This topic introduces the cloud controller manager (CCM) and provides usage notes and release notes for the component.
Introduction
- Manage CLB instances
If you set
Type=LoadBalancer
for a Service, the CCM automatically creates a CLB instance for the Service, and configures listeners and backend server groups. When the endpoint of an Elastic Compute Service (ECS) instance in a vServer group for a Service is changed or the cluster nodes are changed, the CCM automatically updates the vServer groups of the CLB instance. - Enable cross-node communication
If Flannel is used as the network plug-in of a Kubernetes cluster, the CCM can enable network connections between containers and nodes. This allows you to implement cross-node communication. The CCM adds the pod CIDR block to the route table of the VPC where the cluster is deployed. This enables cross-node communication. This feature is ready for use after the CCM is installed.
Usage notes
- The CCM automatically creates CLB instances for Services, and configures listeners and backend server groups. For more information, see Considerations for configuring a LoadBalancer type Service.
- The CCM allows you to add annotations in Service configurations to customize load balancing. For more information, see Use annotations to configure load balancing.
