关于kubernetes:Kuberneters-搭建openLDAP

要装置一系列的工具，如：jenkins spinnaker gitlab。账号零碎是一件烦人的事件。前两年本人也试过 openladap 这样的对立账号治理认证。当初就想再用一下. 把几个软件的账户零碎整合一下（次要是想上 spinnaker 了）。搭建形式根本参照：https://mutoulazy.github.io/2021/04/01/kubernetes/openLDAP/#%E5%9C%A8k8s%E4%B8%AD%E9%83%A8%E7%BD%B2。不过这个哥们写的配置文件也比拟乱，起码的 pv,pvc 应该先创立吧？yaml 程序整的杂七乱八的都是创立了服务后导出的 …..，另外还有这里两个的能够参考：Kubernetes – – k8s – v1.12.3 OpenLDAP 对立认证 kubernetes 实战 (十一)：k8s 应用 openLDAP 对立认证
反正就联合这几个搞一下吧！

默认存储 cbs，间接应用了腾讯云的 cbs 块存储（最小 10G 的步长也是 10G）

深深的感触到了远古页面的感觉：

先整到这里，而后测试一下 spinnaker 集成。快一年没有搞了，整通了一起测试写一下 spinnaker jenkins 等利用的集成！

关于kubernetes:Kuberneters-搭建openLDAP

背景：

kubernetes 搭建 openLDAP

1. 创立 pvc

2. 创立 ldap deployment svc 服务

3. 创立 phpldap deployments svc 服务

4. 创立 ingress 代理

5. 验证
