【云原生】Kubernetes部署Kanboard项目管理平台

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

      containers: 
      - image:   kanboard/kanboard:v1.2.26
        name: my-kanboard
        ports:

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

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

四、访问Kanboard平台

• 访问地址：http://192.168.93.101:30080

• 访问地址：http://192.168.93.101:30090

• 用户名admin、登录密码：admin
  
  

• 接下来就可以尽情的去研究啦！！！
