Environment Requirements

This document provides guidance based on the Kunpeng server and openEuler OS. Before performing operations, ensure that your software and hardware meet the requirements.

Hardware Requirements

Table 1 lists the hardware requirements.

**Table 1** Hardware requirements
Category	Item	Requirements
Hardware	Server	Three Kunpeng servers
	CPU	Kunpeng 920
	NIC	TM210 with electrical ports

OS Requirements

Table 2 lists the OS requirements.

**Table 2** OS requirements
Item	How to Obtain
OS	Version: CentOS Linux release 7.6.1810 (AltArch) https://vault.centos.org/altarch/7.6.1810/isos/aarch64/ Version: openEuler-20.03-LTS https://www.openeuler.org/en/download/
Network	Docker Hub can be accessed: https://hub.docker.com/ The Docker download URL can be accessed: https://download.docker.com/linux/static/stable/aarch64/ Nodes in the cluster can access each other. The Flannel plugin code can be accessed: https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

When setting up a Kubernetes cluster, you need to install Docker and all Kubernetes components on each node.

Cluster Planning

A Kubernetes cluster consists of one management node (master) and multiple compute nodes (workers). Cluster creation and management are performed on the master node. Therefore, the master node and worker nodes must be on the same network and can communicate with each other. Figure 1 shows the planned cluster network.

Figure 1 K8s cluster network

Master is the cluster management node, and the workers are the cluster compute nodes.
At least two nodes are required to verify the cluster setup function. To verify the affinity scheduling function, at least three nodes are required. The installation and configuration must be performed on all nodes.
