Cloud Container Engine (CCE)¶
CCE Cluster¶
Cloud Container Engine (CCE) is a highly reliable and high-performance service that allows enterprises to manage containerized applications. With support for Kubernetes-native applications and tools, CCE makes it simple to set up an environment for running containers in the cloud. CCE Clusters are the environment where cluster nodes are administrated. The core component is a Kubernetes Cluster with advanced features.

CCE Node Pool¶
A node pool is a group of one or more nodes with identical configuration in a cluster. In CCE, the nodes configured during cluster creation are grouped into the default node pool. The default node pool is named DefaultPool and cannot be edited, deleted, or migrated. In CCE SDK, you can create custom node pools in a cluster to organize cluster nodes into different pools so that you can edit or delete a node pool individually without affecting the entire cluster. All nodes in a custom node pool have identical parameters and node type. You cannot configure a single node in a node pool; any configuration changes affect all nodes in the node pool.
