No.	Term	Description
1	Cluster	A cluster is a collection of cloud resources required to run a container, including several CVMs and CLBs. You can run your applications in a cluster.
2	Node	A node is a basic element of a container cluster. It can be either a virtual machine or a physical machine, depending on the service. Each node contains the basic components required to run a pod, including Kubelet and Kube-proxy.
3	Container	Docker containers allow you to run applications independently in an independent environment. Multiple containers can run in a node.
4	Image	Docker images are used to deploy TKS. Each image has a unique ID (image repository address + image name + image tag). Currently, Docker Hub official images and users' private images are supported.
5	Node pool	Nodes in a node pool have the same model, label, and taint attributes and can be dynamically scaled in or out. With these features, you can conveniently and quickly create, manage, and terminate nodes and dynamically scale nodes in and out.
6	Application	Kubernetes applications can run in a cluster. TKS allows you to create applications from the application market, third-party applications, and private applications.
