Dex是一个开源的第三方身份认证系统，简化了与已有身份提供者或其他认证服务进行认证的开发流程，Dex将检查身份的过程对项目开发者隐藏，使得开发者只需要关注、控制认证业务进行的客体，无需亲自管理身份认证的各项细节
环境 OS：Debian-12.10.0-amd64 Kubernetes：v1.28.0 kubectl：v1.28.2 Helm：v3.17.3 master机已安装Git，已部署LDAP服务器
开发者没有备案的域名，无法进行DNS A解析，只能使用自签名证书
获取dex-k8s-authenticator Dex本身是可以直接使用的，但是如果想要将Dex部署至K8s集群中并提供友好的可视页面，则需要部署dex-k8s-authenticator（之后简称DKA）
执行：git clone https://github.com/mintel/dex-k8s-authenticator.git克隆该Git仓库，仓库的charts/路径中已经存在Dex和DKA的Chart文件，因此无需再单独克隆获取Dex文件
ficn@master:~$ git clone https://github.com/mintel/dex-k8s-authenticator.git ficn@master:~$ cd dex-k8s-authenticator/ ficn@master:~/dex-k8s-authenticator$ ls charts/ dex dex-k8s-authenticator README.md 运行Dex和DKA 执行：
helm inspect values charts/dex > dex-values.yaml helm inspect values charts/dex-k8s-authenticator > dka-values.yaml 这两个指令目的是根据Dex和DKA的原始Chart生成各自的新values文件，用于之后覆盖原配置
接下来就对这两个values文件进行修改
