一、本次实践环境规划
| hostname | IP地址 | 操作系统版本 | k8s版本 | 角色 |
|---|---|---|---|---|
| k8s-master | 192.168.3.201 | centos7.6 | v1.23.1 | master节点 |
| k8s-node01 | 192.168.3.202 | centos7.6 | v1.23.1 | worker节点 |
| k8s-node02 | 192.168.3.203 | centos7.6 | v1.23.1 | worker节点 |
二、检查k8s环境
2.1检查工作节点状态
[root@k8s-master ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
k8s-master Ready control-plane,master 289d v1.23.1
k8s-node01 Ready <none> 289d v1.23.1
k8s-node02 Ready <none> 289d v1.23.12.2检查系统pod状态
[root@k8s-master ~]# kubectl get pods -n kube-system
NAME READY STATUS RESTARTS AGE
calico-kube-controllers-7bc6547ffb-2nf66 1/1 Running 18 (13m ago) 289d

kube-scheduler-k8s-master 1/1 Running 18 (13m ago) 289d三、编辑kanboard.yaml文件
3.1创建部署目录
mkdir -p /data/kanboard && cd /data/kanboard3.2编辑kanboard.yaml文件
vim kanboard.yaml
