云原生Kubernetes: K8S 1.29版本部署Kuboard

作者：不正经 | 2024-04-26 07:03:31

踩

一、实验

1.环境

2.K8S 1.29版本部署Kuboard (第一种方式)

3.K8S 1.29版本部署Kuboard (第二种方式)

4.K8S 1.29版本使用Kuboard

二、问题

1.docker如何在node节点间移动镜像

一、实验

1.环境

（1）主机

表1 主机

主机	架构	版本	IP	备注
master	K8S master节点	1.29.0	192.168.204.8
node1	K8S node节点	1.29.0	192.168.204.9
node2	K8S node节点	1.29.0	192.168.204.10

（2）master节点查看集群


1）查看node
kubectl get node
 
2)查看node详细信息
kubectl get node -o wide

2.K8S 1.29版本部署Kuboard (第一种方式)

（1）查阅


1）官网
https://kuboard.cn/
 
2）安装说明
https://kuboard.cn/install/v3/install.html

（2）下载 yaml 文件


1)第一种方式
wget https://addons.kuboard.cn/kuboard/kuboard-v3.yaml
 
2）第二种方式
#华为云的镜像仓库替代 docker hub 分发 Kuboard 所需要的镜像
wget https://addons.kuboard.cn/kuboard/kuboard-v3-swr.yaml

这里采用第1种方式

（3）node2节点拉取kuboard镜像

[root@node2 ~]# docker pull eipwork/kuboard:v3

查看镜像

[root@node2 ~]# docker images

（4）node2节点拉取etcd-host镜像

[root@node2 ~]# docker pull eipwork/etcd-host:3.4.16-2

查看镜像

[root@node2 ~]# docker images

（5）导出Docker镜像


[root@node2 ~]# docker save -o etcd-host.tar eipwork/etcd-host:3.4.16-2
 
[root@node2 ~]# docker save -o kuboard.tar eipwork/kuboard:v3

（6）复制Docker镜像到node1节点


[root@node2 ~]# scp etcd-host.tar root@node1:~
 
[root@node2 ~]# scp kuboard.tar root@node1:~

（7）node1节点导入Docker镜像


[root@node1 ~]# docker load -i etcd-host.tar
 
[root@node1 ~]# docker load -i kuboard.tar

查看镜像

[root@node1 ~]# docker images

（8）修改镜像拉取策略

[root@master ~]# vim kuboard-v3.yaml

修改前：

修改后：

（9）master节点生成资源

[root@master ~]# kubectl apply -f kuboard-v3.yaml

（4）观察pod与删除pod

注意kuboard-v3如果Ready一直为0/1，需要修改配置文件(具体可以参考后面的第二种方式)。

[root@master ~]# kubectl get pods -n kuboard -o wide -w

删除

[root@master ~]kubectl delete -f kuboard-v3.yaml

3.K8S 1.29版本部署Kuboard (第二种方式)

（1）查阅


1）官网
https://kuboard.cn/
 
2）安装说明
https://kuboard.cn/install/v3/install.html

（2）下载 yaml 文件


1)第一种方式
wget https://addons.kuboard.cn/kuboard/kuboard-v3.yaml
 
2）第二种方式
#华为云的镜像仓库替代 docker hub 分发 Kuboard 所需要的镜像
wget https://addons.kuboard.cn/kuboard/kuboard-v3-swr.yaml

这里采用第二种方式

（3）node2节点拉取镜像

[root@node2 ~]# docker pull eipwork/kuboard:v3

[root@node2 ~]# docker pull swr.cn-east-2.myhuaweicloud.com/kuboard/etcd-host:3.4.16-2

查看镜像

[root@node2 ~]# docker images

[root@node2 ~]# docker images | grep myhuaweicloud

（5）导出Docker镜像


[root@node2 ~]# docker save -o etcd-host.tar swr.cn-east-2.myhuaweicloud.com/kuboard/etcd-host:3.4.16-2
 
[root@node2 ~]# docker save -o kuboard.tar swr.cn-east-2.myhuaweicloud.com/kuboard/kuboard:v3

（6）复制Docker镜像到node1节点


[root@node2 ~]# scp etcd-host.tar root@node1:~
 
[root@node2 ~]# scp kuboard.tar root@node1:~

（7）node1节点导入Docker镜像


[root@node1 ~]# docker load -i etcd-host.tar
 
[root@node1 ~]# docker load -i kuboard.tar

查看镜像

[root@node1 ~]# docker images

（8）修改镜像拉取策略

修改前：

修改后：

（9）master节点生成资源

[root@master ~]# kubectl apply -f kuboard-v3-swr.yaml

（4）观察pod

[root@master ~]#  kubectl get pods -n kuboard -o wide -w

（5）查看日志


[root@master ~]# kubectl logs -f kuboard-v3-6fdbd869b7-5g8lv -n kuboard

重点是最后的报错

（6）编辑配置文件

[root@master ~]# kubectl edit cm kuboard-v3-config -n kuboard

查看：

（7）搜索此配置项,将此配置项替换

替换前：

KUBOARD_SERVER_NODE_PORT: '30080'

替换后：（k8s节点的任意IP）

KUBOARD_ENDPOINT: 'http://192.168.204.10:30080'

（8）删除之前的 pod 让它自己拉起来

[root@master ~]# kubectl delete pod kuboard-v3-6fdbd869b7-5g8lv -n kuboard

（9）查看pod

[root@master ~]#  kubectl get pods -n kuboard

详细信息

[root@master ~]# kubectl get pods -n kuboard -o wide

(10) 查看日志


[root@master ~]# kubectl logs -f kuboard-v3-6fdbd869b7-7xh4t -n kuboard

4.K8S 1.29版本使用Kuboard

（1）访问系统

http://192.168.204.10:30080

(2) 输入初始用户名和密码，并登录


用户名： admin
 
密码： Kuboard123

(3) 查看集群列表

目前为空

http://192.168.204.10:30080/kuboard/cluster

（4）添加k8s集群

添加

弹框

master节点查看

[root@master ~]# cat /etc/kubernetes/admin.conf

粘贴内容并确认

完成添加

http://192.168.204.10:30080/kubernetes/K8S-1.29/cluster/import

（5）再次查看集群列表

（6）访问集群

选择其中一个方式

（7）查看概要信息

http://192.168.204.10:30080/kubernetes/K8S-1.29/cluster/overview

（8）查看节点信息

http://192.168.204.10:30080/kubernetes/K8S-1.29/cluster/node

（9）查看名称空间

http://192.168.204.10:30080/kubernetes/K8S-1.29/cluster/namespace

二、问题

1.docker如何在node节点间移动镜像

（1）命令


1）在第一台服务器上导出Docker镜像
docker save -o <镜像文件名>.tar <镜像名>
 
2）将导出的Docker镜像文件从第一台服务器复制到第二台服务器
scp <镜像文件名>.tar <用户名>@<第二台服务器IP地址>:<目标路径>
连接服务器也可以使用ssh连接
 
scp <镜像文件名>.tar ssh -p 端口号 用户名@服务器地址:<目标路径>
 
3）在第二台服务器上导入Docker镜像
docker load -i <镜像文件名>.tar
 
4）其他
提示没有目录的话就创建目录，创建目录命令：
mkdir [目录名称]
