1.1 Server requirements
Minimum hardware configuration: 2-core CPU, 2G memory, 20G hard disk, server network connection.
1.2 System environment
| system | Version |
|---|---|
| system environment | CentOS-7-x86_64 |
| Docker | 20-ce |
| Kubernetes | 1.23.0 |
| KubeSphere | 3.3.0 |
Centos installations are all minimal installations, and Gu requires the installation of net-tools tools:

yum install -y yum-utils
1.3 Server Node
| name of server | IP | Memory |
|---|---|---|
| master | 192.168.254.129 | 6G |
| node1 | 192.168.254.132 | 4G |
| node2 | 192.168.254.1321 | 4G |
