文章目录
介绍
- Kanboard是一个简介而强大的任务看板管理系统，它以敏捷开发理念为基础，皆在帮助个人和团队提高工作效率、优化工作流程。通过其直观的界面和灵活的配置选项，用户可以轻松地进行项目管理、任务分配、并跟踪进度
资源列表
| 操作系统 | 配置 | 主机名 | IP | k8s版本 |
|---|---|---|---|---|
| CentOS 7.9 | 2C4G | k8s-master | 192.168.93.101 | v1.18.0 |
| CentOS 7.9 | 2C4G | k8s-node01 | 192.168.93.102 | v1.18.0 |
| CentOS 7.9 | 2C4G | k8s-node02 | 192.168.93.103 | v1.18.0 |
基础环境
- 关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
- 关闭内核安全机制
setenforce 0
sed -i "s/^SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config
一、检查k8s环境
- 提前部署一个k8s集群，采用kubeadm或二进制安装都可以
1.1、检查工作节点状态
[root@k8s-master ~]# kubectl get node
NAME STATUS ROLES AGE VERSION
k8s-master Ready master 158m v1.18.0
k8s-node01 Ready <none> 157m v1.18.0
k8s-node02 Ready <none> 157m v1.18.0
1.2、检查系统pod状态
- 检查k8s集群中各系统组件的pod状态，确保都处于正常状态
[root@k8s-master ~]# kubectl get pod -n kube-system
NAME READY STATUS RESTARTS AGE
calico-kube-controllers-858fbfbc9-l8tpp 1/1 Running 1 157m
calico-node-k6qbl 1/1 Running 1 157m
calico-node-q969p 1/1 Running 1 157m
calico-node-sv48g 1/1 Running 1 157m
coredns-7ff77c879f-lnl72 1/1 Running 1 158m
coredns-7ff77c879f-nfx7g 1/1 Running 1 158m
etcd-k8s-master 1/1 Running 1 159m
kube-apiserver-k8s-master 1/1 Running 1 159m
kube-controller-manager-k8s-master 1/1 Running 1 159m
kube-proxy-2c282 1/1 Running 1 158m
kube-proxy-6n6pn 1/1 Running 1 158m
kube-proxy-zhm2m 1/1 Running 1 158m
kube-scheduler-k8s-master 1/1 Running 1 159m
二、编辑kanboard.yaml文件
- yaml文件直接复制粘贴即可
2.1、创建项目目录
[root@k8s-master ~]# mkdir -p /data/kanboard
[root@k8s-master ~]# cd /data/kanboard/
2.2、编辑kanboard.yaml文件
- 执行以下命令之前可以选择先导入需要的镜像，手动进行拉取，不然如果镜像拉去不下来的话，pod就会运行不起来，镜像拉取不下来的可以私信或者评论（开源）
[root@k8s-master kanboard]# vim kanboard.yaml

三、部署Kanboard
3.1、部署Kanboard服务
- 应用kanboard.yaml文件
[root@k8s-master kanboard]# kubectl apply -f kanboard.yaml
namespace/kanboard created
deployment.apps/kanboard created
service/my-kanboard created
3.2、检查pod状态
# 查看pod的详细信息
[root@k8s-master kanboard]# kubectl get pod -n kanboard -owide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
kanboard-7f447d6bd6-446rz 1/1 Running 0 32s 10.244.85.195 k8s-node01 <none> <none>
kanboard-7f447d6bd6-xtmbl 1/1 Running 0 32s 10.244.58.195 k8s-node02 <none> <none>
3.3、检查pod详细信息
- 查看kanboard的pod详细信息
[root@k8s-master kanboard]# kubectl describe pod -n kanboard kanboard-7f447d6bd6-446rz
Name: kanboard-7f447d6bd6-446rz
Namespace: kanboard

3.4、查看service状态
- 检查service状态。kanboard的外部访问端口为30080和30090
# servcie简称svc
[root@k8s-master kanboard]# kubectl get svc -n kanboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
my-kanboard NodePort 10.109.78.136 <none> 80:30080/TCP,443:30090/TCP 2m59s
