown: The cluster is being downsized to fewer nodes.

  • Creating: The cluster is being created.

  • Deleting: The cluster is being deleted.

  • Upgrading: The cluster is being upgraded.

  • Empty: The cluster has no resources.

jobID

String
