安装kuboard

AI 摘要

在 Kubernetes 集群中安装 kuboard V4，通过创建数据库、命名空间、secret、deployment、svc 和 ingress 资源清单完成部署；访问时遇到 ingress 重定向问题，最终定位为虚拟机暂停后时间未同步导致 cookie 异常。

一、引子

有时候需要一个可视化面板来管理 K8s，各种场景下都强制使用命令行是不合理的。

kuboard 有 V3、V4 版本，自己实验环境的集群版本较新，只能安装 V4 版本.

官方安装文档

二、安装

2.1 创建数据库

CREATE DATABASE kuboard DEFAULT CHARACTER SET = 'utf8mb4' DEFAULT COLLATE = 'utf8mb4_unicode_ci';
create user 'kuboard'@'192.168.10.%' identified by 'Kuboard123';
grant all privileges on kuboard.* to 'kuboard'@'192.168.10.%';
FLUSH PRIVILEGES;

2.2 创建资源清单

创建命名空间、

1	kubectl create namespace kuboard

创建 secret 来存数据库密码

1 2	kubectl create secret generic kuboard-db -n kuboard \ --from-literal=DB_PASSWORD='Kuboard123'
