Network

On the Network tab, you can configure cluster and container CIDR blocks.

Cluster Network

Table 1 Parameters

Parameter

Description

VPC

The VPC where the cluster resides.

A VPC provides an isolated virtual network for cloud servers, cloud containers, and cloud databases. You can configure and manage the network as needed. You can configure a CIDR block for the VPC, create subnets, configure security groups, and even assign EIPs and allocate bandwidth in your network, enabling secure and easy access to your service system.

VPC CIDR Block

IP address range of the VPC for the cluster

Network Model

Only Cloud Native Network 2.0 is supported.

Service Settings

Service CIDR Block: IP address range of the ClusterIP Service in the cluster. The Service CIDR block cannot overlap with the container subnet CIDR block and can only be used in the cluster.

Container Network

If you need to set a different container subnet and security group for a namespace or workload, you can create a custom container network configuration and associate it with the namespace or workload. For details, see Associating a Subnet and Security Group with a Namespace or Workload Using a Container Network Configuration.

  • Associating with a subnet or CIDR block: Container IP addresses are allocated from this subnet or CIDR block. Only the containers in the same namespace or for running the same workload can communicate with each other.
  • Associating with a security group: You can configure security group rules for containers in the same namespace or for running the same workload to allow or deny traffic to and from the containers.

Container subnets can be deleted only when the CCE Autopilot cluster version is v1.27.8-r0, v1.28.6-r0, or later.
