Cloudflare Controller for Kubernetes

I developed a Cloudflare controller, 它维护了Cloudflare和Kubernetes集群之间基于入口资源注释的Argo隧道配置. 开发背后的动机是确保将应用程序配置到Kubernetes的完全自动化过程. Without the controller, every time a new application was provisioned, 需要有人在Cloudflare中手动启用一个新的应用程序. This was very useful for CI/CD pipeline previews, 哪一种可以每天生成几次新应用程序，并允许开发人员立即看到更改. 控制器是用Go语言编写的，并作为舵机图部署.

Streamlined Application Deployment to Kubernetes

我设计并实现了Kubernetes的流线型应用程序部署, 使用Terraform操作符和Terraform代码作为部署的一部分自动部署任何外部云资源依赖. Helm chart deployed workspace CRDs into Kubernetes, 这些数据被运营商收集起来，并在云API上执行. Once completed, 输出被带回到Kubernetes，供应用程序本身用于配置.

一个使用Kubernetes容器作为slave的Jenkins自动化作业创建框架

I designed, coded, 并使用Groovy维护了一个Jenkins作业创建框架, DSL, and Jenkins pipelines. 该框架允许轻松配置和部署新作业，以及快速批量更改现有作业. The pipeline incorporated the Hashicorp vault as central, secure storage for Jenkins configuration and job builds. Kubernetes containers were used as slaves for builds. 构建过程的每一步都被定义为一个Docker映像, 允许我们使用不同的工具轻松地在相同的源代码上构建，或者确保在产品的生命周期中版本保持不变.
