Preparing the Environment

You can start video stream cloud phones with containerd and manage them as a Kubernetes cluster. To deploy video stream cloud phones in a Kubernetes cluster, at least two servers are required. One server functions as the master node, and the others function as worker nodes.

Table 1 describes the node planning.

**Table 1** Kubernetes cluster nodes
Node Name (host name, which can be customized)	Node Role	Number of Servers	Environment Preparation	Node Function
k8s-master	Master node	1	Install openEuler 22.03 LTS SP1 on the Kunpeng server.	Coordinates and manages various resources in the cluster to achieve high availability, high scalability, and automatic O&M. This node does not run cloud phone services.
k8s-slave1	Worker node	≥ 1	You can deploy the environment based on Software Deployment.	Runs cloud phone services.

Kubernetes is a container orchestration platform. The worker nodes need to run cloud phone services. Before deploying Kubernetes or after restarting a node, ensure that the video stream cloud phone environment has been deployed on the worker nodes. You can start a video stream cloud phone to check whether the environment deployment is complete.
To deploy a Kubernetes cluster environment and images, you need to pull images from the Docker image repository. Ensure that the server network is able to pull images from the Docker image repository.
